I always correct people. Is something wrong?

This is going to make me sound like a huge braggart, but I am an incredible intelligent human being. I have a wealth of knowledge on many subjects, and my intellect surpasses most of my fellow classmates (grade 11) by far.

That established, I have a problem with correcting people. Whenever I hear incorrect information being exchanged, I spontaneously correct it, often in a condescending or pretentious way. I am in fact a very nice person, and I am normally rather calm and chill, but I sound like a jerk when I constantly tell others that they are wrong.

I feel like other people grow tired of my corrections and think I am trying to show off my smarts.

This is not the case. In fact, I make a conscious effort to not speak when I here someone saying something wrong, but it feels strange somehow.

The best way I can describe it is like an itch. When someone says something wrong, eg: saying "nucular" instead of "nuclear," I feel like something has to be said about it, or else this bad feeling lingers in my brain.

I don't think I am doing this because my brain thinks it is its responsibility to prevent the spread from misinformation, so I seriously think I might have some sort of social disorder, which is strange because I am a very sociable person.

So to any psychologists out there: Is there a disorder that could explain what I am feeling? Or have I just developed a bad habit that I need to break? Is there anything I can do for it?
