MINNEAPOLIS—A study published Thursday in The American Journal Of Criminal Psychology has found a nearly perfect statistical correlation between children who were denied a toy they wanted when visiting a store with their parents and the later development of homicidal behavior. “We found that even after just one instance of being told ‘no’ in a toy store aisle, children may begin to exhibit their first violent impulses, which often later manifest as a compulsive need to kill others during adulthood,” said forensic psychologist Edgar Pruitt, whose study tracked the emergence of deviant, psychopathic traits that first began to appear when each future killer left a store without a new Nintendo game, G.I. Joe, or remote-control car. “John Wayne Gacy, Jeffrey Dahmer, the Green River Killer—these were all people who did not get the toys or games they wanted. So as a parent, you have to ask yourself if the $15 you save by not purchasing Legos or a Spider-Man figurine is worth the potentially dozens of innocent lives your child might one day brutally take.” The study also found that young girls who were told they had to eat their dinner before they could have dessert went on in 100 percent of cases to become mothers who drowned their own children one by one in the bathtub.
