Condom Use
Turns out young people overestimate how often they use condoms when having sex. The study’s sample was restricted to young people, but it’s not hard to imagine this finding holding true across all ages. People chronically — perhaps constitutionally — slant their conceptions towards what they consider favorable. For instance, a good rule of thumb for estimating how many calories you consumed in a given day is to make a guess…and then add 40%. Not only do folks overestimate how often they use condoms but they underestimate how much they eat.
