Mere Exposure Effect

The tendency to develop a preference for things simply because you are familiar with them.

Familiarity signals safety — if something hasn't harmed you before, it's probably safe. This creates a positive association with repeated exposure, even without any conscious evaluation.

• Preferring a song you initially disliked after hearing it multiple times.
• Choosing a familiar brand over an unknown one, even without evidence of better quality.
• Feeling more comfortable around people you see regularly, even without interacting.

• Be aware that familiarity ≠ quality.
• Deliberately try new things to counteract the comfort of the familiar.
• In decisions, ask: 'Do I prefer this because it's better, or because I'm used to it?'
• Use this effect positively: expose yourself repeatedly to things you want to learn or appreciate.
