Hmm, where do I start?
OK, I've wasted half a life time listening to INTPs drone on about a topic they're interested in. The thing is, it's quite often stuff that I'm also interested in, but by the time they've finished they're extended monologue I feel I've almost lost the will to live.
I've never met such a bunch of under achievers! I can't fault your knowledge or your logical reasoning, but why not try doing something useful with it? Knowledge is not an end in itself it's a tool to be used to solve real world problems don't you get it?
No one really cares how much you know or don't know. You may be lucky and have a superb manager such as an INTJ who will recognise your talents and tap into them to get a good solution, but more often than not you'll be overlooked for promotions because you appear to be lazy, indecisive, overly critical and argumentative, and frankly they'd rather be around someone they can have an enjoyable conversation with.
As for managing people:I almost split my sides laughing when I saw that someone had started a thread on INTP management. You can hardly manage yourselves never mind anyone else. You may have an understanding of astro-physics and be able to prove that x billion years into the future the universe will cease expanding and will reach a point of equilibrium, but you have a very tenuous grasp of what you'll be doing tomorrow evening (or possibly this evening).
In summary, INTP: a waste of a life.
