I love HNs little obsessions. Lead causing aggression is one of them. I feel like I've seen links about it for years, and I'm not sure I've clicked a single one

  It's not something that originated here. These hypotheses are based on correlation. That does not imply causation though. Disclaimer: my educated guess is that there is probably a real connection between lead and functioning of nervous system. Element particles/molecules probably have very high ability to diffuse through complex systems due to their small particle sizes.
