HughPickens.com writes: In the world of Big Data, everything means something. Now Joe Pinsker reports that Cornerstone OnDemand, a company that sells software that helps employers recruit and retain workers, has found after analyzing data on about 50,000 people who took its 45-minute online job assessment, that people who took the test on a non-default browser, such as Firefox or Chrome, ended up staying at their jobs about 15 percent longer than those who stuck with Safari or Internet Explorer. They also tended to perform better on the job as well. Chief Analytics Officer Michael Housman offered an explanation for the results in an interview with Freakonomics Radio: "I think that the fact that you took the time to install Firefox on your computer shows us something about you. It shows that you're someone who is an informed consumer," says Housman. "You've made an active choice to do something that wasn't default." But why would a company care about something as seemingly trivial as the browser a candidate chooses to use? "Call centers are estimated to suffer from a turnover rate of about 45 percent annually (PDF), and it can cost thousands of dollars to hire new employees," says Pinsker. "Because of that, companies are eager to find any proxy for talent and dedication that they can."
