Quote of the Day

Being open about uncertainty is not just a case of reporting some kind of statistically-derived “margin of error”. There are many ways for a conclusion to look statistically robust but be wrong. What is needed is to be clear about the underpinning assumptions and open-minded about what would happen if the assumptions were mistaken.


It is not clear why we enjoy certitude so much – certitude being the subjective experience of feeling certain. In contrast – as Kathryn Schulz observes in her wonderful book Being Wrong – there is simply no psychological experience of “being wrong” at all, only the lurching realisation of having been wrong until a moment ago.
