> You can either take a defeatist mentality, or the one OP describes. One of those, in every situation, will work better for you than the other.

I have to take sides with you. Title says "rigged in your favor". Paranoia is the opposite; as in things and or people are rigged/rigging against you. Pronoia is the belief in the opposite that people are actually wanting the best for you and even conspiring to lift you up.

As you said one works better than the other. Whether either is true in any given scenario. One feels better and works better.

Does anyone really believe thinking things are rigged against them is a productive mindset?

Not really a good or funny use of the word Stabby. Plus it was a Mrs who was stabby. You had a great opportunity to reuse a worn out joke and blew it.
