" It’s useful to contrast the missileers’ dysfunctional culture with that of their navy counterparts who work in nuclear submarines. At first glance, the two groups seem roughly similar: Both spend vast amounts of time isolated from the rest of society, both are tasked with memorizing and executing tedious protocols, and both are oriented toward Cold War nuclear deterrence missions whose time has passed. Where they differ, however, is in the density of the belonging cues in their respective environments. Sailors in submarines have close physical proximity, take part in purposeful activity (global patrols that include missions beyond deterrence), and are part of a career pathway that can lead to the highest positions in the navy. Perhaps as a result, the nuclear submarine fleet has thus far mostly avoided the kinds of problems that plague the missileers, and in many cases have developed high-performing cultures. "
