Those things all turn out to be real benefits from the explore perspective of what you want is to learn as much as you can about the world and explore as many possibilities as you can. And what my lab and a bunch of other labs recently have been doing is showing that you can show even formally that children are making those kind of high temperature explore decisions compared to apps. So there's evolutionary backstory that you posit in this paper. I think that's really interesting to ask into that question, why is it precisely that the human childhood is so much longer? The childhood of our fellow primates. And you say here, it is plausible that increased environmental variability was associated in particular. I'm thinking of the paper that David Wohlpert and David Krakauer just recently wrote in response to condemnation of noise. And Daniel Kahneman and his co-authors, and how they're saying, well, when you don't know what the problem is, you need to leave it open for a while. There's this thing that's going on where it seems like we have taken the shape of our ancestral, unpredictable environment that in some way our plasticity is the consequence of our having been subject to climate shifts and migratory forced movement over the surface of the planet. Speak to that, please. It's interesting, Michael. You know, I haven't really thought about that before, but I think it is interesting that someone like Daniel Kahneman is anti-noise, right, because the perspective of grown-up cognitive psychologists in the sense of people who mostly study the cognitive psychology of grown-ups. And in fact, the whole field that Kahneman was one of the founders of judgment and decision making, that's about judgment and decision making. It's not about learning and exploring. It's about once you have the information that you have, how do you actually go out and make the right kind of decision? And that's been the focus of so much energy and beautiful work in grown-up adult cognitive psychology. And I think it's interesting, as you say, that of course from that perspective, noise is the enemy. And Danny's new book is about noise being the enemy. And this is kind of a classic, explore, exploit trade-off if you're thinking about it not from the perspective of judgment and decision making, not from the perspective of adult cognitive psychology where the job really is go out and make good decisions quickly and effectively. But think about it from the perspective of child psychology where the job is to explore as many possibilities as you can. Then having a lot of noise and variability actually turns out to be crucial. It turns out to make a lot of sense. And it makes sense to have a system that can do both, that can start out being noisy and variable, but also is capable of narrowing in late on. Now in terms of your point about what was the evolutionary trigger for this, I think as always with evolutionary explanations, the best answer, especially for humans who evolved so distinctively so quickly, the best answer is a kind of cascade effect. So there is some evidence that there were changes in the logical context because of things like climate variability. So now we cause climate change in the past, climate change caused us. But part of what happened is that as a response to that, we also get humans being able to do things like design their own environmental niche to alter the environment in ways that other primates, for example, don't. So systematically altering the world that we're in. And we also have humans being involved in cultural transmission so that one group could find something out and pass it on to another group. And as you mentioned, one of the things that's really distinctive about humans from the time we evolved is that we're very nomadic. So primates are still pretty much in the same places in Africa that they evolved in. So as soon as we were human, we were going out and moving. And we put all that together. And what it means is not only were there the ecological changes in the environment, but we humans ourselves change our environment with each generation because we need altered the environment. And then we move around from one environment to another. So all that means that there's this kind of cascade of being sensitive to environmental variability. And then finally, because humans are such a cooperative social species, and again, there's a kind of interesting cascade here. People like Sarah Hardy have said, it's precisely because we have to take care of those helpless children for so long.
