I am claiming that this is at least sometimes true, yes. Not always, but sometimes.

You're the one claiming that partial revelation is always, without exception, superior to total ignorance. That seems unlikely. Propoganda is often partial revelation, are you saying it is always better to receive only propoganda than to receive no information at all?

Like if I tell you that your boyfriend has been having secret meetings with some woman you don't know, with full knowledge that the secret meetings are because she's a photographer and he's planning to propose, have I improved things by disclosing the information to you in that manner? Were my actions a "net positive"?
