“Lucifer is not the name of the devil, and does not refer to anything innately evil. Lucifer is just the Latin name for a reflected image caused by a toxic lead-contaminated environment.”

Rick Nevin is an economist who is best known for his peer-reviewed research showing the relationship between preschool lead exposure trends and subsequent international crime trends, and U.S. trends in unwed teen pregnancy, Scholastic Achievement Test scores, and intellectual disability (ID). He has also written a short book, called Lucifer Curves, that updates and augments his research showing that lead exposure trends explain ongoing international crime trends, shifts in the peak age of offending dating back to the dawn of the industrial revolution, and converging U.S. racial trends in ID prevalence, unwed teen pregnancy, and arrest and incarceration rates.
