Episode 325 – Cognitive Dissonance – Part Two (rebroadcast)
Date: October 27, 2025
Host: David McRaney
Guest: Dr. Sarah Stein Labrano, political scientist and theorist

Episode Overview

This episode continues the exploration of cognitive dissonance—a foundational concept in psychology first articulated by Leon Festinger. The discussion dives deeply into the seminal Festinger-Carlsmith experiment, the mechanisms behind cognitive dissonance, its roots in psychological history, and its pervasive role in individual, societal, and political behavior. The episode closes by examining how understanding cognitive dissonance might be used to promote positive change.

Key Topics & Insights

1. The Landmark Festinger-Carlsmith Experiment

• Background

  • Festinger coined "cognitive dissonance" after observing a doomsday cult double down on mistaken beliefs when their prophecy failed (03:30).
  • He sought to quantify these psychological phenomena in controlled settings, leading to a historical experiment with Merle Carlsmith.

• The Study Design
  (07:05–14:28)

  • 71 Stanford students performed dull, repetitive tasks designed to be excruciatingly boring (moving spools, turning pegs).
  • Afterward, students were asked (with varying incentive amounts: $1 ≈ $9 today, $20 ≈ $190 today) to tell the next "participant" the task was interesting—this was a staged lie.
  • Students then rated their true enjoyment of the task.

• The Results

  • Students paid $20 freely admitted the task was boring.
  • Students paid $1 began to believe, and insist, the task was interesting—even after delay.
  • Key Mechanism: Those with insufficient external justification unconsciously changed their attitudes to reduce inner conflict.
  • Memorable Moment:
    • “They really did feel that way. After lying about how they felt, they then changed how they felt so that it would not be a lie…from that point forward, it was fun to them.” – Dr. Stein Labrano (15:22)

• Implications

  • The experiment reveals people often revise their own attitudes to relieve inner contradiction—even without realizing it.

2. Defining Cognitive Dissonance

(30:44–33:20)

• Formal Definition:

  • Cognitive dissonance is the discomfort (often unconscious) experienced when confronted with contradictions between beliefs, or between beliefs and actions.
  • Often resolved through rationalization or self-deception.
  • “Most people experiencing dissonance don't appear to be conscious of what is happening for them. We find clever ways to get rid of the discomfort without noticing we've done that.” — David McRaney (30:44)

• Not Hypocrisy Alone:

  • Sometimes it’s just ambivalence, not always about moral failings.

3. Psychology’s Historical Shift and Dissonance Theory’s Place

(33:20–38:14)

• Cognitive dissonance theory emerged as psychology shifted from behaviorism (focus on conditioning) to cognition (focus on mental processes).
• Old models saw humans as animals responding to reward and punishment, while cognitive theories recognized the brain’s role in actively constructing meaning.

4. Other Forms of Dissonance & Empirical Expansion

(38:14–46:03)

• Effort Justification: Suffering for a group or task increases valuation of that group/task (ex: hazing, difficult goals).

• Post-Decision Dissonance: After making difficult choices, we retroactively enhance our opinion of the chosen option.

• Hypocrisy Paradigm: Pointing out personal inconsistencies (like advocating for a behavior one hasn’t followed) can prompt genuine behavior change.

• Agency Matters: Dissonance peaks when people feel they had a real choice in their action.

• Bodily Systems:

  • Physiological correlates: anterior cingulate cortex (error detection), prefrontal cortex (higher reasoning), dopamine (learning & reward), sympathetic nervous system (anxiety).
  • Unresolved dissonance activates these systems; resolving it releases "relaxing" dopamine.

5. When Do We Experience Disonance? The "Genre" of Threats

(46:03–49:55)

• Dissonance doesn't show up everywhere—mainly when self-image or sense of agency is at stake.

• For neutral facts (e.g., weather), people easily update beliefs.

• For deeply-held or identity-relevant beliefs (politics, religion, morality), dissonance is chronic and hard to overcome.

  • Notable Quote:
    “Dissonance is happening only around issues that either make us feel like we are bad people or make us feel like our actions...are causing a contradiction. That's actually a relatively small part of our lives...But politics is the big one.” – David McRaney (46:46)

6. Cognitive Dissonance and Society: Potential Harms and Good

(48:27–52:14)

• Dissonance plays a role in both personal and societal stubbornness (e.g., cults increasing commitment after failed prophecies).
• While potentially adaptive, in modern environments saturated with contradicting information and rapid change, dissonance can foster entrenchment and division.

7. How Can We Use This Knowledge?

(51:01–57:30)

• Persuasion & Policy:

  • Direct argument rarely changes minds on core beliefs; enabling people to act in new ways can prompt attitude change.
  • Change occurs when individuals:
    • Articulate and confront their own ambivalence (ex: “deep canvassing” conversations).
    • Build new social relationships or participate in alternative actions (e.g., voting, climate-positive behaviors).
    • Maintain their sense of self as a “good person” in the context of new actions.
  • Example Quote:
    “If we give people opportunities to try new ways of living or form new relationships, they are much more likely to change their mind than if we just give them a bunch of arguments.” – Dr. Sarah Stein Labrano (56:21)
  • Social context matters most—people shift positions when they see peers do so, or when their in-group actions change.

• Modern Challenges:

  • Declining social mixing and “social capital” make attitude change less likely; opportunities must be created for people to interact with those unlike themselves.

Notable Quotes & Timestamps

• On the Experiment’s Core Insight:
  • “They really did feel that way. After lying about how they felt, they then changed how they felt so that it would not be a lie.” – Dr. Stein Labrano (15:22)
• On the Unconscious Nature of Dissonance:
  • “We find clever ways to get rid of the discomfort without noticing we've done that.” – David McRaney (30:44)
• On When Dissonance Appears:
  • “Dissonance is happening only around issues that either make us feel like we are bad people or make us feel like our actions...are causing a contradiction.” – David McRaney (46:46)
• On Effective Change:
  • “If we give people opportunities to try new ways of living or form new relationships, they are much more likely to change their mind than if we just give them a bunch of arguments.” – Dr. Sarah Stein Labrano (56:21)

Overall Tone

The dialogue is inquisitive, friendly, and open about uncertainty. Both host and guest blend historical anecdote, scientific rigor, and a touch of wry humor. There is sincere unease—and hope—in recognizing our cognitive quirks, but also an optimistic search for how to harness self-storytelling for societal good.

Takeaways for Listeners

• Much of what we believe about ourselves and our choices is subject to unconscious rationalization to avoid psychic discomfort.
• Simple arguments rarely persuade on core or identity-linked beliefs; change is more likely when new social circumstances, relationships, or actions allow one to sustain a positive self-story.
• Our brains are wired to defend our sense of self—sometimes at the cost of accuracy.
• Solutions for societal divides may lie in expanding opportunities for social mixing and new cooperative experiences, not just in spreading better arguments.
