<p>I've spent a lot of time in a lot of the dorms, the following are my observations and should be taken with a grain of salt.</p>
<p>Baker: Lots of people. Lots of social people. Nothing too distinguishing, and that seems to be a sort of appeal. You might forget you're in an MIT dorm (until it gets late and people have to do psets). Parties revolve heavily, heavily, on alcohol. </p>
<p>Burton-Conner: Similar to Baker, this dorm possesses a lot of "normal" people. Geeky, suite-based cultures are definitely present. Houses one of MIT's most infamous party halls: Burton 3. I like a lot of the people I've met from BC, but it varies with each hall, as you'd expect. Less homogeneous than, say, Baker. </p>
<p>East Campus: These are those crazy guys who make big explosions for everyone to enjoy. EC is full of engineers and course 6, though that's far from all you'll find there. Culture varies drastically from hall to hall, but is generally more "free" than what you'd find in other dorms. Lots of freedom to modify your dorm room. </p>
<p>MacGregor: If there's any dorm it's hard to speak generally about, it's MacGregor. This is mostly due to the way it's broken up: into several groups of floors called "entries," which share common areas. It has a reputation for being the "anti-social" dorm, and for sure, some of the entries are quite anti-social, while others closer to Baker and yet others closer to Senior House.</p>
<p>McCormick: The all girls dorm. Nice location on campus. Dorm is like a freaking hotel... extraordinarily nice. Most of the girls there are your average MIT girls. To be fair, a some girls end up in McCormick because their parents impose it as a condition on them going to MIT, but then there are a lot of girls who are plain unwilling to live near guys. I don't know enough about dorm culture to comment beyond that.</p>
<p>New House: Holds the "cultural houses" and therefore has a lot of international students, but don't expect to interact with them often. Each of the 9 "Houses" in New House tends to keep to itself, and I don't know enough of the house culture to comment beyond that. I went to a party there, and it was pretty horrible.</p>
<p>Next House: the only dorm I know nothing about. Furthest away from everything, residence based advising (ew). A lot of my friends at Next felt "trapped" in the RBA program (you can't switch out). This will change next year. Go check it out for yourself, for me, it wasn't worth the walk.</p>
<p>Random Hall: EC's younger, nerdier, perhaps socially awkward sibling. Good people who often do awesome things. The vast majority of the dorm does EECS or Math. Definitely for some people, and not others. When you think of your stereotypical MIT "nerd", you're probably imagining some combination of Randomites. Also the smallest dorm... very tight communities.</p>
<p>Senior House: Key word is freedom. Senior House functions under a sort of paradise law. You can do pretty much whatever you want, and others can do the same. It's a delicate balance between doing what you want and keeping the interests of your peers in mind. If something bothers you, you tell that person to stop, and they probably will. But if you live in Senior House, most things shouldn't bother you. Freedom also means if you're a jerk you can expect someone to urinate on your door. Don't be a jerk.</p>
<p>Simmons: the space sponge. A really, really, young dorm. Doesn't have a culture yet. I haven't spent much time there but I do have a lot of friends living there. It's an odd amalgamation of cross-campus culture that varies depending on the part of the dorm you're in. Because of the way it's broken up, you may not have much contact with many of the people in the dorm, especially not outside the same "tower."</p>
