The underhand ape

ns_logoIN 2004, Benjamin Olken visited a road-building project in rural Indonesia. There was just one small section missing – a bridge over a stream – but the money had run out because of embezzlement, and construction abandoned. “By the time I got there, you could see where the road had been cleared and built, but the grass had completely grown back,” he says. “The road had fallen into decay…”

God-loving linguists

il_logoIN 1963 Barbara and Joseph Grimes sat down with their Huichol neighbours to discuss what to do about the bandits terrorising their remote community. It was clear to everyone that the Grimes themselves were the problem. Seeing Americans living there, at the southern tip of the Rocky Mountains, the bandits assumed the community was rich. The Grimes recognised that it would be best for everyone if they left…

Close inspection of their coloration and shapes revealed five distinct species. The graduate student couldn’t wait to deliver the news to his supervisor, Frans Witte, at Leiden University in the Netherlands. “The quality of the phone line was so horrible that I wasn’t sure he had understood that we had caught cichlids offshore again,” he recalls…

Soon after, Spanish investigators searching the area near one of the blasts discovered an abandoned set of detonator caps inside a plastic bag that bore a single, incomplete fingerprint. They immediately shared the clue with law-enforcement colleagues around the world. And on 6 May 2004, the US Federal Bureau of Investigation (FBI) arrested Oregon lawyer Brandon Mayfield, proclaiming that his print was a match…

Identifying humans

economist-logoWITH the construction of the railways in the 19th century, a new sociological phenomenon was born: the travelling criminal. Until then, police had relied on local communities to recognise a bad apple in their midst, but now the felons were on the move, wreaking havoc in communities which had no knowledge of their past and hence no reason to be wary. For law enforcers trying to contain the problem by sharing descriptions of known recidivists, it became imperative to answer one question: what is it that identifies someone as a particular person?
