People who can speak a second language sometimes like to point to research that shows bilingualism appears to make you smarter (or at least means you perform better in certain cognitive tasks). If I were bilingual I’d probably feel smug too. The problem is, however, that lots of other studies show bilingual people perform no better than us more linguistically challenged folk. Even the evidence that learning another language changes your brain structure presents a mixed picture.
So what’s going on? A new generation of research has shown that bilingualism can come in many different forms. And its wider effects likely depend on exactly how you learn and use your different languages. This is helping us build a much clearer picture of exactly what being bilingual means for your brain.
Another area where there doesn’t appear to be a scientific consensus is in the response to the pandemic. Danny Dorling writes that what to do about COVID-19 has divided many scientists into rival camps – and their combative rhetoric is no good for anyone.
And, meanwhile, Hollywood looks set to do particularly badly from the pandemic because its absence from international screens is paving the way for other countries’ film industries to flourish.
