I like to say "the gut is the first brain". There's a reason we perform "gut checks" and "go with our gut" -- it's the first instinct, while the second is the rational systems overlaid on the initial reaction that serve to verify or correct them. Compare with Kahnemann's System 1 and System 2.

We do not have "gut checks" and "going with our guts" because of some ancient wisdom about physiology that only left remnant traces as idioms in English.

Also, Kahnemann talked about conscious and unconscious thought, not about "gut thought" and "brain thought." You can teach yourself to behave in certain ways, to just react. That doesn't mean you have a smarter stomach than the next person!

It feels like you're just being contrarian without actually putting in the effort to understand. To imply that somatic experience has no influence whatsoever on worldview and by extension on language seems like a very radical position to take given all we know and continue to learn about psychology and neuroscience. I don't think layering on "smarts" onto this discussion is warranted either.

Kahnemann's framework maps neatly onto this idea if you consider the seat of unconscious thought not to be localized in the brain (i.e. that all neurons think to some extent), and the seat of conscious thought to be in the prefrontal cortex and its tight interconnections with other brain regions via the default mode network.

I agree. Rationality is invariably a rationalization of gut and emotion and such. A wrapper of symbols so we can think and talk about it. And justify our conclusions.

The enteric nervous system certainly evolved first!

Article is about cells in the gut that we barely knew anything about, due to stomach acid and bile making it hard to identify their genetic material. Some researchers are making progress in this area and it's amazing.

There was a breakthrough in studying the gut biome about a decade ago. Since then we have started to learn so much.

Gut health is absolutely linked to mental health. Besides actual scientific research that backs this up, I didn’t really get my mental health under control until I took care of my gut issues like IBS and stuff. Also avoiding certain foods, not gluten obviously that’s a crock of shit, but things that obviously don’t work with my body like cream sauces or whatever
