However, empirical evidence does not firmly establish that hyperopic behavior exists exclusively with high self-control. While Tangney et al.’s (2004) research acknowledges the potential for too much self-control, their results do not empirically support negative consequences at the high end of the self-control spectrum. Specifically, Tangney et al. tested for curvilinear effects of self-control in domains such as psychological adjustments, relationships, success, and so forth and found no evidence of negative long-term consequences of high self-control. Their results therefore support previous accounts suggesting that self-control fail-ure stems from either underregulation or misregulation of one’s behavior, but not from overregulation (Baumeister, Heatherton, and Tice 1994; Carver and Scheier 1981). Thus, evidence that hyperopia occurs as a result of too much self-control is lacking, despite the conceptual similarities between the two concepts.
