Age is probably a more important factor than gender. Moreover, lab vs life discrepancy appears to be a big issue in cognitive abilities research.

Abstract: Adult age differences in a variety of cognitive abilities are well documented, and many of those abilities have been found to be related to success in the workplace and in everyday life. However, increased age is seldom associated with lower levels of real-world functioning, and the reasons for this lab-life discrepancy are not well understood.
