Tribal affiliation is the biggest threat to intellectual humility. It is insidious–we join tribes emotionally and organically–there is not official signup form, so we don’t even know that we joined. Once we join, the confirmation bias takes over, making us hubristic and even willing to fight for things we didn’t choose to believe.

The solution is to disengage, to step out of one’s tribe. That is extremely difficult once we get used to the comfy confines, the smiles and encouragement of our comrades, the non-stop warmth of that feeling that of belonging, the feeling that one is always at home. Once we are comfy, we turn off any thoughts that maybe we don’t belong. We are completely credulous regarding tribal dogma. Stockholm Syndrome takes over. We become our own prisoners, setting up electrified fences to cordon off any improper or impure thoughts. The only hope for most people is that external tragedy resulting from the dogma comes crashing in, resulting in depression, nihilism and scales falling from our eyes. This might offer us a more-or-less blank slate on which to rebuild, a chance to build one’s own belief system based on intellectual humility: curiosity, skepticism and evidence. More likely, it merely sends one on a shopping trip to join the next most attractive tribe.
