I highly recommend this [1] book on the topic as we navigate a post-truth world. The Narcissist's Prayer is also worth a read [2].
It's not all narcissism though; it can be difficult to reason with deeply ingrained belief systems when there is a lack of critical thinking and challenges to the Id and ego, not to mention innate tribalism.
EDIT: Agree with the deleted comment that The Narcissist's Prayer could also be The CEO's Prayer, based on the personality type the C suite attracts [3].
