Hindsight Bias

Hindsight bias, also known as the knew-it-all-along effect or creeping determinism, refers to the common tendency for people to perceive events that have already occurred as having been more predictable than they actually were before the events took place.

Pronunciation

Hindsight bias is pronounced as /ˈhaɪndˌsaɪt ˈbaɪəs/.

Etymology

The term "hindsight bias" comes from the two English words "hindsight" and "bias". "Hindsight" is a compound of "hind" (from Old English "hindan" meaning "from behind") and "sight" (from Old English "sihþ" meaning "thing seen"). "Bias" comes from the French "biais" meaning "slant, slope, oblique".

Definition

Hindsight bias is a psychological phenomenon in which people believe they knew the outcome of an event before it actually happened. This can lead to an oversimplification of cause and effect, and can affect decision-making processes, often causing errors.
