In what at least one critic has dismissed as the Dunning Krueger Effect in action, Pastor John MacArthur of Grace Community Church in Sun Valley, California, claims there is no such thing as mental illness.
More than one in five U.S. adults live with a mental illness, according to the U.S. Centers for Disease Control and Prevention. Over one in five youth (ages 13-18) either currently or at some point during their life have had a seriously debilitating mental illness. About one in 25 U.S. adults also lives with a serious mental illness, such as schizophrenia, bipolar disorder, or major depression.
