Kids Who Don’t Do This Might Grow up to Be Psychopaths, Researchers Find
Laughter is contagious. Actually, even moods are “catchable.” Since social contagion is an established human reaction, this new report is as surprising as it is creepy. It finds that children with the potential to develop psychopathy tend not to laugh along with others. They are naturally inoculated from social laughter. University College London (UCL) researchers in the UK came to this conclusion. Their findings were published in the journal Current Biology. Psychologists aren’t exactly sure what turns someone into a psychopath. A specific gene has been implicated, the so-called “warrior gene" The technical name is the MAOA-L gene.
