Mass and activity of brain structures correlate with political perspectives

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.


Politicians use ‘salient availability’ bias to manipulate constituents and journalists


“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 Jaws 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.”

Living in a ‘post-fact’ world

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.

Comment I posted there:
Here is an interdisciplinary “moon-shot” suggestion that we should at least start talking about, now, before it is too late. Let’s massively collaborate to develop a very mission-specific AI system to help us figure out, using emerging genetic editing technologies (e.g., CRISPR, etc.), ideally how to tweak (most likely) species-typical genes currently constraining our capacities for prosociality, biophilia, and compassion, so that we can intentionally evolve into a sustainable species. This is something that natural selection, our past and current psycho-eugenicist, will never do (it cannot), and something that our current genetic endowment will never allow cultural processes / social engineering approaches to adequately transform us. Purposed-designed AI systems feeding off of growing databases of intra-genomic dynamics and gene-environment interactions could greatly speed our understanding of how to make these genetic adjustments to ourselves, the only hope for our survival, in a morally optimal (i.e., fewest mistakes due to unexpected gene-gene and gene-regulatory (exome) and epigenetic interactions; fewest onerous side-effects) as well as in a maximally effective and efficient way. Come together, teams of AI scientists and geneticists! We need to grab our collective pan-cultural intrapsychic fate away from the dark hands of natural selection, and AI can probably help. END
