“The Righteous Mind” by Jonathan Haidt explains that people make decisions based on emotion, not logic. Once the emotional decision is made, arguments concocted by the “rational” mind are used to justify it. The arguments don’t have to withstand logical scrutiny; they just have to seem to support the decision from the viewpoint of the “decider.”
Think about political decisions made recently by Colorado legislators. Think about whether the justifications for them make sense to you. If they don’t, remember the emotional mind.
