When Prophesy Fails (Festinger, 1954):
A (Late Night) Field Observation of CD Festinger and associates read news article about doomsday cult: Marian Keech (L.R. Hubbard associate) receives "automatic writing" message from Planet Clarion--world to end in great flood on 12/21/ Keech and followers prepare for rescuing flying saucer by leaving spouses, jobs, college, and giving away money and possessions. Festinger et al. infiltrate cult to observe.

When Prophesy Fails (Festinger, 1954): Sequence of Events
Group develops belief system from automatic writing [facilitated communication?] Messages state world ends in great flood on 12/20/1954 at 7:00 AM, except for Keech and followers, to be rescued at midnight. Dec Rescue Day: At midnight Visitors to rescue cult; all metallic items removed (watches, bras, belts, zippers) 12:05 -- No Visitors!!! Clock may be running fast; wait 5 more min. 12:10 -- No Visitors!!! Group sits in stunned silence. Cataclysm only 7 hrs away!! 4:00 -- Group sits in stunned silence. Keech begins to cry. 4:45 -- Another message via auto-writing: Destruction called off b/c of faith of little group of believers!!! Afternoon -- Group no longer publicity shy; begins urgent campaign to spread its message.

Brehm (1956): Spreading of Alternatives Following Choice
Ss rate two appliances of near equal appeal (e.g., toaster, can-opener) How much do you like the toaster? Not At All Greatly 1 2 3 4 5 6 7 How much do you like the can opener? Not At All Greatly 1 2 3 4 5 6 7 At a later time, Ss choose between appliances. “Uh, I dunno. I guess the can opener.”
9
Brehm (1956): Continued Ss then re-rate how much they like chosen, dislike rejected Time 2 ratings compared to Time 1 Ratings. Finding? How much do you like the toaster? Not At All Greatly 1 2 3 4 5 6 7 How much do you like the can opener? Not At All Greatly 1 2 3 4 5 6 7 Selected item liked more, rejected item liked less. Why? Cognizance of selected items deficiencies, rejected items benefits, creates dissonance. Dissonance alleviated by enhancing chosen, denigrating rejected. Social, inter-group, interpersonal implications?

College Choice, Dissonance, and Theology
Colleague explains "Spreading of Alternatives to her class. Imagine you were accepted by two colleges, of near equal appeal, perhaps for different reasons. College A has better social life, College B has better academics. You can only attend one. Creates a crisis. You pick College A. After you make choice College A seems like a much better school, and College B seems less good. This is dissonance reduction. Student approaches instructor, says had exactly this crisis. \ Prayed for insight, and after making choice it all made sense. But, you're saying it wasn't The Lord, it was (pointing at PowerPoint slide) THAT!?!

Aronson & Mills Initiation Study, 1959
1. Ss go through a difficult or easy initiation in order to qualify to join a sex-issues discussion group. 2. Group turns out to be dull and boring. Which subjects experience the most dissonance? Easy Initiation X Hard Initiation Which group is more likely to rate the dull discussion group as more interesting? Easy Initiation X Hard Initiation Why? Paid high cost for unsatisfying outcome "Under-justification".
12
Festinger & Carlsmith, 1959 "Believing Own Lies"
1. Ss perform very dull task, repeatedly. 2. Ss asked to inform next subject that the task is interesting. 3. Ss offered low pay ($1) or high pay ($20) to lie. 4. Ss later asked to rate how interesting they found the task. Which group experiences most dissonance? X $1 $20 Which group rates the task as more interesting? X $1 $20 Why? $1 = low justification dissonance
13
Dissonance and Behavioral Control: Robbie the Robot Study Lepper, 1972
1. Child rates toys, including desirable "Robbie the Robot". 2. E. leaves room, tells child "don't play w' Robbie, and if you do:" a. Low threat: I will be a little annoyed with you. b. High threat: I will be very angry, and will do something. 3. Child returns to study later, new E., can play with any toy including R. the R. 4. Which child plays w' R the R? Low threat or high threat? Why? Low threat X High threat Why? Low threat = under-justification dissonance
14
Dissonance Disrupts Behaviorism
Premise of behaviorism: Punishments are negatively reinforcing. Question: What conditions produce more liking of neutral stims? Neutral Stimuli Dull discussion group Fill bin with spools Mediocre toys Reinforcement Embarrassment Low pay Punishment threat Beh. Predicts CD Shows Dislike Liking
15
Self Perception Theory Challenges Cog. Dissonance
Cog. Dissonance Theory: Discordance btwn. actions and beliefs creates negative arousal. Hence, dissonance is motivational/affective Daryl Bem: No need to posit any underlying arousal. Could be purely self-perception. People evaluate own actions as they would others. NOTE: Harks back to "Symbolic Interactionism" No internal conflict or complex motives, just attributions based on self-observed behavior.
16
Testing Self-Perception Vs. Dissonance Bem & McConnell, 1970
Premise: We infer own attitudes from our most recent behavior Beh. due to "insufficient justification", infer corresponding attitude After new attitude adopted, old attitude will be forgotten. No "change in attitude" Instead earlier attitude "overwritten" by self-perceived new attitude. Method: Counter-Attitudinal Essay, low justification vs. high justification DV: Attitude recall Result: Which group better recalls initial attitude, low or high justification? High justification. Why? Saw selves voicing views under powerful external pressure. Views voiced under pressure probably not sincere.
17
Arousal as a Necessary Condition for Cog. Diss. and Attitude Change
Cooper, Zanna, & Taves, 1978 Premise: Damn you Bem, it is arousal!!!! If arousal, then if arousal dampened, less CD; if arousal boosted, more CD "Attitudes will change following counter-attitudinal behavior if and only if arousal accompanies behavior." Method: Ss complete counter-attitudinal essay--"Should Richard Nixon be pardoned?" Either high-choice or low choice conditions. Before essay, as part of "separate study" Ss ingest pill. Told it is placebo but in actuality it is either: tranquilizer, placebo, amphetamine Predict: Attitude change in "high choice" but not if pill is _____________? Tranquilizer
