Group Attribution Error
- Filed under
- Not Enough Meaning
The charge
Group attribution error is assuming what is true of one member is true of the whole group, or that group-level traits cleanly describe each member.
How it operates
Categories compress variation and encourage people to slide too easily between individual-level and group-level inference.
Logged incidents
- Incident 01
One aggressive salesperson makes leadership say the entire regional team is pushy.
- Incident 02
A scandal at one portfolio company is taken as proof the accelerator is low quality.
- Incident 03

What to watch for
Ask: Am I moving from one person to the group, or from the group to one person, without enough evidence?
Recommended action
Sample across the group and perform an ecological-fallacy check before generalizing.
