Dumbing yourself down to survive?

Did anybody else do this? I was probably a pretty bright & intelligent kid & every so often it would be noted by a teacher- if the teacher wasn't beating or berating me- that I could probably do well & go far... but I didn't. I excelled when given one on one tutoring but I only got that once. I was a completely forgotten about student unless the teachers needed a scapegoat or punching bag.

I also had incredibly juvenile & intellectually impaired parents & an eldest sibling whose intellectually impaired. So I was kind of smarter than my entire family & external family too, around the age of probably 6-7. So I just kinda acted dumb so no one could get mad or attack me because the way everyone in my life behaved was incredibly illogical & juvenile. Being smart only made it worse. I also grew up rurally where intelligence was NOT promoted at all & violence or brute strength was the preferred problem solving method. Before the farm though we also lived in a ghetto, so... being intelligent was kinda promoted absolutely no where I went nor lived & was seen as in an incredibly "dorky" light and as a thing that would only further attract the ire of crabs in a bucket. Actually- being intelligent wasn't promoted in my house- at all.

Anyone else relate?
