Loss Aversion (Why do we fear losing more than we enjoy winning?)
Loss aversion, a brief explanation
What is the Loss Aversion?
The loss aversion is the tendency to fear losing more than enjoying winning or gaining something new.

Examples
Making a relatively ‘sage’ low return investment over a potentially lucrative new investment that carries risk.
Purchasing flood insurance for a property on high ground where there is no risk of flooding. The fear of losing property as a result of flooding can drive people to purchase such insurance.
