We notice when something has changed

Deep Dive

All Biases

Anchoring

We rely too heavily on the first piece of information we encounter (the "anchor") when making decisions.

Conservatism Bias

We insufficiently revise our beliefs when presented with new evidence.

Contrast Effect

We perceive things differently depending on what we've recently been exposed to for comparison.

Distinction Bias

We view two options as more different when evaluating them simultaneously than when evaluating them separately.

Focusing Effect

We place too much importance on one aspect of an event, causing errors in predicting future outcomes.

Framing Effect

We draw different conclusions from the same information depending on how it's presented.

Money Illusion

We think of currency in nominal rather than real (inflation-adjusted) terms.

Weber–Fechner Law

We perceive changes in stimuli proportionally to their initial magnitude (a small change in a large stimulus is less noticeable).
