i also easily get influenced by what i read for example, reading about gender wars i took a fresh look at my friends, spotted a guy who was slightly girly and went ahead and screwed him over his gender on Fb staus messages, probably spoiling my image infront of a whole bunch of school friends. which i do regret now :O
as a fellow ENTJ, i know that thinking before speaking is a difficulty for us. when i find something new that i'm really into, i have to pause and get a hold of it rationally so that i don't become consumed by it and say things that i'm going to regret or, even worse, have to take back later
.
how old are you, by the way? it could just be that you haven't really learned or had time to hone this skill. i'm 23 and only recently i've learned to closely scrutinize everything i say or write to minimize the damage i can do to other people.
besides Is it compulsory to talk about movies and sports all the time? i dont particularly find value in these. Perhaps i should try to like more of what society in general likes?!
i've found that it's all in "how" you talk about these things. an INTP friend of mine loves football. personally, i've never seen the point. after going to his place for a few games i've learned to appreciate the players as athletes and have come to recognize the amount of planning it takes to make a good play (see the last quarter of the Patriots/Colts game this past season, as an example) and enjoy watching it now. also, it's a great social activity and more can be talked about that just sports.
as for movies, i'm a geek and love analyzing them. the simplest thing as the way a scene is shot can have so much meaning that it can hold the entire point of the movie.
in short, after at length, try having the conversations you want to have rather than the kind everyone else is trying to have. you might find that other people are thinking the same thing and just not speaking up (a major problems for XXNX in general, i would imagine), or you might challenge them to think differently. also, most of my friends are NT, or at least an N of some sort. trying scrounging up a few of them!
as for your experimenting, i went through a similar phase where i had a job that left me entirely too much time to think. i would have imaginary conversations with my friends and then move our real life conversations in that direction to see how close i was to my imagined opinion that they would have. what resulted were really boring conversations because i knew what they were going to say before they say it, and my relationships suffered because of it. my advice to you here is to just stop doing that. it is going to hurt you more than it will help you, at least with your friends, anyway (enemies are different story
). the point of friends is that they are people you can grow and share with
. they are not variables in an experiment and shouldn't be treated that way, whether intentional or not.
