Anything that claims to de-bunk Noam Chomsky is at least worth a look:

More than 25 years ago, Professor Everett, then a missionary and now an ethnologist at the University of Manchester, decided to try to teach members of the obscure Pirahã tribe how to count. He would not succeed. Instead, he found a world without numbers, without time, one where people appeared to hum and whistle rather than speak.

This isolated tribe of some 350 people in tiny villages in the depths of the Brazilian jungle could turn our understanding of language on its head and disprove the main work of one of the world's most celebrated intellectuals, Noam Chomsky.

Cultural anthropology, like pretty much all "classic" fields of scientific academia, is as much about political bloodsport as it is real research. A bomb this big thrown this hard will reverberate for quite some time before the dust settles and we really learn anything. The fact that this guy's been studying the Pirahã for, what, thirty years and only now seems to be reaching the popular press speaks volumes about how long a new idea has to fight in the knife-scraped alleyways of academic journals to see the light of day.

Eventually they do, although it typically takes a really sharp journalist or TV producer to popularize things to the point that non-professionals start to take notice.
