When learning how to improvise for stage, you learn quickly that you MUST be kind in order to succeed. If you are not nice to your partners, then your scenes will fall apart. It's like the structure of improv was built to hold up only when and if people are being nice to one another. It is no surprise that some of the very basic building blocks of improvisation are: listening, agreement, putting others before yourself, empathy, trust and getting each other's back. Imagine running that checklist through your mind at work or in a social setting.
