Mere Exposure Effect
Play a stranger an unfamiliar tune once, and it is noise. Play it ten times, and it becomes likeable. No persuasion occurred. Repetition alone manufactured the preference — we come to like what we have merely met before.
The machinery is safety. For a cautious creature, the unfamiliar is potentially dangerous and the familiar has already proven survivable. Familiarity is the mind's shorthand for "has not killed me yet."
This quietly governs more of life than taste in music. The candidate whose face has been seen wins votes. The brand merely remembered wins the shelf. The opinion heard repeatedly starts to sound like common sense — truth by attendance.
Two disciplines follow. As a citizen of your own mind: when something feels right mainly because it is familiar, ask whether it has any other qualification. And as someone who must persuade: do not argue first. Show up, repeatedly, calmly, inoffensively. Liking is built by presence long before it is built by reasons.
