Exactly. It’s pretty clear at this point that humans cannot be trusted to make good decisions. What we want is the easiest option. Almost always. We then want someone to tell us it’s not our fault for being weak willed.
Psychology is always being used to manipulate people because you can’t expect them to make good choices on their own.
Then again there are those who cannot always make good decisions even if they want to, since you speak of psychology.
In other areas of life we'd protect them rather than punish.
