Groupthink
Core pattern
A group protects harmony, identity, or momentum at the expense of independent evaluation.
Ask: What dissent would be socially expensive to voice?

Groupthink vs Social Desirability Bias
Groupthink is a group decision dynamic that suppresses dissent; social desirability bias is distorted reporting caused by wanting to look acceptable.
Social desirability bias
Core pattern
People report what sounds acceptable, virtuous, loyal, or competent rather than what they actually think or do.
Ask: What answer is socially rewarded in this setting?
Why people mix them up
In meetings, people may privately disagree but publicly report agreement, so both can be active.
Quick rule
Ask whether the main distortion is convergence in group deliberation or self-presentational reporting.
Diagnostic questions
Use these before deciding which label should carry the lesson.
Is the distortion happening during deliberation, measurement, or both?
Would anonymous responses differ from public comments?
Did the group protect agreement before reasons were tested?
Mini cases
The same surface area can point to different underlying mechanisms.
Groupthink
A team avoids raising objections after a founder endorses a plan.
Why: Harmony is replacing independent evaluation.
Social desirability bias
Employees rate a disliked training highly on a nonanonymous survey.
Why: The reported opinion is shaped by acceptable self-presentation.
Repair Move
Change the process, then choose the label.
Use anonymous first-pass judgments, then give dissent an explicit protected role in the discussion.
