Brief thoughts on biases

Cognitive biases are all the rage in intellectual discourse, especially since the publication of Thinking, Fast And Slow.

Recent on Twitter I came across this tweet:

Not only is the diagram “beautiful if terrifying”, but the accompanying article at the link is a terrific overview of biases. It also makes the point very clearly that biases are tools – and are responses to problems. Much of the discourse around bias makes them sound like unmixed evils and realising they are in fact approaches to the world that help up survive and (possibly) thrive, with the potential to mislead also, is important.


I have been contemplating a longer piece on bias, and the role of bias-discourse in contemporary debates (especially online) Bias-hunting has become a bit like the Popperian view of Marxism and Freudianism – an approach that explains everything. There are so many biases that everyone and every assertion can be accused of possessing at least one.

This is something I wish to expand on at some point. Bias discourse is very prevalent in the medical literature – this is broadly to be welcomed. Yet I am suspicious (this is perhaps a bias of some kind) that bias discourse can be misused to shut down debates and dialogues, and that some of the proposed solutions – “metacognition”, the scientific method (reified to an uncomfortable degree) – are themselves prone to bias.
