Because we're really good at fooling ourselves, and we lie to present an idealised version of ourselves.

Example: [Apparently] having coffee in the morning doesn't wake you up, it's that caffeine dependency (and maybe a little dehydration) makes you feel terrible. Coffee temporarily reverse this negative [local maxima].

Coffee appears to wake you up, but it's doing the opposite.

There are many common examples - 'drinking doesn't affect my driving', 'I don't drink heavily', 'advertising doesn't affect me', 'I get enough exercise', 'my diet is healthy', 'I go to church regularly'.

Reports here https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5639921/#!po=7...., for example, have measured overreporting of exercise/church attendance at double.
