Explaining gay men\u27s unrealistic optimism about becoming infected with HIV

Among the self-justifications that gay men use when deciding to have unprotected intercourse is the thought that they are at less risk than most gay men. Two explanatory models of such \u27unrealistic optimism\u27 (UO) have been proposed: while the motivational account holds that UO serves the function of bringing comfort, the cognitive account holds that UO serves no particular function, being simply a by-product of normal cognitive strategies. This study tested the prediction, derived from the motivational account, that highlighting the salience of the self-other comparison should increase UO. Gay men uninfected with HIV (n = 122) estimated both their own risk of contracting various health problems - among them, becoming infected with HIV - and that of the average gay man. The purported aim of collecting the data was varied, so as to either make the self-other comparison central to the aim or render one of the two types of estimate irrelevant to the aim. No effect on UO was found. It seems that the cognitive account provides a better explanation than does the motivational account of at least that form of UO measured in this study. Implications for AIDS education are discussed.
