freeman wrote a commentary for nature about how implicit bias hinders the careers of lgbt people in science, technology, engineering, and math (stem) fields, and yet this group is often left out of diversity initiatives. he identified that lgbt people in stem are less represented than expected, reporting negative workplace experiences, and leaving stem fields at a high rate. realising the importance of comprehensive data, he led a collaborative effort with the support of 17 scientific organisations asking the national science foundation to include questions about sexual orientation and gender identity in their national stem workforce surveys. lgbt data from these surveys is critical for researchers and policymakers to be able to understand and address potential disparities and disadvantages of lgbt people in u.s. stem fields. the national science foundation is currently piloting these questions for future surveys.
