<p>This was very helpful to me. I will keep the author anonymous, but they are very thorough, and I observed similar circumstances:</p>
<p>"Here is a breakdown of the fraternities that I’ve observed. I’m going to group them in tiers of most fratty to least fratty, based on the stereotypical stereotype of frattiness -</p>
<p>Most Fratty</p>
<p>Chi Phi - Very rich, quite a few internationals and Europeans
Delta Tau Delta - Lots of people from California, into alternative and electronic music
Delta Upsilon - Water Polo players
Lamda Chi Alpha - Basketball players
Sigma Chi - Similar to Chi Phi, but a lot more white and America, versus Europeans and a minority of Indians and stuff</p>
<p>A little less fratty</p>
<p>Delta Kappa Epsilon? (DKE) - A lot of football players, but they seem more quiet and not really as fratty as one might expect
Kappa Sigma - Overall, pretty athletic but not necessarily centered around one sport. Possibly they are more into intramurals
Phi Beta Epsilon - Lots of Asians and Indians, lots of course 6, they’re the type to work hard and party hard, and they’re pretty into themselves. A small minority is track players.
Phi Delta Theta - Don’t know too much about them, I think they’re pretty diverse but kind of generic, with quite a few people in MIT’s dancetroupe
Phi Kappa Theta - A lot of asian, and a slightly tamer version of PBE, but they’re not into themselves at all
Phi Sigma Kappa - A tamer version of Chi Phi, they are a lot more chill though, not as full of themselves and have a pretty tame pledge program, they hang out with girls from A Phi a lot (the most stereotypical sorority) since they live right next door
Sigma Alpha Epsilon - I think they have a house now, but I don’t know if they throw a lot of parties. They have a lot of track players.</p>
<p>Not so fratty</p>
<p>Nu Delta - Black
Phi Kappa Sigma - Kind of like a tamer version of Phi Sigma Kappa.
Pi Lambda Phi - A lot of asians, kind of like a tamer version of PBE.
Sigma Nu - Don’t know too much about them
Theta Chi - Don’t know too much about them
Theta Delta Chi? (TDC) - Hispanic
Theta Xi - Don’t know too much about them, I think they’re less nerdy than they might have been in recent years
Zeta Psi - Basically a tamer version of Kappa Sigma</p>
<p>Not fratty at all - </p>
<p>Alpha Delta Phi? (ADP) - Pretty nerdy, they play video games a lot, but they still throw parties and stuff
Sigma Epsilon - They just re-colonized a few years ago, so they aren’t crazy like they were in the 90s.
Tau Epsilon Phi? (TeP) - A weirder version of East Campus and Random. Probably should be an ILG instead
Zeta Beta Tau - It’s far away and in Brookline, pretty academic, they’re the type to play board games for fun"</p>
