It is suggestive, and I'd love to see the study carried out with a larger sample size and a control for reviewer harshness. The results certainly beg for that.

My company used to have a division that did technical job placement. We'd interview technicians, select a subset of good candidates, and then place them at firms who were looking at temp work. Hiring organizations selecting based off of perceived gender (via name) was definitely an impression we all got. And then there were the outright racists who'd tell us that they were "all set for diversity candidates" which is racist HR-speak for "don't send us any black people."

Shit like that, the study above, and just having two eyeballs are among the reasons why I still support affirmative action. It's a horribly inelegant solution to a very intractable problem, but at the end of the day I know that as a white male, I'm going to get those bonus "20 points" that a minority candidate enjoyed on their college application back when I enter the job market. I don't say that to gloat or be flippant, -it disgusts me, but it's reality.
