Here are six INTP Profiles I've bumped into:

• INTP Profile (2) is a new find (10/2002), not too long but touches nicely on some relevant attributes.
• INTP Profile (3) is uncanny! It's me all the way, except I don't have a good memory (which in turn also undermines the nostalgia thing), and my research (cybernetic epistemology) has given me a very different view on emotions than is described there. (Also, I don't recognize any of those composers, so I can't say whether it matches my music tastes.) Otherwise, read that and you'll have a much better idea of who I am (if you care).
• INTP Profile (4) is also very accurate. The relationships and career links at the bottom are also pretty applicable. Also off that site, the ITP profile describes me as a kid pretty well, and it all still applies so maybe I haven't grown up yet. :)
• INTP Profile (5) fits me pretty well, except that I don't particularly like word games.
• INTP Profile (6) from the intp.org site, also looks pretty accurate except I'm getting bored now and skimmed it too quick to really say. (grin)
