The charge
We tend to like things more after repeated exposure, even when the repetition provides no new value. Familiarity itself breeds preference.
How it operates
Repeated exposure lowers uncertainty and increases perceptual fluency, which is experienced as liking. The effect is strongest when exposure is noticed lightly rather than scrutinized heavily.
Logged incidents
- Incident 01
A team prefers the incumbent vendor in a procurement review largely because they have seen that brand for years.
- Incident 02
A candidate who has met more stakeholders feels like the better fit even when rubric scores are similar.
- Incident 03
Users rate an interface more positively after seeing it repeatedly in demos, before they have actually used it to do real work.
What to watch for
Ask yourself: 'Do I like this more because it is genuinely better, or because it is the option I have seen most often?'
Recommended action
Use blind evaluation and precommitted scoring criteria before repeated demos or repeated meetings sway preference. Counterbalancing exposure order is the experimental-control version of this idea.
