What you need to know about favourite-longshot bias.

With favourite-longshot bias, bettors experience two different attitudes towards risk; risk aversion toward the favourite and risk seeking towards the long shot. This can seem as though it defies logic – why would you place a bet on the least likely candidate to win? The thought of the return can't be the sole factor in these decisions.
