Whenever job evaluation, promotion or effectiveness occurs in the assessment of work, the results should include job performance rather than gender bias. The United States is facing major social problems related to gender bias and gender discrimination. Sexual segregation is an act that directly violates state, federal, or local law. Discrimination based on gender is illegal and prejudiced. Prejudice is legal, but individual stereotypes based on gender may lead to lack of confidence and lower confidence in ability.
Our own research focuses on engineering and law. We have developed a tool called Workplace Experience Survey to test race and gender bias in business systems such as work. In the nationwide survey, our Work Life Legal Center and the Women's Engineers Association provided over 3,000 engineers with early versions of the study. Compared with colleagues, women report that they are 29% more likely to do chores than white men. Our research shows that there are race dynamics in task differences. When we survey lawyers nationwide, colored women are most likely to report more administrative work than their colleagues - 20% higher than white men. Compared to white men, white women report that the possibility of performing more management tasks is 18% higher. For housekeeping such as cleaning coffee cups, the likelihood is most likely to say that colored women are more than colleagues - 18% more than white men
Efforts to verify or refute the existence of gender bias in the company is enormous. The most obvious way of isolating gender bias is laboratory experiments conducted in academia, where they study differences in product evaluation of work (especially in the field of male domination). Basically, research participants were asked to rate the same individuals (from paper, online or from film) other than sex. Therefore, scientists repeatedly record the differences seen in the evaluation of these fake candidates due to gender bias (see here and here).
