Bilingual people are smarter
From the March 17 New York Times:
…[T]here is ample evidence that in a bilingual’s brain both language systems are active even when he is using only one language, thus creating situations in which one system obstructs the other. But this interference, researchers are finding out, isn’t so much a handicap as a blessing in disguise. It forces the brain to resolve internal conflict, giving the mind a workout that strengthens its cognitive muscles.
In other words, if you’re bilingual (or poly-lingual), you have to constantly decide what to call something (apple, pomme, manzana, ping guo?) and what language to speak when addressing others. The extra cognitive effort means you end up thinking more sharply and in a more aware way. Bilingual brains may also resist dementia better.
This makes me wonder how many of the current GOP candidates speak more than one language.
