The scores for men stay about the same. The conclusion reached was that women are made to improve their articles over time. Men are not.
If this conclusion was correct, women’s articles should take longer to review. When Hengel checked, she found it took an average of six months longer to review papers written by women.
Why does this matter? The longer a researcher has to work on one project, the less time they have to do new research. This results in fewer published works, and that can affect one’s job prospects. That goes double in the world of economic academia.
