While researchers have taken steps to comprehensively catalogue the preferences of men and women, we still don't know which traits are the most important contributors to a person's attractiveness. What we do know is that not all attractive traits are preferred equally. This can be revealed using some basic psychological tasks, such as asking people to design a partner by allocating points to enhance their characteristics (similar to designing a character in a video game).

When given only a small points budget, tough choices have to be made – and some characteristics normally attractive in their own right tend to fade into the background. One study found that creativity and talents were trumped by the likes of intelligence and social status during the task. Interestingly, basic kindness tends to be one of the top traits when building the ideal long-term partner.
