Fake AF.

OOP is too good at writing and is too self aware to have an IQ of 89. You can spend thousands of hours teaching an 89 to read and write and they'll struggle to make it past the 6th grade level. "I enjoy going to the store because it has what I need. Sometimes I see people I know. It makes me happy" is the level of writing expected at that IQ level. Very low levels of reading comprehension and written complexity.

There's a reason the US military won't take anyone below 87. It's just not possible or cost effective to teach someone that low in IQ how to do ANYTHING. They can't even be cooks or truck drivers since simple instructions don't stick in their brain. Something that takes 1 hour for a 100 IQ to learn takes an 87 IQ 1000 hours to only fail 50% of the time at.

As much as we all joke about people on 4chan being idiots, if oop was an 89 he would have been stopped by the captcha.
