An experiment on Stanford international relations students during the Cold War provided a cautionary tale about relying on kind-world reasoning — that is, drawing only from the first analogy that feels familiar. The students were told that a small, fictional democratic country was under threat from a totalitarian neighbor, and they had to decide how the United States should respond. Some students were given descriptions that likened the situation to World War II (refugees in boxcars; a president “from New York, the same state as FDR”; a meeting in “Winston Churchill Hall”). For others, it was likened to Vietnam, (a president “from Texas, the same as LBJ,” and refugees in boats). The international relations students who were reminded of World War II were far more likely to choose to go to war; the students reminded of Vietnam opted for nonmilitary diplomacy. That phenomenon has been documented all over the place. College football coaches rated the same player’s potential very differently depending on what former player was likened to an introductory description, even with all other information kept exactly the same.
