R.B. Zajonc

Feeling can come before thought.

Polish-born American social psychologist known for the mere-exposure effect, social facilitation and the primacy of affect.

Preferences can arise before conscious inference.
— R.B. Zajonc

Who they were

Robert Zajonc showed how much of liking runs ahead of reasoning. Simply seeing something often makes us prefer it, and the presence of others reshapes how we perform. His most provocative claim was that affect can come first — we may feel before we have had time to think.

Their big idea

Mere Exposure & Affective Primacy

Robert Zajonc demonstrated that repeated exposure to a stimulus increases liking for it, and argued for affective primacy: emotional preferences can form before, and independently of, conscious cognitive evaluation.
