I'm tired and discussions have been lacking

So here is a list of common things that may or may not be forms of deception, practiced both on oneself and on others.
Religion: Is it useful to think your being watched? Judged? Loved? Forgiven? Tested? Assuming these things are not true. When you know your being observed it changes you psychologically(I'll find a source if anyone contests this, just don't have one on hand) It makes you more efficient, could this effect be gotten by thinking you are being observed if it was actually believed? It might also help make you more courageous, but you could argue semantics and say that this is feign-courage, but you could also argue effectiveness and say that it helps you accomplish a goal... but then you could argue it might hinder you in future goals, such as those that require objective reasoning.
Atheism: Assuming there is a God, could it be useful to ignore God? I have opinion on this I'll share if/when someone questions this. For now, maybe God doesn't want to be bothered or noticed? Maybe God just contemplates as Aristotle says, in which case we shouldn't bother God at all, even in thought, but then again, in a state of pure contemplation can anything really bother you?
Prophecy: Is it useful to put stake into possibilities like "the world coming to an end?" Assuming it isn't, but if it was coming to an end, could it be useful in thinking that it wasn't?
Conspiracy: Even if there are no secret societies in charge of the world, is there a useful purpose to think there are?
Self Help: It doesn't always work, but sometimes it does. You can argue that the self help didn't do anything that the person couldn't do on their own, but then again, THAT isn't the deception, after all, it is called SELF help. "This thread has a purpose, this thread has a purpose, this thread has a purpose" "It's going to attract lots of interest and cause a chain reaction of interesting posts, It's going to attract lots of interest and cause a chain reaction of interesting posts, It's going to attract lots of interest and cause a chain reaction of interesting posts." we'll see
Psychiatry: In the same field as self help, except there is at least SOME rather convincing circumstantial evidence that goes into psychiatry.
Leadership Training: In the same field as the two above, but leadership training is endorsed by military, super rich corporations as well as spiritual and political leaders... there must be some truth to it, but again, you don't change at all, a different part of you is brought out, and/or you learn to use your different parts in a different way... leadership itself can be seen as a deception in some of it's forms, you really are not leading you are giving the impression of leadership and so people follow you and the cards fall into place... this might be the exception and not the rule, but it still inevitably occurs, people are thirsty for leadership. Something as little as standing tall with your chest out makes people respect you more, so long as you don't over do it.
Entertainment
Propaganda
Ego/Personality: YOU know who YOU are!
Meatless hot-dogs: not deception for everyone, but SOMEONE out there is fooling themselves... then again maybe "curd tubes" didn't sell so well
Masturbation: This ISN'T deception on it's own, but it tends to work better when it is
My main concern with self deception is the anxiety it can create. For example thinking there is a God(assuming there is not) can create a lot of anxiety for someone, depending on the nature of that God and the individuals relationship with the God.
