A while back (maybe 3-4 years?) there was a paper on common misconceptions of the genetics of various traits. One of them was eye colour in humans. I have lost this reference and can't find it anywhere. Does anyone recognise what I mean?

Looking without bias is very hard to do. We want to “let the data do the talking” but data must be interpreted against backgrounds that are not bias-free.
I want to tell you about an experiment showing how when looking at a plot, we come with bias that frames our perception.🧵⬇️
