the article is poorly titled. It said that Born agains and non religous had smaller hippocampus’ than non born again protestants.
Not smaller brains, instead, a portion that is not as large as another, which also begs the question of what portions may be larger?
No, they titled it that way deliberately - for those who never actually read the articles.
Seems to me I remember the nazis had all sorts of similar "studies" to justify their ostracization of the jews.
