Cancellare la fede in Dio e i pregiudizi nei confronti per esempio degli immigrati. Un gruppo di scienziati sostiene di essere riuscito nell’impresa. I ricercatori di un’università della California hanno individuato l’area del cervello dove nascono le ideologie. Una volta scoperta, sono riusciti a modificarla.
Come si può leggere sulla rivista Social cognitive and affective neuroscience, hanno bersagliato con la stimolazione magnetica la corteccia cerebrale frontale, specializzata nel rilevare i problemi pratici e risolverli.
Le "cavie umane" hanno subito lo "spegnimento" temporaneo del cervello. Conseguenza: queste persone hanno registrato una diminuzione delle loro credenze e sentimenti più positivi nei confronti di categorie sociali che prima del trattamento tendevano a discriminare.
