There seem to be flaws in this theory.

1- Hunter-gatherer lifestyles lasted for millions of years, and in some areas still do. This suggests that to some extent humans learned to restrain themselves from over-hunting.2- Agriculture didn't start up at similar times over the world, but started up in specific places and spread.3- Tribes tended to have specific (if vaguely marked) territories- similarly, farmers tended to have specific (if vaguely marked) territories- there was more freedom to move around, but it was still limited.

Seems like a good point.

Hmmm. Population size is far more important than mobility as a factor generating genetic diversity and you need very small populations to reduce genetic diversity on disease related diversity (relative to hunter gatherers). Disease increases with population size, but not for exposure or genetic diversity reasons but because the host population increases and population size and genetic variation of pathogens increases with population size of the host population.

Two explanations for why the change to farming would be:

- During the initial phase, farming would not be initially incompatible with hunting and gathering but could increase food surpluses while barely increasing the amount of work required. Gradual intensification and expansion takes place until farming societies are ubiquitous.-Greater food production for ritual purposes, which gradually move to subsistence purposes (afaik the temple preceeded the city in the archaeological record).

As to the general theory I'd be interested in seeing an anthropologist fact check and confirmation any assertions about differences between HGs and agriculturalists.

Foraging is a fairly safe occupation, genetically and tactically - you are constantly on the move, you're getting more exercise, you are randomly running into other foraging groups to exchange DNA and ideas with, and, if you're threatened by a superior invading force, you have more ability to survive in smaller groups, split up, live off the land and move on.

In other words, you are in an environment where meeting others is generally not super-dangerous, and in fact can lead to great boons. Yes, you can catch diseases, but your tribe is also probably exposed to diseases on a regular basis, building up your immune system

Farmers, on the other hand, are stuck - they are forced to live in a single location. This means:* Less safe in the face of invaders - you can't easily flee and live off the land. So every interaction with strangers can be very, very dangerous. Thus, the fear of the other.

This means: Less genetic variation, less disease resistance (reinforcing the danger of foreign interactions), fewer opportunities for trade.

When a foreign tribe shows up on the border, some small number of people need to go and deal with them. Those people end up with signficant prestige and significant power in the farm community. They represent some combination of martial leadership and political leadership.

Does this conservative? It does to me.

Now, the question - why would anyone choose this???

The answer: Because they hunted and foraged the environment to depletion - literally, they ate all the random potatoes and deer, and they had no choice - either start planting, or die. Assuming they were on some sort of large geographic cycle/circle - Probably, they noticed that the places they had visited before had large concentrations of the plants that they had gathered and foraged at camp before (all the seeds and cuttings). It wasn't a high conceptual leap to realize that they could deliberately plant these vegetables, and potentially raise livestock for slaughter, and cycle between these "specific locations". And then it's not a big leap to say "why are we walking from location A to B to C, when B is clearly outgrowing the other two

My theory, anyways

For some reason, I've noticed the studies purporting to show correlations between psychological traits and political belief almost always have pathetically-small sample sizes. For example, the study that showed that gun-control proponents etc. were more fearful had a sample size of 46.

Maybe we should wait for real evidence.

I can see how fear keeps farmers from violating social norms - fear of death is a strong incentive. But how did we get from foragers to farmers? Was fear part of the forager lifestyle as well? If not, did it develop in relation to farming? If fear was part of the forager lifestyle to keep social norms, how did those social norms change so that farmers could come around?

I think more detail is needed on the transition from forager to farmer.

Good post and important point.

you say: "Social scientists also don’t like to think about death, and thinking about explanations involving fear of death makes social scientists think too much about death."

I suspect it is also in large part that social scientists know that people do not like to think / read about death and expect that others won't like their work if they do research on it. Death is low status, always has been.

How is this theory influenced by overconfidence bias and the signaling rewards of appearing confident and fearless?

In regards to the Science paper, I wonder what might be found if such a test were performed with different stimuli. For example, how would people of different political persuasions react to a short video of someone losing their health insurance? You've pointed out in the past that fear of death can go a long way in explaining our current health care system, and the emphasis placed upon health insurance does look at least quasi-religious. We seem to be moving through different sets of enforced cultural norms and religions based upon fear of death on our way back to forager values.

I understand that more conservative individuals tend to self report greater happiness though. Where is our evidence that they are more stressed or sad or suicidal on a day to day basis, rather than merely having a transient heightened threat response to transient threats? Stress disorders might be a good thing to look at? My understanding is that on Big 5 factor analysis, there isn't a difference in the Neuroticism or Agreeableness trait between the two groups.

Perhaps you don't need to be unhappy, stressed or neurotic to be living in fear though (and can be happier living in fear than if you weren't). Though I find this counter intuitive.

That is to say, the behaviors were always there, just not represented until the power structure shifted.

Times of fear may also cause society to rely on the wisdom of the elders, and therefore their world view.

Farming required huge behavior changes, mostly unnatural to foragers.

Maybe this puts the cart before the horse -- if farming required huge, unnatural behavioral changes to get started, it seems to me that farming would be very unlikely to start, yet it seems to happen immediately after the ice age climate became suitable.

Maybe the other way -- wealth produced by farming allowed the luxury of unnatural behavior changes.

You said in your previous post

Why exactly would folks have evolved to, when rich, more prefer abortion, divorce, homosexuality, and leisure, and less kids religion, patriotism, and authority?

This seems strangely backward to me -- rich societies allow these things, but the wealthy members of the richest society on earth seem to believe the opposite (maybe just because the wealthy tend to be older). Young foragers, vs older farmers?

Maybe foraging vs farming shifted the balance of power in society from young hunters chasing down meat and young gatherers with good eyes to older farmers who'd had more experience growing crops?

Here is a good, strange story on the same idea, asking whether the Biblical Eden was just the pre-agricultural world. So maybe we're heading back toward Paradise.

Would then fans of horror movies, which often show shocking/startling imagery, be then liberal or conservative?

Also, I find this link counter intutitive:

"Individuals with measurably lower physical sensitivities to sudden noises and threatening visual images were more likely to support [...] gun control"

Why would people with lower sensitivities to sudden noises (like gunshots?) and threatening visual images (like guns?) be more likely to support gun control? Wouldn't those fearful of death and loud noises be more likely to support bans on guns, since they're almost always associated with those things? There was a time when gun control was associated with very different political factions.
