Behavioural Economics: Category Size Bias
11th December 2017
Here is a good example to use when discussing behavioural biases, specifically the problems people have in estimating probability and the exaggerated importance of category size when people estimate the chances of an event happening.
What is category size bias? It occurs when we are more influenced by options put into a relatively-large group.
Evolution is great, but it hasn't (yet) equipped us with the ability to judge probabilities. https://t.co/Qp7guyznMc pic.twitter.com/5eYt7Ry30q
