I feel that studies like this, while interesting, are just... stupid. They basically just took out the countless number of variables and complexity of attraction and narrowed it down to a few. Yeah, that's sort of the point when you are doing scientific research, but should scientific research really be the point here? What's this going to achieve? Sure, it's cool to know, people like to dissect things and find out how they tick, but I feel like with such a calculated, narrow, scientific method such as this, you aren't going to really get how it all works. This just has no relevance to my life.
