Mere Exposure Effect – when you like something just because it’s familiar

Have you noticed that the more you see something, the more you like it? That’s Mere Exposure Effect – the tendency to prefer things just because they are familiar.
Where it can show up
- Advertising & brands – the more you see a logo or slogan, the more trustworthy it seems.
- Music & culture – a song you disliked at first suddenly becomes your favorite after hearing it a few times.
- People & relationships – a colleague or acquaintance seems more likable simply because you see them often.
A practical countermeasure
- Recognize the power of exposure – just because you’re used to something doesn’t mean it’s the best option.
- Don’t mistake familiarity for quality – evaluate things objectively, not just based on how often you encounter them.
- Expand your choices – try new products, music, and connections to avoid getting stuck in the exposure trap.
