By melding economics and engineering, researchers show that as social networks get larger, they usually get better at sorting fact from fiction. The rise of the Internet has sparked a fascination with what The New Yorker 's financial writer James Surowiecki called, in a book of the same name, 'the wisdom of crowds?: the idea that aggregating or averaging the imperfect, distributed knowledge of a large group of people can often yield better information than canvassing expert opinion.
