 However, generalizations like, “Little Jimmy is happy every time he finds a dollar,” are ceteris paribus rules. People readily recognize exceptions: for example, we recognize situations in which Jimmy would probably not be happy even if he found a dollar, including some in which finding a dollar might actually make him unhappy. Rather than applying some additional or more complex rules that cover such situations, it is arguable that putting ourselves in Jimmy's situation and using “good common sense” alerts us to to these exceptions and overrides the rule. If that is correct, then simulation is acting as an overseer or governor even when people appear to be simply applying rules.
