Virginia Hughes on the use of technology to reveal that J.K. Rowling was indeed Robert Galbraith, a critically-acclaimed supposed first-time author:
Of all of the tests he can run with his program, Millican finds these word usage comparisons most compelling. “You end up with a graph, and on the graph it’s absolutely clear that Cuckoo’s Calling is lining up with Harry Potter. And it’s also clear that the Ruth Rendell books are close together, the Val McDermid books are close together, and so on,” he says. “It is identifying something objective that’s there. You can’t easily describe in English what it’s detecting, but it’s clearly detecting a similarity.”
On all of Millican’s tests, Cuckoo turned out to be most similar to a known Rowling book, and on four of them, both Rowling books were closer than any of the others. Millican got the files around 8pm on Friday night. Five hours later, he emailed the Sunday Times. “I said, ‘I’m pretty certain that if it’s one of these four authors, it’s Rowling.’”
And this can work on any of us.
