I would think even placebos provide value... Like a rough economic cycle, picking up a new skill, or learning to program, sometimes I have to slog through something difficult that does not seem to be getting me anywhere before the light bulb goes on and I realize "oh, THAT'S why this whatever is done that way." What's that other adage? Fake it till you make it?
