...and I mean normal as in consistent with other INTPs, since normality is a relatively "relative" word to us
Maybe this is just a rational thing, but I'm not sure if this applies to other INTPs specifically, but I, myself, have this admittedly bad quality of always wanting to be right in any argument, almost to a pathological sense. A recent example was flaming on the internet, but this time letting the argument run for pages after pages, even though logically, this would do nothing in the long run to help me since it goes on endlessly - I have been forum clean(besides this one) for almost a month now and feel much better.
However, this doesn't end here, when I hear something spoken absolutely devoid of logic between friends or family, it really, and I mean REALLY bothers me enough that I more often than not, say something to them and an argument will ensue. Arguing with an ISFJ is the worst since at their worst, they have no objective criteria and cannot fight tete-et-tete in terms of abstract concepts, and end up just yelling.
But a lot of the things that make me angry are little things like a friend's gf inferring creationists views at a dinner table and completely wanting to lay waste to them, or someone trying to size me by being pedantic about my work on purpose. Lately, I've been trying to bottle up these needs, but I think that's really unhealthy.
Picking and choosing battles is something I am trying to relay in the coming new year, but it annoys/irritates the HELL out of me if someone is going to go around thinking they are right and insulting my intelligence.
