Social Influence – Types of Influence

Why Social Influence Matters More Than You Think

Picture this: You're scrolling through your phone, and you notice everyone in your friend group is suddenly using a new app. Without much thought, you download it too. Or you're in a team meeting at work, and despite having serious doubts about the proposed strategy, you stay silent because everyone else seems on board. These everyday moments reveal something fundamental about human psychology—we're constantly being influenced by others, often without realizing it.

For the EPPP, understanding social influence isn't just about memorizing studies. It's about grasping why clients might struggle to leave toxic relationships, why group therapy can go sideways, or why a patient might continue harmful behaviors simply because their peer group does. This material shows up consistently on the exam because it's woven throughout clinical practice.

Social influence comes in three main flavors: obedience (following orders from authority), conformity (matching our behavior to group norms), and compliance (saying yes to direct requests). Each operates differently and taps into different psychological mechanisms. Let's break them down in ways that stick.

When Authority Goes Too Far: Milgram's Shocking Discovery

In the 1970s, Stanley Milgram conducted what became the most famous (and controversial) study in social psychology. He wanted to understand a disturbing question: Would ordinary people harm others simply because an authority figure told them to?

Here's how it worked: Participants thought they were helping with a learning experiment. They played the role of "teacher" while a "learner" (secretly working with the researchers) sat in another room. The teacher's job was to deliver electric shocks whenever the learner made a mistake, increasing the shock intensity with each error. The shocks weren't real, but the teachers didn't know that.

Before running the study, Milgram asked psychiatrists to predict the results. They figured maybe 1 in 1,000 people—only those with serious psychological issues—would deliver the maximum shock level. They were spectacularly wrong. The majority of both men and women delivered what they believed were dangerous, potentially lethal shocks, even as they heard the learner screaming in pain and eventually going silent.

Think about that for a moment. These weren't cruel people. They were regular folks who showed up thinking they'd participate in a learning study. Yet they did something they found deeply disturbing because someone in a lab coat kept saying "please continue" and "the experiment requires that you go on."

What Made People Obey?

Milgram tested different variations to understand what factors increased or decreased obedience. His findings reveal important patterns:

Milgram explained his results through what he called the agentic state—when people see themselves as simply carrying out someone else's wishes rather than acting on their own volition. It's like when you're following your boss's instructions for something you disagree with, and you mentally distance yourself by thinking "I'm just doing what I was told." You shift from feeling personally responsible to feeling like an instrument of someone else's will.

Other explanations matter too. The situation was unfamiliar, so participants weren't sure what "normal" behavior looked like. The study moved quickly, giving people little time to reflect. And the shock levels increased gradually—like how a toxic workplace doesn't turn bad overnight but slowly escalates until you're tolerating conditions you never thought you would.

Modern researchers have replicated key aspects of Milgram's work with better ethical safeguards. Burger's 2009 study stopped shocks at 150 volts and required thorough informed consent, yet 70% of participants still continued delivering shocks—not statistically different from Milgram's original 82.5% at that level. The findings hold up decades later.

Going Along to Get Along: Conformity to Groups

While obedience involves following orders from authority figures, conformity is about matching your behavior to what the group is doing. We all do this constantly—choosing what to wear, how to speak in professional settings, even what opinions to voice at a dinner party.

When Reality Gets Fuzzy: Sherif's Moving Light

Solomon Asch wasn't the first to study conformity. Sherif got there earlier in 1935 using a clever visual trick called the autokinetic phenomenon. If you stare at a stationary point of light in a completely dark room, your eyes play tricks on you and the light appears to move. It doesn't, but it genuinely seems to.

Sherif asked people to estimate how far the light moved. When participants made estimates alone, their answers varied wildly—some said a few inches, others said several feet. But here's the interesting part: when participants heard other people's estimates first (these were confederates giving planned responses), they adjusted their own estimates to match the group average. Even in follow-up sessions when they were alone again, they stuck with the group norm they'd adopted.

This demonstrates informational influence—when we conform because we think others know more than we do. In ambiguous situations where we're genuinely uncertain, we look to others as sources of information. It's like when you're new to a job and you watch how colleagues dress, when they take breaks, and how they interact with the boss. You're using social information to navigate uncertainty.

When the Answer Is Obvious: Asch's Line Study

Asch took conformity research further by testing what happens when the "correct" answer is crystal clear. He showed participants a line and asked them to match it to one of three comparison lines. The task was laughably easy—imagine being asked whether a giraffe is taller than a cat. That obvious.

But Asch planted confederates in the group who unanimously gave wrong answers. The real participant went second-to-last, hearing everyone else give the same incorrect response before their turn. About 75% of participants conformed to the group's wrong answer at least once across multiple trials, and about one-third conformed consistently.

Why would people deny what their eyes clearly showed them? This is where normative influence comes in—when we conform to avoid social rejection or ridicule. It's not that participants suddenly believed the wrong answer was correct. They knew better. But the social pressure to fit in was powerful enough to make them go along publicly, even while privately disagreeing.

Think about times you've nodded along in a meeting when everyone seemed excited about an idea you thought was terrible. Or when you didn't speak up about a friend's questionable relationship choice because the whole group seemed supportive. That's normative influence in action.

Getting to Yes: Compliance Techniques

Unlike obedience (following orders) and conformity (matching group behavior), compliance involves responding to direct requests. There's no authority telling you what to do, and you might be alone rather than in a group. Someone simply asks you for something. Yet certain techniques dramatically increase the odds you'll say yes.

The Foot-in-the-Door: Start Small, Ask Big

This two-step technique starts with a small, reasonable request that most people would grant. Once you agree, the requester follows up with a much larger request—the one they wanted all along.

Here's a classic example from everyday life: A colleague asks if you can "just quickly look over" a paragraph they wrote. No problem, right? Two minutes later, you're reading their entire 20-page report because once you started, it felt wrong to stop. Or think about how free trials work. "Just enter your email for this one free article" becomes a newsletter subscription becomes a paid membership, with each step feeling like a small continuation of what you already agreed to.

The technique works because of our psychological need for consistency. Once we've said yes to the small request, saying no to the larger one feels inconsistent with the identity we just established. You're not the kind of person who helps with a paragraph but refuses to read a full report, are you? The initial agreement creates a subtle shift in how you see yourself, and subsequent requests build on that foundation.

In clinical settings, you might use this ethically by asking a reluctant client to commit to just one session (small request) before building toward regular weekly therapy (larger request). Or asking a patient struggling with exercise to walk for five minutes daily before working up to a comprehensive fitness routine.

The Door-in-the-Face: Start Outrageous, Settle for Reasonable

This technique flips the script. Start with a huge, unreasonable request that most people will reject. When they say no, follow up immediately with a smaller, more reasonable request—again, the one you wanted all along.

Imagine a coworker asks if you can cover their entire two-week vacation shift. You decline because that's absurd. Then they ask if you could just cover their Friday afternoon. Suddenly that sounds almost generous on their part, and you're more likely to agree than if they'd asked for Friday afternoon in the first place.

Two psychological principles make this work. First, there's perceptual contrast—after hearing the outrageous request, the moderate request seems much more reasonable by comparison. It's the psychological equivalent of how a $50 shirt seems cheap after you've been looking at $200 options.

Second is the norm of reciprocity—when someone "gives in" by reducing their request, we feel obligated to reciprocate by giving in to their scaled-back version. They made a concession, so fairness dictates we should too. Never mind that their concession was planned all along.

You see this technique everywhere in negotiations. The contractor quotes an astronomical price, then "works with you" to find something more affordable. The car salesman starts with the premium package before "helping you" find a good deal on the base model. The teenager asks to go to an overnight party in another city, then settles for a local movie night with friends.

When Social Influence Backfires: Psychological Reactance

Not everyone responds to social influence by complying, conforming, or obeying. Sometimes pressure to behave a certain way triggers the exact opposite reaction. This is called psychological reactance, and it happens when we feel our personal freedom is threatened.

Think about the last time someone told you that you "have to" do something or "need to" change your behavior. Notice how that language creates instant internal resistance? That's reactance. It's why some patients become less motivated to change when they feel pressured, why "reverse psychology" sometimes works with stubborn people, and why overtly controlling managers often get less cooperation than collaborative ones.

Reactance can show up as:

• Doing the opposite of what's requested
• Acting aggressively toward the person making the request
• Devaluing what you're being pressured to do
• Asserting your freedom in other, unrelated ways

Understanding reactance matters clinically because heavy-handed interventions can backfire. A patient who feels judged or controlled might become defensive and less likely to change. This is one reason motivational interviewing emphasizes autonomy and avoids the "righting reflex"—the urge to fix someone by telling them what to do.

Real-World Applications for Clinical Practice

These concepts aren't just academic curiosities. They show up constantly in therapy and clinical work:

Obedience concerns: Clients may have trauma histories involving authority figures who abused power. Understanding obedience research helps explain why someone might have followed harmful directives from parents, religious leaders, or partners. It also reminds us to be mindful of our own authority as therapists—clients may agree with our interpretations or follow treatment suggestions not because they truly buy in, but because they see us as authority figures.

Conformity in group therapy: Group dynamics can be therapeutic when positive norms develop, but conformity pressures can also stifle individual voices. If one or two dominant members express certain viewpoints, quieter members might conform rather than risk rejection. Skilled group therapists watch for this and actively create space for dissenting opinions.

Compliance techniques in everyday life: Your clients are constantly targeted with these techniques—from salespeople, from manipulative partners, from well-meaning but pushy family members. Teaching clients to recognize foot-in-the-door and door-in-the-face techniques can help them set better boundaries and make more autonomous decisions.

Reactance in therapy: When clients resist treatment recommendations, it might not be denial or lack of insight. They might be experiencing reactance because they feel controlled. Adjusting your approach to emphasize choice and collaboration often reduces resistance.

Common Misconceptions to Avoid

Misconception #1: "Only weak or unintelligent people conform or obey."

Reality: Milgram's participants were ordinary people, and intelligence doesn't protect against social influence. In fact, being aware of these dynamics doesn't necessarily make you immune. Even psychology professionals fall prey to conformity and obedience pressures.

Misconception #2: "Conformity is always bad."

Reality: Conformity serves important social functions. Following traffic laws, professional dress codes, and basic social etiquette all involve conformity. The key is distinguishing between helpful social coordination and harmful suppression of important dissent.

Misconception #3: "The Milgram study proves people are naturally cruel."

Reality: Participants in Milgram's studies showed signs of extreme stress—sweating, trembling, nervous laughter. They weren't sadists enjoying the task. The study reveals how situational factors can lead even compassionate people to act against their values.

Misconception #4: "Compliance techniques are manipulative and unethical."

Reality: Like most psychological tools, these techniques are ethically neutral. They can be used manipulatively (by scammers or abusive partners) or constructively (helping a client commit to treatment or encouraging healthy behavior changes). Intent and context matter.

Misconception #5: "Normative and informational influence are mutually exclusive."

Reality: Both types of influence can operate simultaneously. In many situations, we conform both because we think others might be right (informational) and because we don't want to be rejected (normative).

Practice Tips for Remembering

For Milgram's variations, think about the three D's: Distance, Dignity, and Direct supervision. Obedience decreased when there was less distance from the victim, less dignity/prestige of the setting, and less direct supervision from authority.

For types of conformity, remember: Informational influence occurs when we're incertain (both start with "in"). Normative influence involves following group norms to fit in socially.

For compliance techniques, use physical imagery:

• Foot-in-the-door: Imagine a door gradually opening wider (small to large)
• Door-in-the-face: Imagine a door slamming shut, then opening just a crack (large to small)

For agentic state, think "agent" like a secret agent—someone who carries out orders from higher-ups and doesn't take personal responsibility for actions.

For reactance, remember it's a "reaction" against threats to freedom—the name tells you what it means.

Create a comparison table in your notes:

Key Takeaways

• Social influence takes three main forms: obedience to authority, conformity to group norms, and compliance with direct requests. Each operates through different psychological mechanisms.

• Milgram's research showed that ordinary people will follow authority orders to harm others, especially when the authority is legitimate, physically present, and the victim is distant. This demonstrates the agentic state where people see themselves as carrying out someone else's wishes.

• Conformity operates differently depending on whether situations are ambiguous or clear. Informational influence (thinking others know more) leads to genuine belief change in uncertain situations. Normative influence (avoiding rejection) leads to public compliance without private acceptance in obvious situations.

• Compliance techniques work because they tap into psychological principles. Foot-in-the-door uses our need for consistency, while door-in-the-face uses perceptual contrast and reciprocity norms.

• Psychological reactance occurs when influence attempts threaten personal freedom, causing people to resist or do the opposite. This matters clinically because heavy-handed interventions can backfire.

• These aren't just historical studies—modern replications show similar results, and these dynamics appear constantly in clinical work, from group therapy to understanding client resistance to recognizing how clients are influenced by others in their lives.

• Understanding doesn't equal immunity. Even knowing about these influences doesn't fully protect you from them. Awareness helps, but situational forces remain powerful.

Remember, for the EPPP, you need to know the researchers' names (Milgram, Sherif, Asch), the basic methodology of key studies, and the theoretical explanations for why these phenomena occur. But more importantly, understand the underlying principles so you can apply them to novel scenarios on the exam.
