It is common knowledge in the Manosphere that women extensively use preselection to choose which fellas to target. That is, they look for men that are presently getting lots of attention presently from women and/or did so in the past. The objective of this is to find the best men in order to satisfy their hypergamy.
In reality, this is really a crowdsourcing technique, where the knowledge is gleaned from the fact that other women are paying attention to a given man. This crowdsourcing is very much a shortcut to gaining knowledge, as digging out information by yourself can be time-consuming with much effort wasted. Of course, gathering the information for yourself very well might result in better information being obtained, but would it be worth it? If you were a rational lady looking for a compatible long term partner, then the answer could very well be yes. If you are looking just to satisfy your hypergamic itch, then perhaps not.
Actually it is not so surprising that women engage in this behavior; as humans in general regularly engage in it. People follow the latest fad, because everybody is doing it. Once again, it is a shortcut for actually gathering info and thinking. Unfortunately there are often not enough people who suggest that maybe the Emperor has no clothes.
As for the fellas, the first test that women need to pass is based on appearance. It does not really matter what other fellas think about a particular woman; what matter is what he thinks about her. Once passed that hurdle; either the fella can go in for the score or decide to gather more info to see if she is worth an LTR. Note that there is no hypergamy driving anything here, so it is less imperative to find some type of best.
