The charge
We remember and often value ideas more when we generate them ourselves rather than simply receive them.
How it operates
Producing an answer creates deeper encoding and a sense of ownership, which can spill over into preference and confidence.
Logged incidents
- Incident 01
A team overweights a brainstormed feature over a user-requested fix.
- Incident 02
An interviewer prefers a candidate they 'discovered' themselves through sourcing.
- Incident 03
An executive trusts a strategy more after sketching it personally on a whiteboard.
What to watch for
It shows up when internally generated ideas feel stronger before evidence is compared. Ask: 'Would I like this just as much if it came from outside the team?'
Recommended action
Blind-review ideas where possible and evaluate them with the same rubric regardless of origin.
