One nagging thing that I still don’t understand about myself is why I often succumb to well-documented psychological biases, even though I’m acutely aware of these biases. One example is my failure at affective forecasting, such as believing that I will be happy for a long time after some accomplishment (e.g. publishing a new book), when in fact the happiness dissipates more quickly than anticipated.

Another is succumbing to the male sexual overperception bias, misperceiving a woman’s friendliness as sexual interest. A third is undue optimism about how quickly I can complete work projects, despite many years of experience in underestimating the time actually required.

One would think that explicit knowledge of these well-documented psychological biases and years of experience with them would allow a person to cognitively override the biases. But they don’t.
