I tend to agree with your assessment that the balls in their Court and they can do what they want
Sometimes it's fine to sit back and let people make their own decisions and even mistakes, as long as they don't adversely impact you.
nobody has perfect information. that is the human condition. We dont know the future: how our lives will develop, how our marriages will end, what our kids will be like, and when and how we will die.
for example assuming they are granted to own the land they live on, we could not just let them sell the right to logging and let others destroy their land. so we need to be careful which the choices we allow them to make. eg, if they want to move into the city, fine, but then we need to make sure they can reverse that decision and go back, or at least continue some of their lifestyle. iaw: the problem is irreversible decisions that are difficult to understand.
but also problems caused by learning about alcohol, depending on government support, education that doesn't respect their culture and knowledge, etc.
so my approach would be to teach them knowledge they can use to improve their lives, introduce them to the idea that others live in other ways, but also that it takes an effort to change their lifestyle. like they will have to learn new trades in order to get jobs and earn an income if they want to do that.
“I’d far rather be happy than right any day.”
In the past, this particular aspect co-occurred with colonial genocide and economic exploitation. But that is not an excuse to stipulate that there isn’t an objective benefit to the progress of understanding and culture.
Trade is disastrous when suddenly all local production has to compete with hyper efficient imports, but there's no export to really pay for imports. The damage to local production happens despite the imbalance. Repeatedly give a man a fish and sooner or later he will forget everything he ever knew about fishing.
And what level of experience we are looking at! Remember the 10000h rule? Imagine a group developing exactly one skill set since childhood. Trained by a chain of ancestors following the same path that would make the Bene Gesserit blush.
This would all collapse under contact. A few years of handouts and/or one-time trades and nothing of those abilities would be left. And those years would be far too short to find a place in the new (to them) market above that of beggars and thieves. They would have trouble even working as prostitutes not knowing the cultural codes around that.
I agree with you on many points, but the word "preferable" is doing a lot of heavy lifting here. It doesn't describe who it is preferable to, or how objective outcomes inform people's preferences, or whether this preference only exists when it is non-uniformly distributed across the world.
I believe that more precise empirical knowledge of the world is preferable, but I don't think it generalises - or naturalises - to human cognition. Or that it is causally related to reduction of colonial genocide and economic exploitation.
Anecdotally, I know a number of people who prefer their "objectively better" life courtesy of vigorous anti-intellectualism, conspiracy, religious fundamentalism, internalised naturalisation of race/gender/faith/etc. And other cognitive distortions - as I would call them.
Again though, I agree with you because I believe (among other things) that less human suffering is preferable, increased longevity is preferable, our species surviving longer is preferable, and other species surviving with us is also preferable. And I believe more precise empirical knowledge is the best way to achieve those things.
But many, many people disagree, and many just believe differently. As far as we know, that disagreement is not due to a kind of naturalised deficiency of cognition.
