Altruism and selflessness that benefit the group are developed in individual organisms as a mechanism to increase group success.

Anti-science rhetoric is part of their anti-critical thinking stance, leaders want followers to be nice and obedient and that's just their way of making sure everyone in the flock stays nice and ignorant to the fact they're being fleeced.
