then be folly to deny human nature, treating individuals as if they were a “blank
slate.”

To offer another defense of a different kind for dispositionism, we
know that different individuals respond in different ways to the same external
situation, so what is it within us that shapes behavior? A situationist could
respond, of course, that these differing individuals were previously exposed to
different situations, and that it was the situations that shaped the differing
dispositions and hence the differing responses. And so on. We could go on and
on this way, tracing the story of causation further and further back. In social
science this is called “infinite regression,” since we can keep on regressing
through history, tracing the causes of causes back through time.
This is a complexity we shall leave until the conclusion of this book to dis-
cuss fully, though for now what follows is a brief overview to provide context
for later content. For one thing, any good story has to start somewhere; we
cannot, for purely practical reasons, consider all of human history in explaining
an event. The Vietnam War was arguably caused in part from “overlearning”
the lessons of World War II, for instance; World War II, in turn, arose because
of the way European leaders had reacted to World War I. World War I, in turn,
was caused in part by misperceptions between the major powers of the time,
and so on and so on. In the comedy movie Airplane II, an oddball air traffic
controller Jacobs is asked for a briefing on the fate of a missing plane. “Jacobs, I
want to know absolutely everything that’s happened up till now!” his boss
Steven McCroskey demands. Jacobs gives a bizarre answer. “First the earth
cooled. Then the dinosaurs came but were too big and died and everything got
rotten and turned into oil and the Arabs bought Mercedes Benzes. . . .” And he
goes on in this vein.
In a sense, this is the “correct” answer—the coming and going of the dino-
saurs probably is relevant if one wanted to create a full causal history of
everything that has happened to that point in human history—but the reason
his response is humorous is that there is a lot that we take as “given” in
providing explanations; the character is violating the social norm that we
conventionally leave some things that are considered obvious out of a causal
explanation. We break into the causal chain, often without thinking about it,
and consider only the proximate or most recent causes of an event.
There is, however, an inherent “gray area” between the concepts of disposi-
tionism and situationism. As noted above, every theory can be characterized as
situationist, since our dispositions are partly shaped by the situations we hap-
pen to have experienced throughout our lives. But there are two important
points that must be made here: first of all, the reader should note that when we
characterize a theory as “dispositionist,” we mean only that dispositions affect
behavior in a proximate or immediate sense. Although our partisan identifica-
tions or our attitudes towards the use of military force may have been shaped
