How politics makes us stupid – Vox

Interesting research on how we make decisions based on our pre-conceptions and our group identity/ideology:

[Yale Law professor Dan] Kahan doesn’t find it strange that we react to threatening information by mobilizing our intellectual artillery to destroy it. He thinks it’s strange that we would expect rational people to do anything else. “Nothing any ordinary member of the public personally believes about the existence, causes, or likely consequences of global warming will affect the risk that climate changes poses to her, or to anyone or anything she cares about,” Kahan writes. “However, if she forms the wrong position on climate change relative to the one that people with whom she has a close affinity — and on whose high regard and support she depends on in myriad ways in her daily life — she could suffer extremely unpleasant consequences, from shunning to the loss of employment.”

Kahan’s research tells us we can’t trust our own reason. How do we reason our way out of that?

Kahan calls this theory Identity-Protective Cognition: “As a way of avoiding dissonance and estrangement from valued groups, individuals subconsciously resist factual information that threatens their defining values.” Elsewhere, he puts it even more pithily: “What we believe about the facts,” he writes, “tells us who we are.” And the most important psychological imperative most of us have in a given day is protecting our idea of who we are, and our relationships with the people we trust and love.
