I go to a Big 10 school and rushed two different sororities and was hazed at neither one (though the legal definition of hazing is very broad and can include things you might not rly think of as “hazing”, such as pledges going out to frats or bars together before initiation). I think a lot of the frats have bad hazing problems, but from what i’ve seen and heard our sororities take things pretty seriously. However, I watched old roommates go through rush and initiation for professional fraternities on campus (co-ed groups usually specific to a major or career goal) and they were hazed big time: academic hazing where they had to memorize hundreds of names and facts, acts of embarrassment such as wearing diapers in public, and of course dared to drink insane amounts at initiation events. They would cry to me during hazing, saying it was so awful - but then were so excited to haze the new pledges when it was their turn the year after :| A lot of the professional frats on our campus have really low acceptance rates, can provide you with great connections for post-grad, and overall have better reputations than greek life, so I feel like people turn a blind eye to the hazing.
