" People tend to think of vulnerability in a touchy-feely way, but that’s not what’s happening,” Polzer says. “It’s about sending a really clear signal that you have weaknesses, that you could use help. And if that behavior becomes a model for others, then you can set the insecurities aside and get to work, start to trust each other and help each other. If you never have that vulnerable moment, on the other hand, then people will try to cover up their weaknesses, and every little microtask becomes a place where insecurities manifest themselves. "
