Informational Power: Knowledge, Persuasion, Evidence, and Influence
Author: Ukrainian Psychological Hub · Published: September 24, 2026 · Editorial Policy
Informational power is the capacity to influence another person through information that the person understands and accepts as a reason for changing a belief, judgment, decision, or behavior. In Bertram Raven’s extension of the classic bases-of-social-power framework, its distinctive feature is not simply that one person knows something another person does not. The distinctive mechanism is persuasion through the content of information: the target comes to see the recommendation, explanation, evidence, or argument as relevant and compelling enough to guide action.
That makes informational power one of the most easily misunderstood forms of social power. It is often collapsed into expertise, authority, access to secrets, data ownership, education, propaganda, or “knowledge is power.” Those phenomena can create power, and they can interact with informational power, but they are not equivalent to Raven’s psychological construct. Informational power is about why a particular influence attempt works: the target accepts the reasons.
The strongest form of informational influence is therefore unusually portable. Once a person has accepted the rationale, the new judgment can persist even after the original source is absent. Raven described this as socially independent change: the influence has become anchored in the target’s own understanding rather than in continuing surveillance, reward, punishment, status, or deference to the source (Raven, 2008).
Modern persuasion research adds an important qualification. Information is not automatically persuasive because it is true, detailed, scientific, or available. Argument quality matters, but so do attention, motivation, prior attitudes, source credibility, selective exposure, information avoidance, identity, and the practical setting in which a message is encountered. Informational power is therefore best understood as a mechanism of influence through accepted reasons, not as a guarantee that better evidence will always win.
Informational Power: The Short Definition
In psychology, informational power is influence based on the persuasive content of information. Person A has informational power in a particular influence episode when A provides reasons, evidence, explanations, or other information that Person B evaluates as relevant and accepts, leading B to change a belief, decision, or behavior.
The key phrase is “accepts the information as a reason.” A person can possess knowledge without persuading anyone. A person can persuade through charm without supplying reasons. A manager can obtain compliance through formal authority without changing an employee’s understanding. Informational power is present when the information itself does the central psychological work.
A useful one-sentence test is this: if the source disappeared immediately after the explanation, would the target still have a reason, in their own mind, to maintain the change? When the answer is yes because the rationale has been understood and accepted, the influence has the socially independent quality Raven associated with informational power (Raven, 1993; Raven, 2008).
Informational power belongs inside the broader psychology of social power, but it should not be used as a synonym for social power as a whole. Social power includes multiple sources of influence, including control over rewards and punishments, legitimacy, expertise, identification, and information.
Where Informational Power Comes From: French, Raven, and the Sixth Base
The historical starting point is John R. P. French Jr. and Bertram Raven’s chapter “The Bases of Social Power,” published in the 1959 volume Studies in Social Power. The original chapter explicitly defined five common bases: reward, coercive, legitimate, referent, and expert power (French & Raven, 1959). Informational power was formalized later by Raven, commonly traced to his 1965 work, and was incorporated into the expanded six-base tradition discussed in his later reviews (Raven, 1993; Raven, 2008).
That historical detail matters because popular summaries often say that “French and Raven identified six powers in 1959.” The 1959 chapter itself lists five. Raven’s later work added information or persuasion as a distinct basis and then further differentiated several of the original categories. Treating the framework as historically fixed hides the fact that it evolved.
The framework is a historical social-psychological theory of interpersonal influence, not a clinical classification and not a personality test. It asks what relationship or resource makes influence possible in a specific episode. The same person can use different bases in different moments. A supervisor might rely on legitimate power to assign a task, expert power to recommend a technical method, reward power to offer an incentive, and informational power to explain why one procedure will produce a better result.
The broader Psychology of Power cluster distinguishes these bases from status, dominance, prestige, leadership, control, authority, and motivation. Informational power owns a narrower question: how knowledge, reasons, evidence, and explanation become a basis of influence.
The Core Mechanism: From Information to Socially Independent Change
Raven’s later account makes informational power distinctive by the form of change it can produce. The influencing agent presents information in a way that gives the target a reason to alter behavior or belief. If the target understands and accepts that reason, the resulting change does not have to remain psychologically tied to the agent. The target can continue acting on the conclusion because the rationale has become part of the target’s own cognitive basis for action (Raven, 2008).
This mechanism can be separated into several stages. They are analytically useful rather than a rigid sequence that every real interaction follows.
1. The information must be relevant to an outcome the target cares about
Information has little influence if it does not connect to a live judgment, goal, problem, uncertainty, or decision. A detailed explanation of server architecture has almost no informational power over a person deciding which medication to take unless the explanation bears on that choice. Relevance defines the domain in which the information can function as a reason.
This is one reason informational power is usually domain-specific. Someone may be highly informative about tax law and almost useless as a source of reasons about nutrition. Broad intelligence, education, confidence, or social status does not create universal informational power.
2. The target must be able and willing to process the message
Persuasion research shows that the impact of arguments depends partly on how much people attend to and think about them. A meta-analysis of 134 research series examining a central prediction of the elaboration likelihood model found that experimentally stronger versus weaker arguments generally produced a larger difference under conditions associated with greater central processing (Carpenter, 2015).
This does not mean that “strong arguments” in persuasion experiments are identical to objectively true claims. Argument strength is an experimental construct about persuasive responses to message content. The important implication is narrower: the psychological effect of reasons depends partly on processing conditions. An excellent explanation can have little influence when the audience is distracted, exhausted, unmotivated, unable to understand the material, or already committed to avoiding the issue.
3. The target must accept the rationale rather than merely obey the source
A change in behavior does not by itself prove informational power. Suppose an employee adopts a procedure because the supervisor ordered it. That may be legitimate power. Suppose the employee complies because refusal would be punished. That is closer to coercive power. Suppose the employee follows the recommendation because the supervisor is regarded as a technical authority, without understanding the rationale. That is expert power.
Informational power becomes the better description when the employee understands the reasons and accepts them: perhaps the new procedure reduces error because it removes an identified failure point, and the evidence or logic is persuasive. The behavioral outcome may look identical from the outside, but the psychological basis differs.
4. The change can outlast the source
Raven used the contrast between socially dependent and socially independent change to clarify why bases of power differ. Reward and coercive influence often depend on the source’s ability to keep mediating consequences. Expert influence can depend on continued deference to the expert. Informational influence can become independent because the target now possesses the rationale (Raven, 2008).
This does not mean informational influence is permanent. New evidence, forgotten details, changing goals, counterarguments, social pressures, or later experience can reverse a judgment. “Socially independent” means that maintenance of the change does not require continuing reference to the original influencing agent; it does not mean the belief has become irreversible.
5. The influence remains bounded by the information
Informational power does not automatically generalize from one successful explanation to every later topic. If a colleague convincingly explains why one statistical model is inappropriate, that does not establish authority over unrelated hiring decisions. The basis is tied to the content and the domain in which the information has persuasive force.
This is also why informational power can be shared. Once reasons become available to others, the original source may lose exclusivity while the information itself continues to influence. A convincing proof, diagnostic explanation, safety argument, or engineering analysis can travel through a group and still affect people who never met its original presenter.
Informational Power Is Not the Same as Possessing Information
The everyday phrase “information is power” covers several different mechanisms. Some are close to Raven’s informational power; others are not.
Exclusive information can create leverage. A negotiator who knows the other side’s reservation price, a manager who controls access to performance data, or a gatekeeper who knows an unpublished decision may gain strategic advantage because information is asymmetrically distributed. That advantage can alter bargaining positions and dependence even if no persuasive explanation occurs.
Raven’s informational power is narrower. It concerns influence through information that functions as a persuasive reason. Merely withholding information, possessing a database, controlling a password, or knowing a secret may create power through scarcity, dependence, or access control. Those are genuine power mechanisms, but calling all of them informational power erases the psychological distinction the construct was designed to make.
A practical distinction is therefore useful: possession of information concerns who has access to a resource; informational power concerns what accepted information does in an influence process. The two can coincide, but neither implies the other.
Informational Power vs Expert Power
Informational power and expert power are especially easy to confuse because both involve knowledge. Raven’s framework separates them according to what the target relies on.
With expert power, the target is influenced because the source is believed to have superior knowledge, skill, experience, or competence in the relevant domain. The target may not independently evaluate the reasoning. “She is the cardiologist, so I trust her recommendation” expresses expert-based influence.
With informational power, the target is influenced because the message itself supplies reasons the target accepts. “She explained how the treatment changes this risk, showed the relevant evidence, and the reasoning makes sense to me” expresses informational influence. Expertise may have opened the door to attention, but the accepted rationale now carries the change.
The difference can be summarized this way:
• Expert power asks: Why should I trust this person’s judgment?
• Informational power asks: Why should I accept this conclusion?
• Expert power is source-centered: perceived competence is the basis of influence.
• Informational power is content-centered: accepted reasons are the basis of influence.
• Expert and informational power can operate together in the same conversation.
Modern source-credibility research helps show why the distinction matters. A 2026 systematic review and meta-analysis of credible sources and observed behavior synthesized 40 effect sizes from 34 papers (N = 7,995) and found a small positive average effect, d = 0.14, with important contextual moderators (Hamer et al., 2026). Source credibility matters, but credibility is not a magic substitute for message content.
Earlier reviews likewise found that highly credible sources are often more persuasive than low-credibility sources while documenting many interactions involving message, receiver, channel, and context variables (Pornpitakpan, 2004). A meta-analysis by Kumkale, Albarracín, and Seignourel further showed that credibility effects varied with prior attitudes and the audience’s ability and motivation to form message-based attitudes (Kumkale et al., 2010).
In real communication, source and message are rarely cleanly separable. People use source credibility to decide whether a message deserves attention; they use message quality to update how credible the source seems; and prior beliefs can shape both judgments. The conceptual distinction remains useful precisely because these mechanisms can interact.
Informational Power vs Informational Social Influence
Another confusing pair of terms comes from two different traditions in social psychology: informational power and informational social influence.
Informational social influence is associated with Morton Deutsch and Harold Gerard’s classic distinction between normative and informational influence. Informational influence occurs when people treat information from others as evidence about reality, especially when their own judgment is uncertain. Their 1955 experiments extended the Asch conformity paradigm and showed that group judgments could affect individual judgments even when some public normative pressure was reduced (Deutsch & Gerard, 1955).
Informational power, in the Raven tradition, asks what basis allows one actor to influence another through persuasive information. Informational social influence asks how information from other people functions as evidence in social judgment. The constructs overlap in subject matter, but they are not interchangeable.
A person can experience informational social influence without a stable power relationship: several strangers independently choose the same emergency exit, and their behavior becomes evidence that the route is correct. Conversely, a manager can exercise informational power by giving a subordinate a detailed causal explanation even when there is no group consensus to follow.
Informational Power vs Authority, Status, and Other Bases of Power
Informational power should also be kept separate from several neighboring constructs that often travel with it.
Authority concerns a recognized right to direct, decide, or prescribe within a role or institution. Someone can possess authority without offering persuasive reasons, and someone can have informational power without holding any formal authority. The English Hub’s Power vs Authority article develops that distinction.
Status concerns respect, esteem, or social standing. High-status people may receive more attention, but their messages do not become informationally persuasive merely because they are admired. For the power-status distinction, see Power vs Status.
Referent influence depends on identification, attraction, or a desired relationship with the source. Reward power depends on control of desired benefits. Coercive power depends on the capacity to impose or mediate unwanted outcomes. Legitimate power depends on perceived rightfulness or obligation. Informational power depends on accepted reasons. Real influence attempts can combine several of these bases at once.
This is why the phrase “she convinced everyone because she is powerful” is too coarse for psychological analysis. Did people comply because she controlled resources, because her role was legitimate, because she was admired, because she was regarded as an expert, or because her explanation changed their understanding? Different answers imply different power mechanisms and different aftereffects.
Informational Power vs Personal Power and Positional Power
Popular leadership writing sometimes uses “personal power” as a broad container for expertise, relationships, credibility, charisma, and information, while “positional power” refers to formal role-based control. That shorthand can be useful in practice, but it should not replace the more precise constructs.
Informational power can be exercised by someone with a formal position or by someone with no position at all. A junior analyst may persuade a senior executive by showing a decisive pattern in the data. A director may do the same. What matters for the informational mechanism is the accepted rationale, not the organizational rank of the messenger.
For the broader distinction between autonomy, role authority, status, expertise, and influence, see Personal Power vs Positional Power. Informational power is one specific route through which influence can occur across either formal or informal relationships.
Does Evidence Automatically Create Informational Power?
No. Evidence can strengthen informational power, but evidence is not psychologically self-executing.
There are two questions that should be kept separate. The epistemic question asks whether the evidence actually supports a claim. The psychological question asks whether a particular audience notices, understands, trusts, integrates, and acts on that evidence. Informational power lives in the second process while ideally remaining anchored to the first.
An argument can be persuasive and false. A true claim can be presented so badly that it fails to persuade. A source can be credible but mistaken. A source can be distrusted while presenting accurate evidence. Psychological effectiveness is therefore not a validity certificate.
Research on persuasion shows that argument quality, source cues, prior attitudes, involvement, knowledge, and processing conditions can all change outcomes. Carpenter’s meta-analysis of the elaboration-likelihood prediction found that stronger arguments generally gained more advantage over weaker arguments under higher-processing conditions (Carpenter, 2015). But people do not approach information as neutral processors with unlimited attention.
Selective-exposure research illustrates one barrier. A meta-analysis by Hart and colleagues found a moderate overall preference for information that was congenial rather than uncongenial to existing attitudes, with both defense and accuracy motives shaping exposure (Hart et al., 2009). People can therefore reduce the influence of disconfirming information before they even evaluate its details.
Information avoidance provides another barrier. A major interdisciplinary review documented that people sometimes avoid information even when it is free and could improve decisions, because information can threaten beliefs, emotions, self-image, anticipated utility, or strategic interests (Golman, Hagmann, & Loewenstein, 2017).
Correction research shows the same basic lesson in a particularly demanding setting. Chan and Albarracín’s meta-analysis of science-relevant misinformation, corrected in 2025, synthesized 245 effect sizes from 75 reports with a total N of 53,320 and found that debunking attempts were not significantly effective on average in their pooled model, although effects varied by context (Chan & Albarracín, 2023; Author Correction, 2025).
These findings should not be turned into the slogan that facts do not matter. They show that the route from evidence to belief change has psychological conditions. Informational power is strongest when relevant evidence is intelligible, attention is available, the reasoning can be evaluated, the audience has some willingness to engage, and the communication context does not make acceptance prohibitively costly.
Persuasion, Reasoning, and the Limits of the “Rational Audience”
Raven’s informational power highlights cognition and acceptance. Contemporary persuasion science makes that picture more realistic by showing that people use multiple routes to judgment.
Sometimes people carefully scrutinize arguments. Sometimes they use shortcuts such as source expertise, consensus, familiarity, fluency, or social identity. Often both processes contribute. A physician’s explanation may be persuasive partly because the causal reasoning is understandable and partly because the physician is credible. A technical report may carry weight because its analysis is strong and because the institution is trusted. A colleague’s argument may be accepted because it fits prior knowledge and because the colleague has a record of being accurate.
For informational power, the analytically important question is not whether all peripheral cues disappear. It is whether the content of the information becomes a reason that can support the target’s judgment. The cleaner the target’s later reasoning is from “I believe this because X makes sense” rather than “I believe this because that powerful person said so,” the closer the case is to the informational ideal.
This also explains why transparent reasoning can produce a different kind of influence from opaque instruction. An opaque instruction can achieve immediate compliance. A transparent explanation can give the target a reusable model for future decisions. The second form may require more time, comprehension, and willingness to engage, but it can reduce dependence on the original source.
How Informational Power Works in Organizations
Organizations are saturated with information, yet that does not mean they are saturated with informational power. Dashboards, reports, memos, policies, analytics, slide decks, and expert briefings can all fail to influence if they are irrelevant, unintelligible, distrusted, strategically ignored, or disconnected from decisions.
Informational power becomes visible when information changes the reasons people use to choose. A safety engineer shows that a proposed shortcut increases a specific failure mode. A financial analyst demonstrates that a project’s apparent growth disappears after correcting for a reporting artifact. A nurse explains why a workflow creates a medication-error risk. A junior developer traces an outage to a reproducible dependency conflict. None of these actors needs formal authority to create influence if the reasoning is accepted.
This route to influence helps explain how people without high rank can still become consequential in groups. Expertise, network position, credibility, and access can help them get heard; informational power occurs when their explanation then changes the decision. The broader pathways by which people acquire influence are covered in How Do People Gain Power?.
The organizational value of informational power is especially clear when disagreement is permitted. If a recommendation must survive questions, counterevidence, and alternative explanations, the group can separate informational influence from mere deference more effectively. That does not eliminate hierarchy, but it creates conditions in which reasons can do more of the work.
The risk appears when organizations confuse data production with persuasion. More metrics do not necessarily create better decisions. An overloaded report can bury the decisive evidence. A dashboard can imply precision it does not possess. A technically correct analysis can fail when decision makers cannot understand its assumptions. Informational power depends on the relation between information and a target’s actual reasoning, not on the sheer volume of information.
Informational Power in Leadership
Leaders often combine several power bases. Role authority can secure attention. Reward and coercive capacity can shape compliance. Expertise can create trust. Referent influence can make followers identify with the leader. Informational power enters when the leader gives reasons that followers can understand and adopt.
This distinction matters for followership. A leader who explains why priorities changed, what evidence supports the decision, which uncertainties remain, and what would trigger revision gives followers a cognitive basis for action. A leader who says only “trust me” relies more heavily on source-based credibility or authority.
Informational power does not make leadership automatically participatory or ethical. Persuasive information can be selective, misleading, framed strategically, or used to conceal alternatives. Nor does transparency guarantee agreement. Its psychological advantage is narrower: when followers genuinely accept the reasoning, coordinated behavior can persist with less need for monitoring or repeated command.
For the broader relationship among leadership, authority, influence, status, and followership, see Power and Leadership.
Workplace hierarchies also affect who gets to speak, whose evidence is treated as credible, and what disagreement costs. Those structural issues belong to Power Dynamics at Work; they can determine whether potentially informative voices ever get the opportunity to exercise informational power.
Informational Power in Expertise and Professional Advice
Professional advice provides one of the clearest settings in which expert and informational power can be separated analytically. A client, patient, student, employee, or citizen may initially attend to a recommendation because the source has credentials. That is source-based influence. The interaction can then shift toward informational power if the source explains mechanisms, alternatives, tradeoffs, evidence, and uncertainty in a way the recipient can evaluate.
This shift is psychologically important because it changes the recipient’s role. The recipient is no longer asked only to defer; they are given a reason structure. In settings where informed choice matters, explanations can support understanding and reduce unnecessary dependence on status alone.
But technical complexity creates limits. Some judgments cannot be independently reconstructed by a nonexpert in the available time. People routinely have to rely partly on expertise, institutions, standards, and trust. Informational power should therefore not be romanticized as a world in which everyone personally verifies every claim. Real decisions often combine expert power and informational power.
Source credibility itself is also conditional. The 2026 meta-analysis of credible sources found a small average effect on observed behavior and stronger effects in some conditions, including certain in-person and professionally qualified-source contexts (Hamer et al., 2026). The finding reinforces a useful separation: credible expertise can facilitate influence, but it does not eliminate the need to examine the message and context.
Informational Power in Education
Teaching can involve informational power when explanations change how learners understand a problem. A student who adopts a method only because “the teacher requires it” is responding primarily to legitimate authority. A student who adopts it because the teacher demonstrates why it works has a different psychological basis for the same behavior.
The difference matters for transfer. When the learner understands the reason, the knowledge can be used in new settings without the teacher present. That is close to Raven’s socially independent form of change. The student can now reproduce the rationale, test it, and potentially revise it when new information appears.
Education also illustrates a limit: comprehension cannot be assumed. Explanations have informational power only to the extent that the learner can connect them to prior knowledge, follow the reasoning, and discriminate strong evidence from confident presentation. Pedagogical clarity is therefore not merely a stylistic virtue; it can change whether information becomes a usable reason.
Informational Power in Close Relationships
Close relationships contain continual attempts at influence: explanations, requests, evidence, emotional appeals, reminders, bargaining, promises, and boundary setting. Informational power is present when one partner changes a view or action because the other provides reasons that are accepted.
For example, one partner may explain how a recurring schedule affects sleep, caregiving, finances, or emotional availability and propose a different arrangement. If the other partner understands and accepts the rationale, the change can persist without repeated pressure. That differs from compliance produced by threats, punishment, withdrawal, dependency, or fear.
Persuasion should not be equated with consent, however. A person can be persuaded about one proposition without consenting to every action connected to it. Information can also be selectively presented, distorted, or combined with coercive pressure. The presence of reasons does not erase other power dynamics.
This is why broader relational analysis belongs under Power Dynamics. Informational power describes one basis of influence; it does not by itself tell us whether the relationship is symmetrical, safe, consensual, or healthy.
Information, Framing, and Manipulation
Informational power can be used responsibly or manipulatively. Raven’s construct classifies a basis of influence; it does not certify the truthfulness or ethics of the message.
A misleading argument can still alter cognition. Selective disclosure can make a conclusion appear inevitable. A chart can use accurate numbers with a distorted scale. A communicator can present only favorable studies, suppress uncertainty, or frame alternatives asymmetrically. If the target accepts the resulting rationale, the influence may look informational at the mechanism level even though the communication is epistemically poor or ethically problematic.
For practical analysis, it is useful to separate three dimensions:
• Informational mechanism: Did reasons or evidence contribute to the target’s change?
• Epistemic quality: Were the claims accurate, the evidence relevant, and the uncertainty represented fairly?
• Ethical process: Could the target question, refuse, seek alternatives, and access material information?
Keeping these dimensions separate prevents two mistakes. The first is treating all persuasion as manipulation. The second is treating all reason-giving as benevolent simply because it uses evidence-like language.
Informational Power and Foucault’s Power/Knowledge Are Different Concepts
The phrase “information is power” can also draw readers toward Michel Foucault’s work on power and knowledge. The overlap is linguistic rather than conceptual identity.
Raven’s informational power is a social-psychological category of interpersonal influence: information functions as the persuasive basis for a target’s change. Foucault’s power/knowledge concerns a much broader philosophical and historical analysis of how practices of knowledge, classification, institutions, discourse, surveillance, and normalization are entangled with relations of power.
Using Foucault to define Raven’s informational power would therefore blur two different theories. Readers looking for discipline, surveillance, normalization, subject formation, and power/knowledge should see Foucault on Power. The present article keeps the canonical intent on the psychological influence mechanism.
Informational Power in Digital Environments
Digital environments dramatically increase the volume, speed, persistence, and targeting of information, but they do not abolish the basic psychological distinction. A search result, dashboard, ranking, recommendation, AI-generated explanation, video, or social post has informational influence only when its content contributes to a person’s accepted reasons.
At the same time, digital systems can shape which information is visible before persuasion begins. Ranking, recommendation, moderation, interface design, personalization, access control, and repeated exposure can structure the informational field. Those mechanisms concern broader forms of platform and algorithmic power and should not be collapsed into Raven’s informational power.
For this article, the useful boundary is simple: informational power analyzes persuasion through accepted information; digital distribution systems analyze how access, salience, exposure, and choice environments are configured. A digital system can create the conditions under which informational power is easier or harder to exercise without itself being reducible to the interpersonal construct.
Can Informational Power Be Measured?
The French–Raven tradition has generated measurement work, but informational power is not a single universally standardized trait with one definitive score.
Raven, Schwarzwald, and Koslowsky developed an instrument intended to measure an expanded power/interaction model with 11 differentiated bases, including information. In one study, 317 American student respondents judged hypothetical supervisor-subordinate influence situations; in a second study, 101 Israeli health workers were assessed. The authors reported adequate internal consistency and a factor structure that supported several differentiated bases, although the empirical factors did not map one-to-one onto every theoretical category (Raven, Schwarzwald, & Koslowsky, 1998).
That study is historically important because it moved beyond naming the categories and attempted to operationalize them. It should not be treated as proof that the taxonomy has a single final factor structure across all cultures, settings, and forms of influence. The samples were limited, the scenarios and occupational contexts were specific, and the framework has continued to be interpreted and refined.
In contemporary research, many studies examine related mechanisms—source credibility, argument strength, expertise, trust, persuasion, social influence, information avoidance—without labeling the phenomenon “informational power.” The empirical evidence base is therefore distributed across neighboring literatures rather than concentrated in one modern informational-power scale.
What the Evidence Supports—and What It Does Not
The evidence supports several defensible conclusions.
First, informational power is a legitimate historical construct within the expanded French–Raven tradition, and Raven explicitly distinguished it from expert, legitimate, reward, coercive, and referent power (Raven, 1993; Raven, 2008).
Second, the theory’s idea that reasons can become socially independent is conceptually coherent and maps onto a familiar psychological phenomenon: people can internalize explanations and continue to act on them after the communicator is gone.
Third, modern persuasion research supports the broader proposition that message content, argument strength, source credibility, prior attitudes, motivation, and information-selection processes all affect influence. These literatures make Raven’s construct more psychologically realistic, while also showing that no simple “give people the facts” model is adequate (Carpenter, 2015; Hart et al., 2009; Kumkale et al., 2010).
The evidence does not establish that informational power is always stronger than other bases, always more ethical, or universally more durable. It does not show that accurate evidence inevitably persuades. It does not prove that people who possess more information have more interpersonal power in every context. And it does not justify treating every form of communication, education, expertise, or data control as the same construct.
The most scientifically useful position is precise: informational power is a theory-guided category for influence through accepted information, supported by historical measurement work and connected to a large contemporary literature on persuasion and information processing.
When Informational Power Is Likely to Be Stronger
Informational power is likely to be stronger when several conditions align.
• The information is directly relevant to a live decision or goal.
• The reasoning is understandable at the audience’s level of knowledge.
• The evidence is concrete enough to evaluate rather than merely asserted.
• The audience has sufficient attention and motivation to process the message.
• The communicator represents uncertainty and limitations clearly enough to sustain trust.
• The target is permitted to ask questions, seek counterevidence, and compare alternatives.
• The explanation connects new information to the target’s existing knowledge without requiring blind deference.
• The social costs of changing one’s mind are not so high that identity or group loyalty overwhelms evidential considerations.
These conditions are best understood as plausible mechanisms synthesized from persuasion research, not as a validated universal checklist. Different domains place different demands on expertise, evidence, trust, and comprehension.
When Informational Power Breaks Down
Informational power can fail even when the communicator has excellent evidence.
One failure mode is irrelevance: the message answers a question the target is not trying to solve. Another is incomprehensibility: the argument may be technically sound but inaccessible. A third is distrust: the audience may suspect selective reporting or hidden incentives. A fourth is identity threat: accepting the claim may carry social or self-concept costs. A fifth is overload: too much detail can obscure the decision-relevant structure.
Selective exposure can prevent counterattitudinal information from being encountered at all, while information avoidance can make people turn away from material they expect to find unpleasant or destabilizing (Hart et al., 2009; Golman et al., 2017).
Misinformation correction provides an especially difficult example because prior false claims can be familiar, emotionally charged, politically polarized, or integrated into causal explanations. The corrected Chan and Albarracín meta-analysis found no statistically significant average debunking effect in the pooled science-relevant misinformation model, with substantial contextual variation (Chan & Albarracín, 2023; Chan & Albarracín, 2025 correction).
The implication is not to abandon evidence. It is to treat informational influence as a psychological process that includes exposure, attention, comprehension, evaluation, memory, motivation, and social context.
How to Use Informational Power Responsibly
Responsible informational influence aims to make the target more capable of evaluating the issue, not merely more compliant with the communicator.
A strong practice is to expose the reasoning chain. State the claim, identify the evidence, explain how the evidence bears on the claim, disclose material uncertainty, and distinguish observation from inference. When alternatives exist, compare them rather than presenting a preferred option as the only imaginable choice.
It also helps to separate expertise from explanation. Credentials can justify initial attention, but they should not be used to shield an argument from scrutiny when scrutiny is possible. A communicator can say, in effect, “Here is why I think this,” not only “I am the person you should trust.”
Another principle is corrigibility. Good informational influence leaves room for revision when new evidence appears. If a message is constructed so that every counterexample becomes proof of the message, it has stopped functioning like an evidence-responsive explanation.
Finally, preserve agency where the context permits it. Giving reasons is most compatible with autonomous judgment when people can ask questions, refuse, seek a second source, and understand the consequences of alternatives. In high-stakes institutional settings, these protections can matter as much as rhetorical clarity.
Common Misconceptions About Informational Power
Misconception 1: Informational power means knowing more than other people. Knowledge can support influence, but informational power requires an influence process in which information becomes an accepted reason.
Misconception 2: Informational power and expert power are the same. Expert power relies on perceived expertise of the source; informational power relies on persuasive content. They frequently operate together.
Misconception 3: Informational power is automatically ethical. Accurate explanation can support autonomy, but information can also be selective, deceptive, manipulative, or combined with coercion.
Misconception 4: Evidence always wins. Evidence quality matters, yet exposure, comprehension, motivation, prior attitudes, source judgments, and identity can all alter whether evidence changes beliefs or behavior.
Misconception 5: Informational power is the same as informational social influence. They come from different theoretical traditions and answer different questions.
Misconception 6: French and Raven published six bases in 1959. Their 1959 chapter explicitly presented five; Raven later formalized informational power as an additional base.
Misconception 7: Once information is shared, the source has no power left. Sharing can reduce power based on exclusive access, but accepted information can continue to influence through socially independent change. Other bases of power may also remain.
Misconception 8: Informational power is a diagnosis or personality trait. It is neither. It is a social-psychological concept for a basis of influence in relationships and interactions.
Frequently Asked Questions
What is informational power in psychology?
Informational power is a basis of social influence in which a person changes a belief, judgment, decision, or behavior because they understand and accept information supplied as a reason. In Raven’s framework, the resulting change can become socially independent of the original source.
Who introduced informational power?
French and Raven’s 1959 chapter presented five bases of social power. Bertram Raven later added informational power, commonly traced to his 1965 formulation, and discussed it extensively in later revisions of the framework (Raven, 1993; Raven, 2008).
What is an example of informational power?
A project analyst shows that a proposed launch date creates a measurable capacity bottleneck, explains the assumptions, and demonstrates how a two-week change removes the bottleneck. The team changes the schedule because it accepts the reasoning. The analyst may have no authority to order the change; the information itself becomes the basis of influence.
How is informational power different from expert power?
Expert power depends on the target’s belief that the source has superior knowledge or competence. Informational power depends on the target accepting the source’s reasons or evidence. “I follow the recommendation because she is an expert” and “I follow it because her explanation convinced me” describe different psychological bases, although both can operate simultaneously.
Is informational power the same as having access to secret information?
No. Exclusive information can create strategic leverage through scarcity or dependence, but Raven’s informational power specifically concerns persuasion through accepted information. A secret can create power even if it is never used to persuade anyone.
Is informational power the same as informational social influence?
No. Informational social influence concerns using other people’s judgments or behavior as evidence about reality, a tradition associated with Deutsch and Gerard. Informational power is a Raven-style basis of interpersonal influence through persuasive information.
Is informational power a type of authority?
No. Authority concerns a recognized right to direct or decide. Informational power can be exercised by someone with no formal authority, and a person with authority can issue commands without using informational power.
Does informational power require true information?
The psychological mechanism requires information the target accepts as a reason; it does not guarantee that the information is true. For responsible use, epistemic quality must be evaluated separately: evidence should be accurate, relevant, appropriately qualified, and open to correction.
Does better evidence always produce more influence?
No. Better-supported arguments can be more persuasive under some processing conditions, but persuasion also depends on attention, prior attitudes, credibility, motivation, selective exposure, information avoidance, and context (Carpenter, 2015; Hart et al., 2009).
Why can informational power last after the source leaves?
Because the target can retain the reason. Once the explanation has been understood and accepted, continued action need not depend on remembering, monitoring, or deferring to the original communicator. Raven called this socially independent change (Raven, 2008).
Can informational power exist without hierarchy?
Yes. Peers, junior employees, friends, students, clients, and outsiders can exercise informational power if their information changes another person’s reasoning. Formal rank can affect who gets heard, but rank is not part of the definition.
Can informational power be manipulative?
Yes. Selective evidence, misleading framing, hidden uncertainty, and deceptive claims can all use informational routes to influence. Whether the mechanism is informational and whether the communication is accurate or ethical are separate questions.
