Personality Quiz Reveals Men and Women's Systemizing Traits on the Rise

Share Article

Results from, a Web site exploring the Empathizing-Systemizing personality theory, indicate that men's and women's systemizing quotients are higher than in the initial Baron-Cohen study. However, empathizing scores have fallen. Does this indicate that men's natural aptitude for systemizing is on the rise?

Survey results from differ from the original study completed in 2003. finds that both men and women's systemizing quotient (SQ) scores are higher, whereas empathizing quotient (EQ) scores are lower. Despite the differences from the original study, these results continue to support the male versus female brain theory offered by Professor Simon Baron-Cohen and his group.

This theory states that, on average, more men than women have a systemizing (or “male”) brain and more women than men have an empathizing (or “female”) brain. Nevertheless, Professor Baron-Cohen and caution against stereotyping, agreeing that the Empathizing-Systemizing tests indicates personality type and not gender.

Visitors to can take a personality quiz based on the Empathizing-Systemizing theory of the male versus female brain. This theory, first studied by Professor Simon Baron-Cohen at the University of Cambridge, England, defines these two distinct traits. Together with Sally Wheelwright and others, the researchers have continued to develop their theory. makes the personality quiz available to anyone who cares to take it ( Comparing results from Baron-Cohen and Wheelwright’s original study and, the following differences were observed:


SQ 61.2 Original study

SQ 71.0 (rise of 16%)

EQ 39.0 Original study

EQ 38.5 (decrease of 1%)


SQ 51.7 Original study

SQ 57.8 (rise of 12%)

EQ 48.00 Original study

EQ 45.5 (decrease of 5%)

It seems that (where individuals choose to complete the tests) has attracted respondents who are, generally, more “systemizing” than the original study group (a controlled group asked to complete the tests). This highlights the pitfalls of analyzing data that has been generated by respondents who self-select. In this case, the self-selection appears attractive to systemizers (a group more likely to be interested in categorizing their personality) and is not, in fact, at significant variance with the original study. It does not indicate that male systemizing tendencies are rising. A further study with a suitably controlled group might involve first asking the test-takers if they would have any inclination to complete the tests of their own volition. centers on the Empathizing-Systemizing theory of the male versus the female brain types and how this knowledge can be applied to life choices to make more informed decisions. Systemizers and empathizers can find information and resources related to education, educational programs, and career choices.
