Ratchets Within Ratchets



For those interested in political philosophy, or Trump's travel ban, I recommend this discussion on Scott Aaronson's blog, which features a commenter calling himself Boldmug (see also Bannon and Moldbug in the news recently ;-)

Both Scott and Boldmug seem to agree that scientific/technological progress is a positive ratchet caught within a negative ratchet of societal and political decay.

Scott: An interesting term, “ratchet of progress.” Nature is full of ratchets. But ratchets of progress — extropic ratchets — are the exceptional case. Most ratchets are entropic ratchets, ratchets of decay.

You happen to live inside the ratchet of progress that is science and engineering. That ratchet produces beautiful wonders like seedless watermelons. It’s true that Talleyrand said, “no one who remembers the sweetness of life before the Revolution can even imagine it,” but even Louis XIV had to spit the seeds out of his watermelons.

This ratchet is 400 to 2400 years old, depending on how you count. The powers and ideologies that be are very good at taking credit for science and engineering, though it is much older than any of them. It is a powerful ratchet — not even the Soviet system could kill or corrupt science entirely, although it’s always the least political fields, like math and physics, that do the best.

But most ratchets are entropic ratchets of decay. The powers that be don’t teach you to see the ratchets of decay. You have to look for them with your own eyes.

The scientists and engineers who created the Antikythera mechanism lived inside a ratchet of progress. But that ratchet of progress lived inside a ratchet of decay, which is why we didn’t have an industrial revolution in 100BC. Instead we had war, tyranny, stagnation and (a few hundred years later) collapse.

Lucio Russo (https://en.wikipedia.org/wiki/Lucio_Russo) wrote an interesting, if perhaps a little overstated, book, on the Hellenistic (300-150BC, not to be confused with the Hellenic era proper) golden age of science. We really have no way of knowing how close to a scientific revolution the Alexandrians came. But it was political failure, not scientific failure, that destroyed their world. The ratchet of progress was inside a ratchet of decay. ...
It doesn't appear that Scott responded to this dig by Boldmug:

... Coincidentally, the latter is the side [THE LEFT] whose Jedi mind tricks are so strong, they almost persuaded someone with a 160 IQ to castrate himself.

And the Enlightenment? You mean the Enlightenment that guillotined Lavoisier? “The Republic has no need of savants.” Add 1789 and even 1641 to that list. Why would a savant pick Praisegod Barebones over Prince Rupert?

You might notice that in our dear modern world, whose quantum cryptography and seedless watermelons are so excellent, “the Republic has no need of savants” is out there still. Know anyone working on human genetics? ...
Don't believe in societal decay? Read this recent tour-de-force paper by DeCode researchers in Iceland, who have established beyond doubt the (long-term) dysgenic nature of modern society:
Selection against variants in the genome associated with educational attainment
Proceedings of the National Academy of Sciences of the United States of America (PNAS)

Epidemiological and genetic association studies show that genetics play an important role in the attainment of education. Here, we investigate the effect of this genetic component on the reproductive history of 109,120 Icelanders and the consequent impact on the gene pool over time. We show that an educational attainment polygenic score, POLYEDU, constructed from results of a recent study is associated with delayed reproduction (P < 10^(−100)) and fewer children overall. The effect is stronger for women and remains highly significant after adjusting for educational attainment. Based on 129,808 Icelanders born between 1910 and 1990, we find that the average POLYEDU has been declining at a rate of ∼0.010 standard units per decade, which is substantial on an evolutionary timescale. Most importantly, because POLYEDU only captures a fraction of the overall underlying genetic component the latter could be declining at a rate that is two to three times faster.
Note: these "educational attainment" variants are mostly variants which influence cognitive ability.

From the Discussion section of the paper:
... The main message here is that the human race is genetically far from being stagnant with respect to one of its most important traits. It is remarkable to report changes in POLYEDU that are measurable across the several decades covered by this study. In evolutionary time, this is a blink of an eye. However, if this trend persists over many centuries, the impact could be profound.
