Dating sites are female-driven, and females select primarily on looks, as has been shown on plenty-of-fish and tinder data analysis.

So a dating sites without pictures would never work. I hope to be proven wrong, but I don't think so.

Height and income seem to be important according to this okc study (based on millions of profiles):

I think the research you are referring to is about unconscious impact of looks on decision. Lack of pictures will affect choices, but will not necessarily make participants unhappy. The later requires an entirely different approach to be studied.

They select on looks because that's all they have on dating sites.

People (especially women in mainstream society) mostly ignore looks when they have already had a real-life pleasant interaction; however, it is very challenging to replicate that online, since it's very hard to give incentives to be genuine.

No women (and men) don’t. Looks matter. It’s eons of biology that’s too much to completely suppress. Looks always matter... but the degree can change.

The funny thing I noticed when living in Switzerland and traveling other European countries is due to the way lower obesity rate, most people are generally attractive.

The American obesity rate is something absurd like 40% among adults. A bunch of these people aren't actually half-bad looking if they were able to drop the weight.
