From NBC News: “”Allen v. Farrow” highlights a highly contentious theory known as “Parental Alienation Syndrome,” promoted by psychoanalyst Richard Gardner in 1985 to describe mothers who brainwash kids into turning against fathers in custody disputes. Though Gardner’s work is rejected by the scientific community, U.S. courts still sometimes use it.”
