Disingenuous discourse

‘Disingenuous discourse’ is discourse that includes action that is apparently not candid or sincere, typically by an actor (agent) pretending to knows less about something than he really does. It may be mistakenly confused with sincere humility or true ignorance (even momentary misremembering). It's documented to have been used in politics and plausibly has the most adverse effect in there along with in childrearing.
