The idea that an innate advantage was responsible for the significant over-representation of left-handers in professional sports gradually lost momentum following the works of (Wood and Aggleton 1989; Aggleton and Wood 1990; Grouios et al. 2000a). These papers analyzed interactive sports such as tennis and non-interactive sports such as darts and pool. They found there was a surplus of left-handers in the interactive sports, but not generally in the non-interactive sports. (One exception is golf where Loffing and Hagemann (2016, Box 12.1) noted that the proportion of top left-handed[1] golfers is higher than in the general population.) It was reasoned that any innate superiority should also bring left-handers into prominence in non-interactive sports and so alternative explanations were sought. The primary argument of (Wood and Aggleton 1989; Aggleton and Wood 1990) was that the prominence of left-handers in a given sport was due to the strategic advantages of being left-handed in that sport.
