In one century, we've added 28 years to our average life span - a change so rapid that our brains couldn't possibly have evolved to accommodate it.
Bracketing has turned all my experiences, remembered and present, into a gallery of miracles where I wander around dazzled by the beauty of events I cannot explain.
Standards of beauty are arbitrary. Body shame exists only to the extent that our physiques don't match our own beliefs about how we should look.
My point is that perceptual bias can affect nut jobs and scientists alike. If we hold too rigidly to what we think we know, we ignore or avoid evidence of anything that might change our mind.
