Employment Statistics: Questions• Do women and minorities in physical sciences seek different types
of employment from men/non-minorities?
• For scientists in tenure-track positions at universities and colleges, are tenure rates the same for men and women, minorities and majorities?
• Are the reasons for unemployment and part-time employment the same?
• What are the median salaries of women and minorities vs men in physical sciences?

Results of studies from social psychology
Source: Spencer, S. J., Steele, C. M., & Quinn, D. M., 1999, "Stereotype threat and women's math performance," Journal of Experimental Social Psychology, 35(1), p. 13.
Stereotype Threat
Stereotype Threat Condition: participants are told that the test had shown gender differences in the past.
Reinforcing stereotypes can create real differences in performance.

Different StandardsStudents’ Standards for Their Own Performance, by Gender
Source: Correll, S.J., 2004, “Constraints into preferences: Gender, status, and emerging career aspirations,” American Sociological Review, 69, p. 106, Table 2.
Respondents were asked: “How high would you have to score to be convinced that you have high ability at this task?”
When participants are told “Men are better at this task,” women hold themselves to a higher standard.
Stereotypes can increase feelings of being “not good enough.”
Unconscious Bias
Even people who consciously reject negative stereotypes can still hold those beliefs at an unconscious level.
You can discover your own biases at: https://implicit.harvard.edu/implicit/demo/
We will be hosting an expert in this field, Dr. Abby Stewart, here at JHU who will give a talk on the subject at the end of March. Stay tuned!
Unconscious Bias: Studies• Search committee for assistant professor prefers Brian to Karen 2:1 even
though their application packages are exactly the same. (Steinpreis, Anders, & Ritzke (1999) Sex Roles, 41, 509)
• Mother (active in PTA) vs. non-mother applications evaluated as less competent, called back half as often, offered lower starting salaries. Father vs. non-father applications seen as more committed to paid work and offered higher starting salaries. (Correll, Benard and Paik (2007) American Journal of Sociology, 112 (5), 1297-1338)
• Letters of Recommendation show gender differences. Letters for women are shorter, have more references to personal life, and contain more “doubt raisers” such as: “It’s amazing how much she’s accomplished.” “It appears her health is stable.” “She is close to my wife.” (Trix & Psenka (2003) Discourse & Society, Vol 14(2): 191-220)
The End!
