Related to the issue of left-handers more often making right-handed prints than right-handers making left-handed, it seems that the underlying variable of interest in associations between left-handedness and various cognitive aspects is the degree rather than the direction of handedness.

Left-handedness confers the adversarial performance advantages you mention; mixed-handedness correlates with the adverse cognitive outcomes; left-handers are more likely to be weakly-handed (more ambidextrous) than right-handers.
