Justin Trudeau promised evidence-based policy when he became PM. I see little evidence in Minister Duncan's article. "How is it that women make up approximately half of those earning their PhDs in the sciences and yet account for less than a quarter of full-time professors?" Is she referring to women who recently earned their PhDs and full-time professorships filled over the same timeframe, or is she referring to women who recently earned their PhDs and professorships filled over the last three decades? Does the less than one-quarter represent 1% of female applicants, or 100%? So, are women really under-represented? Why were the less than one quarter successful? Did they have better credentials? Was their research of greater commercial interest? The Minister makes passing reference to the disabled, indigenous people and minorities. Perhaps there is more than one reason for their lack of success. Perhaps there are reasons other than the presumably WASP phallocratic hierarchy.
