Was reading a summary of Everybody Lies by Davidowitz who was a data scientist at Google. His data mining of Google searches is supposed to reveal people's real desires vs. what they claim. Some findings (to be taken with a grain of salt):

  1. Many men are more attracted to overweight women but pursue skinny women, because that's what they think they should to impress others

  2. Gay men number about 5% of population

  3. About 20% of porn that women watch is lesbian porn (though it is not clear if more lesbians watch porn compared to straight women).

  4. People lie/exaggerate about the amount of sex they have
