Primary questions
When do we make attributions? Do people’s attributions show any
systematic biases?
When do we make attributions?
Weiner (1985) reviewed evidence for “spontaneous causal thinking”.
Two key factors which elicit attributions
1.) Unexpected events2.) Non-attainment of a goal
Kanazawa (1992) found expectancy only an effect on causal thinking
Loss of control ( Liu & Steele, 1986) Emotions such as sadness and anger
(Keltner, Ellsworth, & Edwards, 1993)
Attributional biases
- A number of studies have suggested that in comparison to scientists or statisticians, laypeople are inaccurate in their attributions
- A bias occurs if the perceiver systematically distorts some otherwise correct procedure
2 classes of explanation for attribution biases
1.) Motivational (need) 2.) Cognitive (informational)
Why are biases in attribution interesting?
1.) They tell us about how people really do make attributions, rather than how they should
2.) Understanding bias can help us to promote social justice
Fundamental attribution error/ Correspondence bias A tendency to underestimate the impact of
situational factors and to overestimate the role of personal dispositional factors in controlling behaviour
Ross, Amabile, & Steinmetz (1977) – randomly assigned participants in quiz game to roles of contestant and ‘quiz master’ Quiz master was asked to set difficult questions
Both contestant & quiz master rated the questioner as much more knowledgeable, overlooking advantages conferred by being questioner
Issues surrounding the fundamental attribution error
• Not universal to all cultures (Miller,1984). • No criteria for accuracy, thus referred to as correspondence bias.
Explanations of correspondence bias
Motivational – Dispositional attribution gives us a sense of control
- just world hypothesis Cognitive – emphasise knowledge base of
attributions and social information processing.
- Salience explanation (Rholes & Prior, 1982)- Differential rates of forgetting (Peterson,
1980) (counter evidence – Burger, 1991)
Actor-observer differences (divergence)
Actors (self) attribute their actions to situational factors whereas the observer (other) tends to attribute the same actions to stable personal dispositions.
e.g. Shyness in tutorial group
Explanations of Actor-observer differences
Cognitive explanations
1.) A greater amount of information available to the actors or self-raters
2.) Focus of attention (perceptual explanation)
Perceptual explanation of the actor- observer effect
Storms (1973) found actors became less situational, and observers more situational when shown new orientation of the situation.
Actor-Observer differences Motivational component
Buehler, Griffin & Ross (1995)- extended the actor-observer differences to other kinds of judgement and found motivational component
Found individuals tend to underestimate how long it would take them to complete a task, whereas they would predict others would take longer to do the task
Self-serving bias Tendency to attribute one’s success to internal
causes, but attribute failures to external causes E.g. Kingdon (1967) interviewed successful &
unsuccessful American politicians about major factors in successes & failures. Tended to attribute wins to internal factors (hard work, reputation) but failures to external (lack of money, national trends)
Actually involves 2 two biases – 1.) self-enhancing bias (taking credit for success)
2.) Self-protecting bias (denying responsibility for failure)
Self-handicapping bias – more subtle form of self-serving bias
Explanations of self-serving bias
Cognitive explanation - Miller & Ross (1975) If people intend to succeed, then behaviour can be seen to be due to their efforts, then it seems reasonable to accept more credit for success than failure
Motivational explanation – Zuckerman (1979) argues the need to maintain self-esteem directly affects the attribution of task outcomes
The False Consensus Effect
Tendency for people to see own behaviour as typical & assume that others would do same under similar circumstances
o Ross et al. (1977) – asked students if they would agree to walk around campus for 30 mins wearing sandwich board saying ‘Eat at Joe’s’o Those who agreed estimated 62% of peers would agreeo Those who refused estimated 67% of peers would refuse
Explaining the false consensus effect
Cognitive Our own opinions are more salient to us &
displace consideration of alternatives We seek out company of similar others so
encounter more people with similar beliefs, interests etc. – experience inflated consensus
Motivational We subjectively justify the correctness of our
opinions by grounding them in exaggerated consensus – may enable stable perception of reality
Group-serving biases (Ultimate attribution error)
Tendency to attribute bad outgroup & good ingroup behaviour internally, & to attribute good outgroup & bad ingroup behaviour externally
Hewstone & Ward (1985) – study of majority malay & minority chinese ethnic groups in Malaysia Participants read stories that were either positive or negative
involving either ingroup or outgroup actor Malay group made internal attributions for positive ingroup
behaviour & external for negative ingroup behaviour, reverse for outgroup
However, chinese group made same pattern of responses i.e. favoured the outgroup
Hewstone & Ward explain this in terms of the particular nature of intergroup relations at this time
Explanations for group-serving bias
Cognitive - Social categorisation generates category-congruent
expectations (schemas, stereotypes) Behaviour that is consistent with stereotypes is attributed
to internal causes (e.g. Bell et al., 1976) If behaviour confirms expectation may rely on dispositions
implied by stereotype without considering other factors
Motivational – Need to obtain self-esteem from group membership by
comparing with other groups (social identity theory) Vested interest in maintaining ingroup profile that is more
positive than relevant outgroups
Explaining bias: motivation or cognition?
Early research apparently favoured ego-based explanations for bias
However, by manipulating info available, can modify biases implying information processing errors
But is social cognition really affect-free? Cognitive & motivational explanations are linked,
making it difficult to choose between the two Cognitive explanations actually contain motivational
aspects (Zuckerman, 1979) Motivational factors can have an effect on information
processing (cognition)
Effects of biases
Controversy over effects of biases Some argue our judgements are highly
erroneous – more errors in real life than the lab (Nisbett & Ross, 1980)
Others say we are generally accurate in judgements but lab set up to generate error (e.g. Funder, 1987)
Cognitive misers – people use least demanding cognitions to produce behaviour generally adaptive (Taylor, 1981)
Summary
Various biases affect social judgements/attributions: Fundamental attribution error Actor-observer differences Self-serving bias False consensus
Biases are probably the result of an interplay between cognitive and motivational factors
