I recently had the opportunity to see Jared Diamond, Pulitzer Prize-winning author of Guns, Germs, and Steel, speak on his new book, The World Until Yesterday: What Can We Learn from Traditional Societies.
The book鈥檚 premise is that we have much to learn from traditional societies鈥攖hat is those that are not WEIRD: 鈥淲estern, Educated, Industrialized, Rich, and Democratic.鈥� The only traditional societies left today are in New Guinea (where Diamond has studied extensively) and the Amazon Basin. He argues that by studying these cultures, we can improve our health and wealth.
An entire chapter is devoted to the importance of bilingualism and multilingualism, and the development and spread of languages. In traditional societies, multilingualism was (and is, for the very few that remain) widespread. While many in the West fear that our children will be confused if they are exposed to more than one language at a time, kids in traditional societies begin learning additional languages from birth鈥攁nd not just one or two. Diamond can鈥檛 think of a single person he has met in New Guinea that speaks fewer than five languages (and yes, they are all 鈥渕utually unintelligible languages,鈥� not dialects). In Europe since the end of World War II, there has been a re-emergence of multilingualism, which Diamond attributes to economic and political integration, as well as universal education, and the 鈥渟pread of English language mass media.鈥�
Here in the U.S. we bask in the luxury of English as the language mass media and of business. Of course that means we are missing out on understanding other cultures鈥攖hey get us but do we get them? Denmark, as the seventh richest country in the world, doesn鈥檛 shun the learning of a second language鈥攖hey value the speaking of Danish, English, and other European languages as tools for conducting business.
Diamond offers a socio-economic argument for multilingualism, too. 鈥淕roups whose language and culture disintegrate tend to lose their pride and mutual self-support, and to descend into socio-economic problems,鈥� writes Diamond. To see this, we don鈥檛 have to look any further than our own Native American population. For centuries the government insisted that they be taught in English and prohibited from learning their native languages. Repeatedly they have been told their languages and cultures are worthless. The result? They are among the poorest segment of our society. Why not try valuing culture and language instead? Diamond points to bilingual Cherokee who are more likely to pursue their education, get jobs, and make more money than those who don鈥檛 learn Cherokee. Encouraging these types of programs would be a cheaper and much more valuable contribution to society.
There are large direct benefits for bilinguals鈥攖o start, they have a much larger vocabulary, 6,000 words (for example 3,000 in English and 3,000 in Mandarin). Another is improved 鈥渆xecutive function鈥� or cognitive control. Whatever you are doing right now鈥攕ay, reading this post鈥攜ou have to focus on while suppressing the other 99% of thoughts fighting for priority in your head. This is what allows you to focus on problem solving, moving between tasks, and recalling words and information. (Are you tired of hearing all of these terms after the past two weeks of PISA coverage?) Monolingual people may have an easier time calling up a word because they have a smaller vocabulary to file through. But bilingual people must keep their languages separate and know which stock to call upon at the right moment in the right conversation. This may sound like a detriment鈥攁ren鈥檛 bilinguals slower on the draw?
Studies have shown this is not true. Bilinguals are always unconsciously using their executive control, every time they think, listen, and speak. Therefore, they are constantly practicing this skill and improving upon it鈥攍ike an athlete or artist. Diamond shares studies demonstrating that the skill these bilinguals are practicing is the solving of problems鈥攕pecifically problems with rules that are confusing or constantly changing or where misleading information is involved. I don鈥檛 know about you鈥攂ut that sums up half of my life!
And another benefit suggested by recent studies is that life-long bilinguals will experience a delay of 4 to 5 years in the onset of Alzheimer鈥檚 disease. For a disease that leads to death in 5 - 10 years after onset, this is huge. For many people this fact alone may be the deciding factor in raising their child to be bilingual.
This work is really interesting, not just as another argument for studying other languages, but also as a reason to study other cultures. Sometimes we need a new lens through which to view the world鈥攅ven if it is not new at all and comes from traditions we have collectively forgotten. I encourage you to read The World Until Yesterday and open yourself up to a new, yet somehow familiar, perspective.
