I used to work in an engineering firm and the way I'd explain some of my coworkers' inanity to my wife at dinner is that the engineering mindset is to search for simple, elegant solutions to complex problems, and in cases where there is no such simple solution (let's take social or political issues as a common thread, here) that tends to lead to the engineer preferring a spherical-chickens-in-a-vacuum oversimplification over the complex and nuanced reality -- usually accompanied by protestations that "If only people would act rationally!" their ideas would work and make things better.

There's some overlap as well between engineers and the sort of mentality that one is a disembodied intelligence piloting a meat puppet, which feeds into those sorts of thought patterns. Like, dude, you may think of yourself as a purely logical being, but the fact of the matter is that like all of us you're a bodge-job mess of higher-order thinking strapped to a tribal ape with duct tape and baling wire. You can't ignore the rough edges that come with that if you want to find social or political ideas that actually work.
