array of scientific evidence in his conceptualization, for example, a correlation of .62 between cranial capacity and distance from the equator with 20,000 crania representing 122 ethnically distinguishable populations (Beals, Smith, & Dodd, 1984). Templer and Arikawa (2003) reported a correlation of .71 between mean IQ and mean high winter temperature and a correlation of .61 between mean IQ and mean low winter temperature with 129 countries. There are alternative explanations to those of Rushton for such findings. To relegate Rushton’s theory to the realm of absurdity, however, would neither constitute optimal scientific reasoning nor represent an ideal spirit of scholarly disagreement.
