Provide a 600 word commentary.

In particular, pay attention to the words of Peter Hegarty in the article who says he is “optimistic” about the revelation of gender bias in psychology because it shows that the system of psychological research “works”:

. . . an area where more critical thinking is needed about gender, but on the other hand psychological methods allowed us to bring this issue to light and to describe it. Our conclusion is not that psychologists should not study group differences, but that we serve the public better when we think deeply about the ways that we implicitly frame questions about whose behavior is the default standard norm and whose is made the subject of psychological scrutiny.

Does a profound gender bias continue to exist in psychological research? Does knowing that psychology has tried, but failed, to deal with gender bias make a person more or less confident in the findings of psychology?
