Based on Losada’s extensive mathematical modeling, 2.9013 is the ratio of positive to negative interactions necessary to make a corporate team successful. This means that it takes about three positive comments, experiences, or expressions to fend off the languishing effects of one negative. Dip below this tipping point, now known as the Losada Line, and workplace performance quickly suffers. Rise above it—ideally, the research shows, to a ratio of 6 to 1—and teams produce their very best work.
