Boiling Down Personality Matching

Meeting people you get along with is a bit of a conundrum, even with our super-connected society. So I’m wondering, can we boil down personality to 3 questions?

Sure, DiSC and MBTI can give you a good idea of what your personality is like with quite a few questions, and even sites like eHarmony have ways to match people who are dating (258 questions). A friend of mine started a great project, Roommatefit,  that matches roommates for colleges. I asked if he could keep me in the loop as his questions evolve.

But how accurate and predictable of “getting along” can a 3 question system be? Have you ever heard of or seen a personality-matching system so short? I’ve been searching, and so far: nothing.
