I disagree. Unless one thinks that men are simply better law clerks than women, one would expect there to be an even distribution that is close to the general population (or at least the population of legal personnel out there to choose from)
I would be concerned if he had a statistically significantly greater percentage of women, because that would indicate something other than simple competence was involved (He prefers women around him in the workplace for whatever reason, or he is hewing to a PC line for PR by hiring more women)
Just my two cents...
Unless you can provide the info that ‘Sergio” hinted at, my argument is no different from yours. Statistical the same as the general population.
