A new survey lists the top ten American cities by how often people in those towns have sex. Houston came in number one, if you care. How was the survey done? By handing out questionaires to 100 people at random in each city. The survey, done by a condom manufacturer, had no way of verifying the information, so the data doesn’t show how often those people have sex — it shows how often those people say they have sex. What are the chances those people were honest in their answers? Would you be?
