I think it probably also depends on what the hazing entails - making the newbys complete some miserable gruelling physical activity followed by everyone getting drunk together - probably pretty damn good bonding. The new people have done something unpleasant and demonstrated a level of commitment to the cause, and then everyone has cut loose together showing some vulnerability (from intoxication) within each others company - that really will bond people.
If your hazing is forcing new people to get really drunk and then sexual abusing them (which is what a lot of American college hazings seem to be)- I don’t think that’s good (on any level). It may have some bonding affect for the perpetrators but for the victims? I’m not sure. Maybe when they turn perpetrators the following year they would get a delayed bonding affect? Either way that’s not good.
Going bowling doesn’t take any level of commitment from the participant though - it’s just a nice thing to do - they’d do that anyway. The bonding part comes from doing something unpleasant to show commitment to the group. I’m not saying the weird shit that it has developed into on campuses is a good thing, that’s way too far. But I was a member of a running club and to be a full member you had to run on a summer Saturday across a set route up and down hills repeatedly just the hardship and over difficult terrain in the heat of the day - it was a long and deeply unpleasant run. But then all the new runners and all the existing members have a big bbq and eat food and drink cold beers together. The old timers congratulate you on your performance and reminisce about when they did it - perhaps it was a heatwave back in ‘92 or there was flooding or whatever. Everyone winces together when they see the size of that guys blisters etc. and just like that you’re bonded. You’ve all had a shared experience of a trial you completed to be part of the group. Hazing like that is a really good experience.
