Nice discussion (and graphic) on the topic of cognitive bias

Hi all,

See the attachment; I am resending this to the list-serve in case there is anyone who hasn't previously seen it.

I came across this well-organized blog on the cognitive biases last October, and was very impressed with it.  The title is "Cognitive bias cheat sheet."  It provides a schema to organize the myriad cognitive biases which have been described in the literature, and puts them into a conceptual framework which helped me to make sense of this very complex topic.  I hadn't heard of the author - Buster Benson - before, but he is clearly a very organized thinker!  He points out that the many cognitive biases with which we struggle in diagnosis actually exist for particular reasons, and they can actually be adaptive under many circumstances.

Most of you have seen this before, and so I apologize for the duplication; but I thought it would be of interest for anyone who joined the SIDM list-serve recently, in helping us all to better understand a complex set of mental processes - our biases - which underlie a significant fraction of the diagnostic errors we are prone to make in practice.

All the best,
