Martial arts can be a good training to ensure your personal security, if you assume the worst about your tools and environment. If you expect to find yourself unarmed in a dark alley, or fighting hand to hand in a war, it makes sense. But most people do a lot better at ensuring their personal security by coordinating to live in peaceful societies and neighborhoods; they pay someone else to learn martial arts. Similarly, while "survivalists" plan and train to stay warm, dry, and fed given worst case assumptions about the world around them, most people achieve these goals by participating in a modern economy.
The martial arts metaphor for rationality training seems popular at this website, and most discussions here about how to believe the truth seem to assume an environmental worst case: how to figure out everything for yourself given fixed info and assuming the worst about other folks. In this context, a good rationality test is a publicly-visible personal test, applied to your personal beliefs when you are isolated from others' assistance and info.
I'm much more interested in how we can can join together to believe truth, and it actually seems easier to design institutions which achieve this end than to design institutions to test individual isolated general tendencies to discern truth. For example, with subsidized prediction markets, we can each specialize on the topics where we contribute best, relying on market consensus on all other topics. We don't each need to train to identify and fix each possible kind of bias; each bias can instead have specialists who look for where that bias appears and then correct it.
Perhaps martial-art-style rationality makes sense for isolated survivalist Einsteins forced by humanity's vast stunning cluelessness to single-handedly block the coming robot rampage. But for those of us who respect the opinions of enough others to want to work with them to find truth, it makes more sense to design and field institutions which give each person better incentives to update a common consensus.
Extraordinarily so, yes -- it does astonish me that no one hit it before. Nonetheless, the empirical fact remains, so...
I suppose the sense of "mystery" people attached to life played into it somewhat.
People were breeding animals, people were selecting them, and...socially there was already some idea of genetic fitness. Men admired men who could father many children.The idea of heredity was there.
Honestly, the more I think of it, the more I share your confusion. It is deeply odd that we were blinded for so long. Perhaps we should work to figure out how this happened, and whether we can avoid it in the future.
I don't think luck can factor in quite as much as you imagine though. We're not attempting to award credit, so much as we are attempting to identify circumstances which tend to produce people who tend to produce important insights. Darwin's insight was incredibly important, and had gone unseen for centuries. To me, that qualifies him.
Even if you put it at a remove, even if you say, well, Darwin was uniquely inspired by his voyage, another biologist could have done the same, then the voyage becomes important. Why didn't another biologist wind up on a voyage like that? What can we do to ensure that inspiring experiences like that are available to future intellectuals? In this way, Darwin's life remains an important data point, even if -- especially if -- we deny that there was anything innately superior about the man.
Agreed, completely -- they pulled the low-hanging fruit from the search space.
