Recently I have been reading about cognitive bias, a brief description of cognitive bias is : a pattern of deviation in judgement that happens in certain situations leading to irrationality.
I'm not going to go into it too much as Wikipedia is just over the page, but I was talking to an acquittance about this phenomenon to which she replied "I don't have any of those."
I love irony and I am just speechless at this statement as I'm certain that the denial of having any cognitive bias could in itself be a cognitive bias.
Thank you Irony.
