Cognitive Dissonance Flashcards
Impact Bias
Overestimating the intensity and duration of negative emotional reactions when negative events happen.
Cognitive Dissonance Theory
The discomfort felt when either
1. Two cognitions (beliefs, attitudes) conflict, or
2. Behaviour and cognition conflict
due to the desire to be consistent.
How do we reduce cognitive dissonance?
- Change our behaviour so we are consistent with our cognition, or
- Change our cognition so that the cognition is consistent with our behaviour, or
- Add new cognitions to justify our behaviour - especially if the behaviour has many negative outcomes and it is very difficult to change the behaviour.
- + self-affirmation
Self Affirmation
Reminding oneself of positive attributes to reduce cognitive dissonance
Why do we change our cognition?
Due to…
- Post Decision Dissonance
- Decision Permanence
- Effort Justification
Post Decision Dissonance
(Brehm’s 1956 fabulous prize study)
Spreading of alternatives occurs when we enhance the attractiveness of the chosen alternative and devalue the rejected alternatives to reduce dissonance.
Decision Permanence
(Knox & Inkster’s 1968 horse betting study)
We are more confident or happier when making a bigger decision due to the changing in cognition and justification made for our behaviour that had finalised the decision.
Decision Irrevocability
This increases dissonance and the motivation to reduce it, and is manipulated through lowballing, the tactic of offering a low sale price before inflating the price greatly which often works due to the reduction in dissonance in the buyer.
Polarising of Morality
(Mills’ 1958 cheating study)
On-the-fence attitudes about morality may be polarised upon making a moral or immoral decision.
Effort Justification
(Aronson & Mills’ 1959 imitation study)
The goal or experience may appear more attractive in an originally undesirable scenario due to the increased effort we put in to go through it.
Where is the inconsistency coming from?
- Similarly moderately attractive alternatives
- being able to recognise the cons of the alternative and the pros of the chosen - Differential in the effort put in
External Justification
Reason or explanation for dissonant personal behaviour that resides outside the individual, external rewards and punishers.
Internal Justification
Reduction of dissonance by changing something about oneself
Counterattudinal Advocacy
It occurs when we claim to have an opinion or attitude that differs from our true beliefs. What we believe begins to conform more to our lie when there is
- Little external justification or
- Insufficient punishment
Insufficient Justification
(Festinger & Carlsmith’s 1959 $1 or $20 study)
External justification acts as a new cognition when we experience dissonance, but if the external justification is not sufficient to justify the initial inconsistency, we will change one of the two original cognitions instead in order to reduce dissonance.
