Introduction


Increasing the representation of women in science, technology, engineering, and mathematics (STEM) is critically important for the effective utilization of human capital and the sustained competitiveness of these fields. McChesney et al.1 demonstrated the discrepancy between the career interests of individuals they believed to be currently in or aspiring to computer science (CS) occupations and the average Occupational Interest Profile (OIP) for those occupations from the U.S. Department of Labor’s Occupational Information Network (O*NET). They cautioned that stereotypical descriptions of CS career interests could deter women from entering the field. While we share their view on the need to represent interest diversity within CS (and STEM occupations in general), we see the critical need to clarify the nature of the OIPs and point out that McChesney et al.’s analyses and conclusions were based on a heterogeneous set of jobs rather than CS occupations. Importantly, we suggest evidence-based practices for broadening the participation of women in STEM.

OIPs are not stereotypical descriptions of occupations

McChesney et al.1 characterized OIPs from O*NET as “inferred interests of job incumbents” and framed OIPs as “stereotypical depictions” of occupations. Despite containing the word “interest,” an OIP does not measure interests of job incumbents within an occupation; nor does it measure the stereotype about an occupation. Rather, an OIP was developed to reflect the extent to which Holland’s2 RIASEC work environments are descriptive and characteristic of core tasks and activities typically performed in an occupation3. These tasks and activities were also identified via a rigorous, systematic data collection process4. This distinction is important, because the purpose of the OIPs is to provide information at the occupational level that helps individuals understand the type of work involved in different careers so as to facilitate career exploration. Thus, the OIP for CS describes common tasks and activities incumbents do in CS, not the people in these occupations who may have diverse interests. By no means does the OIP represents the stereotypical interest profile of CS professionals. Characterizing the OIPs as stereotypical depictions of occupations may discourage individuals from using occupational information from O*NET, which provides the nation’s most reliable and useful resource for career exploration and job search.

Heterogeneity of jobs classified as computer science occupations

The focus of McChesney et al.1 was on what they called “CS professions”. However, their definition of CS professions was not well specified (“those requiring some form of experience in computing”) and the classification process was conducted by Amazon Mechanical Turk workers with no background or training in occupational classification. As a result, 21 out of the 46 job titles that were classified as “CS professions” in McChesney et al.1 belonged instead to 11 other occupational groups that are very different in nature, ranging from business/finance (e.g., “Marketing Specialists”) to arts/design (e.g., “Graphic designers”) to service occupations (e.g., “Gaming Supervisors”). Though some of these jobs may be tangentially related to computer science because of the use of computers in daily work (e.g., marketing specialists, graphic designers, desktop publishers), others are not related to computer science at all (e.g., gaming supervisors, which refer to personnel who supervise and coordinate activities of workers in gambling services).

In Table 1, we list these 21 jobs and their corresponding occupational categories based on the Bureau of Labor Statistics’ Standard Occupational Classification (SOC) system5,6. These jobs employed 344 out of the 500 participants whose interest scores were analyzed by McChesney et al.1. In other words, nearly 70% of the participants worked in jobs outside the field of computer science. Each of these jobs has an OIP that is distinctively different from that of CS. Many of them, including the examples highlighted above, have higher levels of Artistic, Enterprising, and/or Social characteristics. Thus, the latent interest profiles McChesney et al.1 developed based on this occupationally diverse sample reflected not the interests of “computer scientists” but the interests of individuals employed in a heterogenous set of jobs. Coincidentally, about 70% of their participants displayed interest profiles that deviated from what was deemed normative for CS job incumbents. For example, with a sizable proportion of the 500 participants employed in arts/design-related jobs, it is not surprising that an Artistic latent interest profile was well represented in the data. Therefore, the diverse interest profiles reported by McChesney et al.1 were, at least in part, due to the inclusion of a heterogeneous set of non-CS jobs and workers in the analyses.

Addressing key questions: interest diversity within occupations

McChesney et al.’s1 characterization of OIPs and CS occupations notwithstanding, they did pose an excellent question—that is, could individual career interests diverge from characteristics of the occupational environments they are in? The answer is yes. Research across over 100 occupations in the U.S. demonstrated high levels of diversity in individual interests within occupations7. In other words, although career interests are major drivers of individuals’ career choices and individuals are likely found in occupations that match their interests than not, many will have interests different from the types of interests their occupations typically fulfill. It is well expected that all individuals within an occupation will not share the same interest profile. Meanwhile, the level of interest diversity has also been shown to vary significantly across occupations7, with fine artists and physicists being some of the most homogenous and dietitians and chiropractors being some of the most heterogeneous. A more nuanced and comprehensive picture of interests in CS and other STEM fields would indeed be important, but it would need to be drawn from large, representative samples.

If interest diversity is expected among members within an occupation, is it still valid to provide career guidance to individuals based on the comparison of their career interests and characteristic descriptions of an occupational environment, such as the OIP? We argue that it is. Over a century of research on career interests and many large-scale studies and meta-analyses have shown that interest congruence—the extent to which individual interests match the characteristics of their occupational environments—is predictive of individuals’ job satisfaction, job performance, persistence on the job, and career success8,9,10. Without accurately understanding and characterizing occupational environments, individuals lack information to explore and choose occupations in which they are most likely to be satisfied and successful and most likely to stay. To discuss the diversity of individual interests within an occupation without considering the importance of interest congruence for these work outcomes can be misleading. In this regard, occupational information provided by databases such as O*NET and U.K.’s National Career Services and assessments of interest congruence based on such information offer invaluable guidance, rather than reinforcing stereotypes.

Closing the gender gap: a path forward

Considering substantial gender differences in career interests—particularly differences along the things-people dimension with females expressing stronger interests in working with people11,12, how do we address the fact that fewer girls and women may find their interests congruent with CS and other STEM fields? To broaden participation in STEM, one promising path forward is relational job design13. Organizations may incorporate people-oriented tasks and activities in the design of specific jobs and emphasize the prosocial impact of the jobs when recruiting candidates. Similarly, STEM educational programs can incorporate and highlight opportunities for people-oriented tasks and activities as a way to attract more girls and women with social interests and communal values14. At the individual level, initiatives designed to cultivate girls’ interest in STEM solve one piece of gender gap puzzle. Other potential interventions could aim to make science and math activities personally relatable, showcase real-world applications, highlight successful female role models, and help girls develop strong self-concepts in these areas15. These interventions would also need to occur early and be widely accessible to the public. An excellent example is “SciGirls”, a recent television series funded by the U.S. National Science Foundation, that features young girls performing hands-on scientific experiments with female scientist mentors. Programs like this supplement the rich information about occupational environments provided by databases such as O*NET to paint a realistic and yet accessible picture of what inclusive STEM careers are like.
