Motivated Reasoning aka soldier mindset:
This phenomenon in which our unconscious motivations (our desires and fears) shape the way we interpret information. So some information and ideas feel like our allies and we want them to win. We want to defend them. And other information and ideas are the enemy. We want to shoot them down.
Scout mindset shows curious, open to ideas, grounded. Willing to change one’s mind based on new information. We need to proud of having changed our mind when new data shows us to have been wrong.
