Are some romantic relationships fated to fail for the very characteristics that brought the couple together in the first place? New research by a UC Davis sociologist suggests so. In fact, a relationship may be doomed from the start when dating partners are chosen for traits that will subsequently be disliked, says Diane Felmlee, associate professor of sociology who presented her findings at a recent conference. Qualities most likely to result in "fatal attractions" included "exciting," "spontaneous," "fun" and "competent." Less risky attracting traits included physical characteristics and openness. The research suggests people may have more control over their romantic destinies than they realize, Felmlee says. She studied more than 300 college students, asking about their most recently ended dating relationship. Among qualities later disliked were selfishness, insecurity and undependability, with men and women in agreement. As for attractive qualities that withstood the test of time? Looks led the list.
