Speaking at Davos this week, Wharton professor and author Adam Grant relayed one anecdote about how Glen Mazzara, executive producer of “The Shield” and formerly of “The Walking Dead,” dealt with male writers’ attempts to keep female writers from contributing during discussions: a no-interruptions rule. According to Grant, it worked. “Lo and behold, it seems to be much more useful for women than men,” he said. “Because women are usually the people who get interrupted. I think that’s an example of a policy we can all put in place.”
