  1. TAKE A CLOSER LOOK at the graphs @ 18:34. SURE...the red and white lines look similar BUT they arent occurring at the same time frame.....then LOOK AT THE YEARS IN RED AND WHITE, ABOVE AND BELOW the graphs. For example USA lead levels in preschoolers are measured from 1936 to 1996 start to finish......BUT...the crime rate graph in white is from 1959-2019. So 1969s crime rate overlaps 1946s pre school lead levels. And 1999's crime rate overlaps 1976's lead levels...there is over a 23 year gap. Britain and Canada have over 19 years difference between the charts, and australia 18 years. So for example in the USA...even though the blood levels of lead steadily DROPPED from 1970 to 1990...in fact the crime rate INCREASED from 1970 to 1990. Proving there isnt a correlation between the two....maybe even an inverse relationship....LOL
