Reversion to the mean is the iron law of the financial markets - John C. Bogle

Post this crisis - Will this law apply to human psychology as well or will we see a dramatic shift in human behaviour ?

Behavioural Economics have taught us that for market to be efficient the market participants have to act rational all the time but history has proven time and again that stock markets are far from efficient as humans seldom act rational due to various cognitive & emotional biases

Below is a great thread for the potential changes in human behaviour & social norms we might see post this crisis - https://twitter.com/rahiljasani/status/1245032071581429760

In the interim the said potential changes seem rational to us but will they become a social norm post the crisis ends ? It will be very interesting to see if humans adopt this new behaviour permanently or revert back to the mean.
