While this study focused on same-sex meetings, Ramirez said it could have applications for dating as well. For one, the study suggests that speed dating -- in which you have very short, timed ''mini-dates'' with a variety of people in one evening -- may have real value. While some people have questioned whether you can really evaluate a potential date in just a few minutes, he said this study suggests people already do that.
''Romantic relationships probably are similar to what we found in this study -- they begin with people making judgments very quickly,'' Ramirez said. ''We would like to study that in the future.''"
