Are you implying that there's a direct correlation to people correlated vs IQ level/lead count in blood? Or is this just a case of pirates vs global warming? [0]
It's not me implying it - the article I linked to did, and pretty conclusively too.
That graph you posted is messed up (yes I get it's a joke), but the spacing between dots randomly changes from 20 to 40 years. That graph actually demonstrates that there is no correlation, otherwise they would not have tried to mislead people.
Thanks for the link,btw. That was fascinating.
