You: We're building a bridge! It's going to be great! We've been thinking about it a bunch, and we're even starting work on it. We've got lots of great people. Let me tell you about why it's going to be great and very aesthetic. Me: Nice! Can you tell me a bit about the loads you're planning for the bridge to carry, and how they'll be supported? You: We'll work it out. We'll have great people. Great people are strong and make bridges that are strong and can carry mighty weights. Me: I'm asking about the bridge itself, not the people. How much weight will the bridge carry, and what materials will you use, and how will the loads be distributed to the pylons, and where will the pylons be embedded? If you don't think about these things and try to build a bridge anyway, it will just collapse. You: I don't get what you mean, you're being vague. Can you show a specific way that our bridge will collapse? Me: I can give an example sce...

How can we make many humans who are very good at solving difficult problems?

(Unresearched uncareful speculation.) TL;DR: Maybe eating food that's made of a bunch of different ingredients is bad because it prevents your gutbrain and headbrain from learning which foods correspond to which nutrients. Without knowing that, the brains can't accurately say when to eat what. My supporting data: It stands to reason. When I haven't eaten enough protein, I feel something's off and I'm compelled to eat more food; but I don't automatically specifically eat protein. Sometimes when I've exercised a lot, and have been drinking water, I still feel off. Then electrolytes tastes actively good, and I feel better after drinking them (and they stop tasting so good, or even taste a little bad). I had to learn this, I didn't automatically know it. One time I got sick and vomited after having eaten sweet potato fries with dijon mustard. A decade later, I still maybe wouldn't want to eat sweet potato fries, and would probably avoid the combo....
