It is a pretty good article, but it slightly misunderstands status. Being the first person on the dance floor is closer to a high status move, because it is taking a leardership position and suggesting what the group should do next. People avoid doing that because they want to copy someone of a higher status than themselves, not because they fear low status. The mechanism nature uses to implement that low status behaviour is nervousness which is often described as a fear of "standing out", "looking silly" or similar terms, but those are low status concerns. High status people don't really suffer from looking silly, they define what looking silly is by being what they don't do.
