explains a lot of the behavior on this site. Just kidding. I think.
The article states rise in crime rate in the 1970s to 1980s however quote below from Wikapedia shows Tetraethyl Lead was used as an additive since 1920s. Doesn't track, but nice try.
Tetraethyllead (common name tetraethyl lead), abbreviated TEL, is an organolead compound with the formula (CH3CH2)4Pb. It was admixed with gasoline (petrol) beginning in the 1920s as an inexpensive octane booster which allowed engine compression to be raised substantially, which in turn increased vehicle performance and fuel economy.[1][2] TEL was phased out starting in the US in the mid-1970s because of its neurotoxicity and its deleterious effect on catalytic converters.
