 So it is not “rational”, but neither can I say it is “irrational” simply because I don’t agree with it.  The same is true for any belief.  — Widders

You’re playing too much with the words here. Belief is not something that you choose to have arbitrarily. The Martian tuna is an example to help illustrate how we all apply our rational minds to situations, but it doesn’t compare to situations that we are immersed in from childhood. Think more along the lines of the complex stories people have about how they worked through their belief in Santa Claus. Becoming an independently thinking adult after being a totally dependent child is a process, and some people don’t get the full program, some get purposely withheld from parts it.

Beliefs are formed over time and they inform our day to day actions. If we didn’t have them, we’d have to stop and work out every step we take.
