However over the a long time, the work of Herbert Simon, Daniel Kahneman, Amos Tversky, Robert J. Shiller, and Richard H. Thaler, amongst others, challenged this orthodoxy and demonstrated that market and investor habits are sometimes far more ambiguous than these theories would counsel.

However on the very least, as this assortment demonstrates, viewing typical finance by means of a behavioral lens can yield important perception.
