Once upon a time, the United States of America had a competent president who actually grasped complex issues and could intelligently explore governmental implications. Those were the days.
Brain imaging research indicates some aspects of individual political orientation correlate significantly with the mass and activity of particular brain structures including the right amygdala and the insula. This correlation may derive in part from genetics, but is also influenced by environment and behavior.
“there’s a critical nuance here. Schreiber thinks the current research suggests not only that having a particular brain influences your political views, but also that having a particular political view influences and changes your brain. The causal arrow seems likely to run in both directions—which would make sense in light of what we know about the plasticity of the brain. Simply by living our lives, we change our brains. Our political affiliations, and the lifestyles that go along with them, probably condition many such changes.”

In a similar vein, Bob Altemeyer conducted and reported on some seminal social science research and theory on political dispositions. See http://home.cc.umanitoba.ca/~altemey/. Note the free book link on the left.
“When something is memorable, it tends to be the thing you think of first, and then it has an outsize influence on your understanding of the world. After the movie came out, a generation of people was afraid to swim in the sea—not because shark attacks were more likely but because all those movie viewers could more readily imagine them.”
Here’s a useful artificial intelligence introductory lesson from an MIT course:
Cognitive bias article of the day: How to Convince Someone When Facts Fail
A concise, timely look at how worldview-driven cognitive dissonance leads people to double down on their misbeliefs in the face of challenging evidence. It also recommends steps for having more meaningful conversations with others whose irrational positions differ from your own. 😉
Studies find that people with higher numeracy and understanding of the scientific method and its tools are more likely to challenge or twist the results of scientific studies that challenge their ideologies. For example, it’s the more scientifically competent persons on the political right (those who are most identified with a free-market ideology) who mount the most vehement assaults against claims of human contributions to global warming.
This article delves into the extent of cognitive biases against facts (rigorously validated knowledge claims) and the apparent variables affecting when those biases are triggered. It also raises possible ways to mitigate biases.
