Primacy Effect

The charge

The primacy effect is the tendency to remember items presented early in a sequence better than those in the middle. Early information often gets more rehearsal and becomes a reference point for what follows.

How it operates

First items have less competition and more opportunity to be encoded into long-term memory. They also shape interpretation of later items, which can further strengthen their remembered importance.

Logged incidents

1. Incident 01

   The first candidate interviewed sets the tone and is remembered unusually well compared with equally strong middle candidates.

2. Incident 02

   The opening framing in a pricing conversation dominates what a buyer later remembers about value.

3. Incident 03

   The first few customer quotes shown in a research readout disproportionately shape leadership's takeaway.

What to watch for

When early information feels unusually influential, pause. Ask: "Am I giving this weight because it came first or because it is truly the strongest evidence?"
