This article assumes that changes in the way the brain handles verbal responses are due to an inevitable “physical maturation.” I wonder to what extent these brain changes (and many others) are a side effect of literacy and what exactly are the trade-offs for learning how to read and write. This study could be made […]

GENES, ONCE HYPOTHETICAL, NOW SEEN AND PHOTOGRAPHED Genes, the ultimate units in heredity, have been seen and photographed.

Your article reports that, after infancy, humans have trouble recognizing facial differences between members of other species. Many of us commonly observe that people of other races than ourselves “all look alike” to us. Could this stem from lack of early exposure to others? Anecdotally, my wife, raised in a multiracial environment, has far less […]

From a psychological perspective, the antidote to depression involves increasing experiences of nurturance and hope in a person anticipating a future that’s empty and depleting. What’s a placebo but food that a depressed person hopes will fix things? Could it possibly […]
