Nuh uh, I was thinking about it last night, and you could make such a build! Make a character with Uneducated and the mental disability flaw... You could also use some custom flaws like Lack of Common Sense (the GM can force your character to do the exact wrong thing at key moments), and maybe a few different varieties of Poor Self Control. You'd need to exceed the 35 point flaw limit, which would be cool cuz you'd end up with a more powerful build, but he'd be too stupid to do anything right and would probably get killed or get the team killed. That would be sweet 

HAHA, well if you are going the custom route you should port the Stupid Trait from Burning Wheel (Traits effectively analogous to Qualities). Yes, it's actually named "Stupid". It adds +Ob1 (+1 Threshold) to all attempts at social Skills used by the character and used on the character. You aren't going to convince anyone of your wrongheaded ways but damned if they are going to be able to turn our your lightbulb on to defect you from your path.
