In this week's World in Words podcast, we consider the so-called bilingual advantage.

The benefits of speaking two languages were barely researched until the 1960s. Now, hardly a month goes by without the publication of a new inquiry into the bilingual brain. One of the most influential of these studies found that bilinguals were more adept at staving off memory loss and other effects of the ageing brain. Researchers have also found other evidence of cognitive improvements among speakers of more than one language.

There has been pushback from scholars who don't trust the methodology of these studies, or have been unable to reproduce the results, resulting in a nasty academic standoff.

Catch our podcast: The World in Words Each week on The World in Words, Patrick Cox and Nina Porzucki tell stories about languages and the people who speak them. Subscribe

There is also the occasional study that claims that speaking more than one language may actually be a disadvantage.

So in the podcast, we checked out some opinion, both informed and uninformed. We also report from a couple of bilingual frontlines: places where there is both support for and resistance to bilingualism in their communities.
