Primacy Effect

You're seeing it when investors make a mental decision within the first two minutes of a pitch and spend the remaining time confirming that initial impression. The opening framing — not the strongest argument — determines the outcome.

You're seeing it when an interviewer forms a strong opinion during the handshake and small talk, then interprets all subsequent answers through that initial frame. Strong candidates who start slowly get underrated; weak candidates who open well get overrated.

Design your pitch, product onboarding, and customer experience so the first moment is your strongest. The Primacy Effect means the opening frames everything — invest disproportionate effort in the first thirty seconds, the first screen, the first interaction.

Jobs was a master of the Primacy Effect, obsessively engineering first moments. Apple product launches opened with a single, arresting statement that framed everything to follow — "today Apple reinvents the phone" — ensuring the audience interpreted all subsequent details through the lens he'd set in the first ten seconds. Apple's packaging was designed to make unboxing a carefully sequenced first impression. Retail stores placed hero products at the entrance. Jobs understood that you don't get a second chance to set the cognitive frame. For founders, his approach demonstrates that the Primacy Effect isn't about tricks — it's about recognising that sequence is strategy, and that first contact disproportionately determines how your entire story is received.
