"We see this sort of architecture - this gorgeous use of the small world property - in the national power grid, in the Internet, in the human brain and in the genome," Strogatz says. He says it's important to remember that Milgram was not being deceptive in his original study, and describes the small world property as a sort of "universal architecture" of connection - both in the outside world and in the biology of the human body. Steven Strogatz, a professor of applied mathematics at Cornell University, disputes this claim. "The idea of 'six degrees of separation' may, in fact, be plain wrong - the academic equivalent of an urban myth." "Milgram's startling conclusion turns out to rest on scanty evidence," she says. Judith Kleinfeld, a professor of psychology at the University of Alaska, researched Milgram's original experiment in the hopes of updating it for the digital world. The result that entered the public imagination was that, in general, it took six steps or fewer to bridge the gap between any two people. The well known "six degrees of separation" idea traces back to a 1967 experiment by Stanley Milgram, who tried to determine how many acquaintances it would take to pass a letter between two randomly selected people.
