There is no evidence that any of this will successfully transfer from the lab to the real world. Even if it does, it would violate therapists' code of conduct, and could have unforeseen consequences.
“Lying to children is a slippery slope that makes me uncomfortable,” says Judy Illes, a neuroethicist at the University of British Columbia in Vancouver, Canada. “Can't we alter their behavior in a positive way, instead of using subterfuge?” But Loftus dismisses the concerns, suggesting that even if therapists cannot do it, parents might want to. “Parents lie to their kids all the time, about Santa Claus and the tooth fairy. Would you rather have an unhealthy kid, or one with a few false memories?”
