Abstract
We investigated the effect of having a nickname on the longevity of major league baseball players. Ages of death, birth year, and career lengths of major league baseball players who debuted prior to 1950 were obtained and we compared longevities of players with nicknames with those who did not have a nickname. After controlling for these factors in analysis of covariance, there was a statistically significant increase in longevity of 2.5 years associated with having a nickname. Players with nicknames (N = 2,666; 38.1%) lived an average of 68.6 (±15.1 S.D.) years compared to players without nicknames (N = 4,329; 61.9%) who lived an average of 66.1 (±16.1) years. We attributed this nickname-related effect on longevity to enhanced self-esteem.
