I consider myself quite a slow reader, but not because I have trouble with words, but because how often I daydream while reading.
Quite often while reading, I 'll suddenly stop and stare into a space, lost in thought, brought on by something I've just read. I don't even realise I'm doing it, then I suddenly think "... oh yeah, I was reading".
I don't mind too much, but it is just slightly annoying because I could get through books a lot faster if I didn't. My ISTP cousin can get through books much faster; when he reads, he starts and doesn't stop until he has decided to stop reading.
So is it an INTP thing, an NT thing, or is it just me?
