Point I want to make is, people are different starting from blood type, height, weight to "n" number of parameters and we can get different graphs for different parameters but that won't conclude anything.
Each person is different and just because some one belongs to a category does not make that person any extra attractive for any job.
In my personal opinion, this type of validation rather than competence,track record,experience is not beneficial to organization or society and completely shortsighted. So please stop these generalizations like "women are so and so", "men are so and so" ...etc. There are good and bad elements in every category.
