Week 3 Flashcards
What are heuristics?
Heuristics are simple rules of thumb that guide our behavior
3 characteristics of heuristics
- They are triggered by external stimuli that require you to evaluate something or make a decision
- The heuristics replaces the original question with a simpler one that is easier to answer: they simplify reality
- Heuristics are adaptive, which means that they help you to respond effectively to a situation, in a way that will lead to a correct decision in most cases
Representativeness heuristic
We base our evaluations of objects, people or events on how representative they are of a certain prototype / how much they resemble a typical example
It helps to asses probabilities
“If A resembles B, is must be related to B”
COGNITIVE
Availability heuristic
If you can easily remember a certain object, event or behaviour, you probably think that it is more common than it really is
It helps us to assess frequencies
COGNITIVE
Anchoring and adjustment heuristic
The first thing (number) you see, is called the anchor. You adjust subsequent judgements based on this anchor.
An anchor value is most influential when it is active in our working memory as we are making our assessment
Even happens when you are presented with figures utterly irrelevant to the matter in hand
COGNITIVE
Affect heuristic
We are led by our feelings rather than thorough consideration of the pros and cons of particular options
If we feel positive about X, then it must have more pros than cons
COGNITIVE
More-is-better heuristic
If there is more of something, it must be better –> if something is more expensive, it must be of better quality
COGNITIVE
Content framing
The content of the message is tailored to the target group, only certain aspects are focused on; those aspects are made more salient in the message
Gain framing
- Positive phrasing
- More effective when risk of behavior is low –> risk avoidance
- Behavior that PREVENTS diseases
- People want to keep what they already have
Loss framing
- Negative phrasing
- More effecting when risk of behavior is high –> engenders risk taking
- Behavior that DETECTS diseases
- People don’t want to LOSE what they have
Cognitive heuristics
Simple rules of thumb to assess arguments presented to us, and to estimate probabilities of pros and cons
Social heuristics
Social heuristics specifically have to do with a social aspect, the influence of other PEOPLE on our judgments
Authority heuristic
This heuristic is used when someone believes the opinion of a person or authority is correct, simply because this individual is an authority or expert
We rely on their opinions and advise on the grounds of their expertise
Likeability heuristic + 4 factors
We more easily comply with requests from people we like than from someone we do not know or do not like
4 factors:
- Similarity
- Familiarity
- Helpfulness + compliments
- Physical attractiveness
Consistency heuristic
We like to be consistent in our thoughts, words, and actions, otherwise we feel cognitive dissonance.
We then feel the need to change our attitude or behaviour in order to achieve a sense of consistency between our acts and our attitudes; we aim to bring them in line
