I had a job for seven years where most of my colleages were INTP's. While that really wasn't that great, I know that being locked up with INTP's would not be the hardest part. The things I really have questions are
1) bathroom. I didn't see any mention of it. You know in the Stanford Prison Experiment they had then crapping in the corner near the end. That is a far bigger deal than whether or not the other people are INTP's.
2) fresh air. Even if the bathroom situation is ok, there is a matter of fresh air. If that air gets stale after a while then I think I'll get sick just from that. (And of course if there is no ventillation at all then I'll die.)

I just spent a long weekend with two female intp's, one being my sister. Really it was absolutely fine. I did find myself being pulled up a lot on various topics of discussion but i held my own... a few more hugs and giggles wouldn't have gone amiss.
Over all a lovely relaxing weekend...and great to see my Lil Sis.

I'm willing to invite 10 INTPs over to hang out at my house- there's plenty of windows, and I can cook for them!
Well, if you insert free home-cooked food into the equation, I'm there!
Really, I think I'd probably do just fine with 10 INTP's. Might get a bit boring, but most INTP's would probably be okay with leaving each other alone to read, more or less. But I don't think I could be in an enclosed space with any 10 people for more than a few days, without going a bit stir-crazy.
