No. Or, well, not exclusively. You certainly aren't particularly smart, but you're not an idiot. You understand things better than most idiots I know. No, I mean that your motivations are simple.

On the one hand, that's not something I can truly empathize with, and it's a bit boring to figure out... But, on the other hand, it is somewhat nice to have someone like that. If my expectations of you are simple, it's harder for you to betray them... I can sympathize with that much of your outlook.
