High RWAs tend to feel more endangered in a potentially threatening situation than most people do, and often respond aggressively. In 1987 my colleague Gerry Sande and I had five-man teams of male introductory psychology students role-play NATO in an “international simulation” involving (they thought) another team of students playing as the Warsaw Pact. Some of the NATO teams were composed entirely of low RWA students, and other NATO teams were stocked entirely with highs. (We experimenters secretly played the Warsaw Pact.) The simulation began with a couple of ambiguous moves by the Warsaw Pact, such as holding military exercises earlier than anticipated, and withdrawing divisions to rear areas (possibly for rest, or --as Dr. Strangelove might argue--possibly for redeployment for an attack). The NATO teams could respond with nonthreatening or threatening moves of varying magnitudes. But if they made threats, the Warsaw pact responded with twice as much threat in return, and the NATO team would reap what it had sown as an escalation of aggressive moves would likely result. The low RWA teams did not interpret the ambiguous moves at the beginning of the game as serious threats and thus seldom made threatening moves. The high RWAs on the other hand usually reacted to the opening Warsaw Pact moves aggressively, and sowed a whirlwind. Over the course of the simulation, the high RWA teams made ten times as much threat as the low teams did, and usually brought the world to the brink of nuclear war.
