Males showed a tech tilt bias, and females showed an academic tilt bias. The tilt biases persisted after controlling for general intelligence
Tech tilt correlated negatively with academic abilities on the college aptitude tests (SAT, ACT, PSAT), with larger effects for females. In addition, relations of tech tilt with STEM jobs and majors were generally larger (and more often significant) for males, but only for tech tilt based on technical and verbal abilities. The negative relations of tech tilt with academic abilities on the college aptitude tests are consistent with investment theories, which predict that investment in one ability (technical) comes at the expense of competing abilities (academic). The sex differences in tech tilt and STEM support trait complexes involving abilities, interests, and vocational preferences (e.g., people versus things).
