"Girls in a research lab are quite possibly wearing less makeup"
Well I think that's my point. The girls in the club put in quite a lot of effort in makeup and dress, and are tottering around in high heels, to make themselves more attractive. (I've seen girls put themselves through comical levels of suffering merely for the sake of wearing heels.)
The girls in the research lab are probably instead putting that effort into reading research papers to make themselves better informed. They may well be wearing lab safety gear.
"It's entirely possible you're looking at the same set of girls"
Maybe, somehow I doubt researchers have the time to get out of lab though.
