Sadly, because of our tribal brains, science carries a hefty cost. Treasured ideas that are loved by the community may be left behind, unable to compete with conflicting observations. Admired heroes may be found to have been mistaken. Years of hard work can amount to nothing thanks to a single observation, making a lifetime of effort seem like a waste of time. For our tribal brain, the philosopher’s toolbox is full of double-edged knives, capable of cutting away our hopes with the myths.
