Maybe because they make a really good first impression and come across as more attractive and charming. They put more effort into their appearance too, generally, and give the impression they have high sexual prowess. It's mostly surface and the charm fades..

Research says it's something to do with the ‘dark’ personality traits such as narcissism, psychopathy, and Machiavellianism—otherwise known as the ‘dark triad’ of personality traits.

Because in the whole history of humankind, nobody's asked this question so they have to conduct important research... Oh oops, not one of the "ladies" xD
For a somewhat fresh perspective, I think it'd be good if people looked at what kind of people women DON'T go for, and also that most of the "bad boy" behavior provides a direct advantage into actually approaching women.
While all generalization is always bad, it's also interesting to not that while clearly some prostitution is driven by convenience or desire for variety and excitement, MOST prostitution would disappear overnight if it actually were the case that "there's someone for everybody" (Not to equate sex and love, but one usually follows the other in relationships).

They give the illusion they’d be good in bed I think

I think you know what you are getting, "nice guys" are seldom nice in my books.

Some ?
All girls are attracted to bad boys .
Which said , truth is very few want to take risk having relationship with a bad boy ..
Cause afterall he is a BAD boy .
Actually most females prefer a partner who is masculine, is active in occasional physical fights : a symbol of masculanity , exhibits a sense of dominance over her and feels possessive for her like she is his territory ..and at the same time most bad boys pretend they dont give a damn about girls and their feelings and this playing HARD TO GET is most of time successful even in case when the girl is playing hard to get ..but there is always a limit of dominance , hard to get , possessiveness ,violence - anger , jealousy and when the limit crosses line , girl feels suffocated , abused and trash and all attraction vanishes completely .

Analogy is - why people prefer to abuse ? Say things like fuck off , etc .
Because it looks cool but at a certain point the vulgarity becomes too much and it no longer appeals .

It feels good to be bad now and then.

Confidence I would guess

The good guys don't seem to know how to go after the woman. We like the chase ad the good guys seldom chase us.
