If something works you can reasonably call it true.
If it does not work, then you can know it is not true.
Should belief in what is True, that which works, lead to better lives?
Yes, it should.
Leading a life based on Truth is leading a life in accordance with the way the universe actually is, the way it actually works, and that should lead to better outcomes.
Examples of beliefs that do not conform to the real world.
I’m talking about such ideas as Astrology, magic, faith healing, and prayer (as a means for getting what you want).
I personally would also include ideas like vaccine denial, climate denial, gun rights (as a way of improving our society), and racial superiority.
Many conspiracy theories, although not necessarily all of them.
