Suffering is more or less caused by false beliefs & unrealistic expectations, so if we are suffering, it is time to question our beliefs and expectations IMO @patrickulrich. Faith in things that make sense = ease, faith in falsehood = poor choices > mental illness > delusions.

I think if you test the limit of your beliefs enough, you see quite quickly how they are flowed

Yeah, that's true @theophile.roos testing beliefs is one sure way to figure out which beliefs are true, and which beliefs are false. Just be sure you actually want to know what is true or false, otherwise you will likely stay attach to falsehood to fit in or just out of habit.
