Q

Group function

Hill (1982)

A

Evidence of process loss and process gain

Process gain- through process of group discussion- get right answer

Process loss- acting crowds hinders ability to get right answer

Groups performed at accuracy of second best member

2
Q

Why comparing groups is hard

Task type

A

Intellective (involves reasoning) vs judgement task

Well defined (clear success metric) vs ill defined

Required insight

Required background knowledge

Provoke strong intuitions or emotions

3
Q

Why comparing groups is hard

Standards of comparison

A

Consider where people are individually on performance

Synergy- collaboration group performance is better than best individual

4
Q

Why comparing groups is hard

Coordination methods

A

Averaging- just collect ppts individual answers and no discussion

Iterative- everyone gives answers, sees answers of other people and get to change

Pick best individual answer-> dictator method- group decides who they think will be the best person to answer

5
Q

Why comparing groups is hard

Individual differences

A

Do they have different sources of info- access to cues

Do they differ in ability

In other capacities

6
Q

Gigone and Hastie

1997

A

Lens model

Never really see the world just given cues that tell us how to see it/ construct representation of it

Various cues we can pay attention to, come to different judgements by cues- combined in group judgement

Revision- what someone else says changes own judgement

7
Q

Errors

A

Independent estimates- not influenced by other judgements

Uncorrelated errors- more judgements can get better estimate of true value and can get rid of noise

Correlated errors due to: limited info, individual bias, group conformity

No systematic biases

No coordination between group members

8
Q

Group think

A

Polarisation in group decision making

Group become obsessed in single view answer

Overconfident that it’s right

Blindness to errors

Due to conformity

9

Social account of reason

A

Interactionist account- reason evolved to produce and evaluate arguments

Primary reason to create arguments is to persuade other people

10
Q

Wason task in small groups

A

Normally 80% fail

In groups 80% get right answer

Truth wins scenario- someone gets right answer and manages to persuade everyone in the group

11
Q

How groups reason

A

Exchange of arguments

Groups typically co constructed a structure of arguments qualitatively more sophisticated than that generated by most people - justify beliefs

Show synergy

12
Q

Collective intelligence

A

G- inspired by idea of general intelligence

C- collective intelligence

Does the general intelligence (individual) after the collective intelligence (group)

13
Q

Predictors of group intelligence

A

Average social sensitivity

Amount of communication

Distribution of communication

Coordination problem of group work often overweight the intellectual intelligence

Higher social perceptiveness (RME)= better group discussion
