mere_exposure_effect
The mere exposure effect is the psychological phenomenon where people develop a preference for things simply because they are familiar with them, even without any conscious recognition of prior exposure. Repeated exposure to a stimulus increases positive affect toward it, and this effect operates below the threshold of conscious awareness.
A consumer consistently chooses a particular brand of cereal not because of taste tests or reviews, but simply because they have seen its packaging hundreds of times on store shelves and in advertisements, creating an unconscious familiarity preference.
During an election campaign, a candidate with modest credentials but a massive billboard and social media advertising budget consistently polls higher than a more qualified opponent with less visibility. Many voters, when asked why they prefer the first candidate, simply say the name 'feels familiar' and 'trustworthy.'
A new employee initially finds a colleague's unconventional communication style slightly off-putting, but after working alongside them for several months without any negative incidents, begins to genuinely like and trust them — not because of any particular positive interaction, but simply due to repeated, neutral exposure.
Binary (yes/no) questions an LLM must answer to identify this aspect:
Is a preference driven by familiarity rather than objective merit?
Type: binaryHas repeated exposure to something increased its perceived value?
Type: binaryWould a novel alternative be preferred if exposure were equal?

Familiar stimuli are processed more fluently (with less cognitive effort), and the brain interprets this processing ease as a positive signal - confusing 'easy to process' with 'good' or 'safe.' Evolutionarily, familiar things that have not caused harm are indeed safer.
When noticing a preference, ask whether it is based on genuine quality assessment or simply familiarity. Force yourself to try unfamiliar alternatives periodically to ensure your preferences are based on actual merit.
The mere exposure effect is fundamental to advertising (brand recognition drives preference), political campaigns (name recognition predicts voting), and music preferences (songs grow on listeners through repeated play).
