"So here’s an idea. Before we try to fix biases in hiring, maybe we should ask if we really have a problem. Then let’s try not to make it worse."

So, Margaret sites an Australian experiment where resumes with identifying information actually resulted in a bias towards hiring minorities and women..this is likely as a result of affirmative action programs imposed because of biases the other way in previous years.
Given this, why wouldn't Margaret be all in favour of the planned name- blind recruitment pilot project?  By her own statements in her article current practices favour women & minorities so it needs fixing.  She should love the name-blind approach if she is really in favour of un-biased hiring.
