The brain's threshhold for 'certainty' is repeatability/reliability. If we can reliably repeat something, the brain takes that as certainty.
Or, if we are repeatedly told something is true, we might just believe it via brainwashing.
How does this happen? Repetition makes the brain generate a feeling of certitude.
So, repeatability is all the brain asks for to pass the threshhold, and that's why I think it's futile to search for absolute truth: because the brain is not geared to find it.

"As scientists learn more about how our brains work, certitude is coming to be seen as a vice rather than a virtue".
