Biased Sampling

Occurs when the discussion is dominated by information that the group already knows, while information that the group does not know is not shared.

The c'''onsequence of biased sampling is bad decisions are made because the group does not have the information it needs. '''

Cause: When people are unaware that not everyone has access to necessary information.

Aids and fixes:


 * A group leader who encourages lots of participation.
 * Groups gaining experience are more often going to share information with one another.
 * Priming members to think counter-factually (imagine alternative outcomes to things that could have happened but did not).
 * Delegate information into smaller portions by matching information to individuals based off the individuals’ expertise and interest.
 * Use transactive memory which is a shared system for remembering information and sharing information.
 * Groups with critical thinking norms are more likely to discuss unshared information
 * Have specific, challenging, and reachable goals
 * Welcome interventions that alter the natural flow of behavior in the group and challenge the group to think in novel ways about procedure.
