I was recently at a conference on the science of psychology and mental health treatment. I was struck by the number of women in attendance compared to the number of men. Women outnumbered the men three to one. But the women were largely sitting in the audience—while the men were standing at the podium, lecturing. This experience led me to, once again, ponder questions about gender and equality in mental health and psychology. It also led me to question how we define mental health given the lower level of participation by women than men in creating that definition.
