People may suck at knowing what they want, but I think it's more that people do not necessarily know what criteria they should want to select given their goals for finding someone.
Another problem is that a lot of users are probably more casual about the weights, such as selecting mandatory. (It's common for people to select an answer and then mark that same answer as unacceptable in a match, for questions in which it makes no sense for them to do that.)
