My ‘belief’ System

I was thinking of the concept of ‘belief’ and the different things people believe, when a interesting thought came to me: Instead of just evaluating your beliefs based on what is true, (which is important though), evaluate them based on how they effect you.

So, here is the basic system I came up with:

1. True and Constructive Belief: Good
2. True and Destructive Belief: Action Needed
3. False and Constructive Belief: Caution
4. False and Destructive Belief: Discard
