There is research by Barbara Fredrickson from the University of Michigan that shows if a work group in a company experiences a positive to negative interaction ratio of 13:1, the work group will be less effective. This implies that no one is willing to confront the real problems and challenges that are holding them back. Sometimes we need to confront a situation to move past it and, as we know, ignoring problems that stare us in the face doesn’t work. Negative interactions are necessary as long as they occur much less frequently than positive interactions.
