1992年11月），平克顿和艾布拉姆森问道：”一个消息灵通、情绪稳定的成年人能做出理性的决定去从事危险的性行为吗？“（第561页）。如果“理性”按照以下方式定义，他们的答案是肯定的。一个人面对三种性选择--禁欲、”安全性行为”和”危险性行为”--为每一种选择分配效用（u）和感染艾滋病毒的概率（p）。感染HIV被认为等同于感染艾滋病，这被认为具有高度负效用（uA）。当风险性行为的预期效用大于其他选项时（如果风险性行为的感知快感相对较大，而艾滋病毒感染的感知风险相对较小，则可能发生这种情况），理性行为者会选择风险性行为。简而言之，在平克顿和艾布拉姆森看来，如果一个人从事危险的性行为，这并不一定意味着他或她有自杀倾向，或者过去十年一直在冥王星度假，错过了充斥在大众媒体上的”安全性行为”信息。因为”预期效用”等式中的每一个术语本质上都是主观的，所以不可能问一个给定的选择是否客观理性。然而，通过考虑以下问题，可以扩展平克顿和艾布拉姆森的分析：首先，人们对自己感染艾滋病病毒的可能性的评估有多准确？第二，与其他类型的风险相比，感染艾滋病毒的风险如何？(For为了讨论这个问题，我将假定HIV感染是导致艾滋病的必要条件，也是充分条件。）如果人们系统性地低估了他们感染艾滋病毒的风险，
November 1992), Pinkerton and Abramson asked," Can a well informed, emotionally stable adult make a rationaldecision to engage in risky sexual practices?"(p. 561). Their answer is yes, if" rational" is defined in the following way. A person faced with three sexual options—abstinence," safer sex," and" risky sex"—assigns to each a utility (u) and a probability of becoming infected with HIV (p). Becoming infected with HTV is considered equivalent to contracting AIDS, which is assumed to have a highly negative utility (uA). When the expected utility of risky sex is greater than that of the other options (which can occur if the perceived pleasure of risky sex is relatively great and the perceived risk of HIV infection is relatively small), the rational actor opts for risky sex. In short, if a person engages in risky sex, this does not necessarily indicate, in Pinkerton and Abramson's view, that he or she is suicidal or has been vacationing on Pluto for the last decade and has missed the" safer sex" messages that pervade the mass media.Because each term in the" expected utility" equation is inherently subjective, it is not possible to ask whether a given option is objectively rational. It is possible, however, to extend Pinkerton and Abramson's analysis by considering the following questions: First, how accurately do people assess the probability that they will become infected with HIV? Second, how does the risk of becoming infected with HIV compare with other kinds of risk?(For the purposes of this discussion, I will assume that HIV infection is both necessary and sufficient to cause AIDS.) If people systematically underestimate their risk of HIV infection and
