If you are chronically spending every Saturday night alone, despite valiant and persistent effort to find a date, then chances are there’s something wrong with you, at least in this area of life. You probably don’t possess the qualities that members of the opposite sex seek in potential mates. Evolutionary psychological research has not only discovered what these traits are that men and women seek in each other, but also that the traits sought after by men and women are culturally universal; men everywhere in the world seek the same traits in women (such as youth and physical attractiveness) and women everywhere in the world seek the same traits in men (such as wealth and status). In fact, one of the themes of evolutionary psychology is that human nature is universal (or “species-typical”) and people are the same everywhere (or their cultural differences can be explained by the interaction of universal human nature and the local conditions). You may be comforted to know that you are not alone in your plight; there are losers like you everywhere in the world, and for the same reasons.
