The most convincing explanation I have heard for these problems is that inner cities massively overconcentrate lead, which is neurotoxic and causes crime/impulsivity.
That’s one explanation, I’m curious why you find it the most convincing.
Edit: if it is just lead, how come the correlation between race and IQ seems to persist across countries?

Various explanations aren’t necessarily mutually exclusive.
