Skill: Handling ideas, plans, and predictions lightly enough not to become stuck with bad ones when evidence could (should?) have pushed you into a better working model.

Roughly, this skill would involve honestly scoring as a fox on the fox vs hedgehog quiz in a self aware way... understanding some of the construct that the quiz is probing, how that construct causally connects with predictive accuracy, and how and when to engage the relevant skills. Bonus points for being able to constrain the tendencies when they are unhelpful.
