Choice Architecture - When the environment in which someone must make a decision has been carefully designed to try and influence that decision

Hindsight bias - Tendency to see events in the past as having been predictable

Sunk cost bias - Tendency to continue a behaviour as result of previously invested resources (such as time, money or effort)

System 2 thinking = Decision making that is slow, controlled, considered and conscious

Habit - A rigid pattern of behaviour

Default choice - Option that a consumer selects if he or she does nothing

Herd behaviour - Phenomenon in which individuals act collectively as part of a group

Endowment effect - People tend to value things they own more than others value them

Gambler's Fallacy - Mistaken belief held by some people that independent events are interrelated

In this revision video we look at some of the cognitive biases that can affect people’s behaviour. ​The existence of such biases calls into question economic models that assume people always act rationally, attempting to maximise their individual self-interest. ​​

Behavioural economics is the topic area we focus on this live revision session for A-Level Economics students.
