A chat on 4chan

Some people out there lack internal monologues and can't picture things as simple as an apple in their head. They are incapable of real thought. These are NPCs.

the internal monologue thing is overrated. Its basically horoscope shit for midwit retards on 4chan. 

Basically everyone has an internal monologue, so they show you a study saying 17% of people don't or something and you guys go HEY I HAVE A MONOLOGUE THAT MEANS I'M SPECIAL AND SMART!

No you're not. They're playing you for a fool like people obsessed with horoscopes.

On average a study found that only 26% of participants had an IM. Most studies I see on the topic say anywhere from 25 - 50% which would honestly explain alot. Just because you have something doesn't mean everyone else does. Have some empathy retard.
