In support of the argument that left-handedness is a marker for decreased survival fitness, in 1991 Coren and Halpern gave considerable weight to the results of their 1988 study in which right-handed baseball players were described as having lived about eight months longer than their left-handed peers. In their 1993 unsuccessful attempt to replicate this study, Fudin and colleagues cited certain difficulties with the sources of these data that led them to recommend a comprehensive third study which included only reliable data from the two current editions of the major sources of information on Major League baseball players, i.e., the 1993 editions of The Baseball Encyclopedia and Total Baseball. Following this suggestion, we measured the life spans of all baseball players, i.e., right-, left-, and mixed-handed players, for whom reliable data were available (N = 5441) and found that the relationship between handedness and longevity was not significant. Unlike Halpern and Coren we noted that right-handed players could be described as having lived about eight months less than their left-handed peers.
为支持左撇子是生存适应性下降标志这一论点，1991年科伦和哈尔彭十分重视他们1988年的研究结果，该研究称右撇子棒球运动员比左撇子同龄人寿命长约八个月。1993年，富丁及其同事试图重复这项研究但未成功，他们指出这些数据来源存在某些问题，因此建议进行全面的第三项研究，该研究仅纳入来自关于美国职业棒球大联盟球员信息的两个主要现行版本的可靠数据，即1993年版的《棒球百科全书》和《棒球全史》。遵照这一建议，我们测量了所有有可靠数据的棒球运动员（包括右撇子、左撇子和左右手混用的球员，N = 5441）的寿命，发现用手习惯与寿命之间的关系并不显著。与哈尔彭和科伦不同的是，我们注意到右撇子球员的寿命比左撇子同龄人短约八个月。
