Democracy's design...
The scarce use of technology to encourage and access crowd wisdom. (Rather than the cleverness invested in things like gerrymandering and misleading advertising techniques.)
This is a similar phenomenon to the pathological cleverness used in so much social network advertising... you know, bait and switch, the devil's-in-the-details approach to supposed fellow decision makers.
I'm an anthropologist not a software guy. But the solutions are fairly obvious which I try to address elsewhere. Fortunately the reception is getting better in some places.
