So, if we want to influence human behaviour in the modern world (first child at 20 or 30? Is aggression linked to desire / see to hunt?) can we take the lessons here and apply them to urban design?
Even if it was the right choice, these sorts of things have a dizzying array of unintuitive results and even the academics involved are still working out a lot of the implications. In particular, we don't have a good understanding of how applicable these results (and the wider predictions of HBE) are to non-foraging human societies.
I think we do know of plenty of anti-patterns (ie concrete monstrosities, lack of local walkable amenities) so urban planning is still a Good Thing. If done right.
The only question is what behavior we’re trying to achieve and how we’re manipulating the environment to achieve it.
