Okay, after reading this thread, I feel the need to respond to set the record straight about this issue. I want to make sure that LGBT applicants everywhere know how to handle this issue and aren't riddled with the misinformation found in this thread.
I went to an open-house event exclusively for LGBT students at HBS a few months back, so we literally got an entire day to ask questions about all of this stuff. Let me tell you the gist of what the admissions office said at HBS:
1. Yes, schools love diversity. Therefore, schools do appreciate having people who identify as LGBT within the student body. There is a reason that HBS had an entire open house ONLY for LGBT students - HBS wants LGBT people.. That being said...
2. At a school that is both as highly-ranked and large (in terms of class size) as HBS, disclosing that you are part of the LGBT community doesn't really help you all that much. Since much of the LGBT population is quite talented, driven, and personable, a lot of LGBT students will end up at the top schools. You are bound to be other classmates who are part of the LGBT community.
3. Some people choose to disclose their sexuality on their applications, but others don't. There are a few ways to do this:
- Include it in an essay. Only do this if it something that you're actually passionate about (i.e. a lawyer who fights for LGBT rights, a personal experience that shaped you, etc.) -- don't just throw it in for the "bonus points."
- Include it somehow within your list of college activities and clubs (i.e. a Queer-Alliance type of club)
- Reach out to members of the LGBT student association at the school you are applying to.
That's really it. Please ask if you have any questions.
To clarify a few other points:
1. I can't think of a reason that anyone would "pretend" to be a part of the LGBT community. As stated above, the potential benefits aren't really that great in terms of admissions since there are so many LGBT people who are unbelievably competitive applicants. The potential consequences can be severe, as pretending to be something that you're not is a painful experience. Beyond that, who would honestly want to deal with the ridicule that the LGBT community faces?
2. I am a guy who has a long-term girlfriend, but I still identify as part of the LGBT community. That does not mean that I am faking anything; sexuality lies on a spectrum for many people. We can continue this part of the discussion in the off-topic forum if you have any questions.
