I saw this in the NY Times… and here is says from the WSJ but in any event, the word is out. Math wizzes are human. The human brain does funny things with biases and predispositions that causes it to not see the data clearly.
In fact, one solution to this is to always assume that we are being biased and where the bias is and how can it hurt us? Where is the emotional attachment to the current “viewpoint” and how can that be a risk?
THAT is part of psych cap and the coming paradigm for comprehensive risk management.
