UPDATE: I did not realise this was from 2015. Sorry!
Amongst other questions they were asked how they would act in a situation where they could have sexual intercourse with a woman against her will “if nobody would ever know and there wouldn’t be any consequences”. 31.7% of all men participating in the study would force a woman to have sexual intercourse in such a “consequence-free situation” – which is rape.
Worryingly, most men who indicated that they would commit rape did not even recognise their actions as such.
When explicitly asked whether they would rape a woman if there were no consequences, only 13.6% of participants said they would do so, a marked fall on those who had described that they would commit rape.
From here.
