  1. Do left-handers die sooner than right-handers ? Commentary on Coren and Halpern's (1991) "Left-handedness : a marker for decreased survival fitness".

    Article - En anglais

    Cross-sectional life span studies of handedness typically show decreasing percentages of left-handers in older age groups.

    In an article in Psychological Bulletin, S. Coren and D. F. Halpern (1991) argued that this age trend reflects the shorter life span of left-handers than right-handers.

    They presented 2 studies of their own providing what they regard to be direct evidence that left-handers, on average, die sooner than right-handers.

    They also proposed a variety of reasons for what they called left-handers « decreased survival fitness ».

    I discuss Coren and Halpern's reasons for rejecting a more conventional explanation of the life span data.
