Cognitive biases in meetings
The bandwagon effect, authority bias, and anchoring distort meetings most: a few early voices create false consensus, the senior person's view carries regardless of merit, and the first proposal frames everything after. Spotting them keeps a room from mistaking momentum and rank for good decisions.
The ones that bite hardest: Bandwagon effect, Authority bias, Anchoring bias.
The biases, and how each one bites
- Bandwagon effect
Once a few voice support, the rest converge on the emerging consensus, mistaking momentum for agreement.
- Authority bias
The most senior person's view carries the room regardless of merit, so juniors defer to the title.
- Anchoring bias
The first number or proposal anchors the discussion; every later option is judged relative to it.
- Halo effect
A confident, well-liked speaker makes their idea sound better, letting one good impression carry a weak proposal.
- Primacy effect
Whoever speaks first or tops the agenda frames the debate; later contributions struggle to shift it.
- False-consensus effect
You read silence as agreement, so real objections never surface and get mistaken for buy-in.
- Confirmation bias
People arrive with a preferred conclusion and steer discussion toward supporting evidence, dismissing counterpoints as noise.
- The curse of knowledge
The expert presenting can't imagine what others don't know, so briefings skip context and the room nods along.
- Recency bias
The last point raised before a decision weighs heaviest, so speaking last can outweigh substance.
- Action bias
Under time pressure the room favors deciding something over waiting, even when more information would help.
