Eric Ries writes about his experience in achieving diversity in hiring by masking identifying information from the résumés (emphasis mine):
Now, whenever I screen resumes, I ask the recruiter to black out any demographic information from the resume itself: name, age, gender, country of origin. The first time I did this experiment, I felt a strange feeling of vertigo while reading the resume. “Who is this guy?” I had a hard time forming a visual image, which made it harder to try and compare each candidate to the successful people I’d worked with in the past. It was an uncomfortable feeling, which instantly revealed just how much I’d been relying on surface qualities when screening resumes before – even when I thought I was being 100% meritocratic. And, much to my surprise (and embarrassment), the kinds of people I started phone-screening changed immediately.
And yet, when I suggest this practice to hiring managers and recruiters alike, they rarely do it. Hiring managers say, “the recruiter would never go for it” while recruiters say, “the hiring manager won’t accept it.” What I think we’re really saying is: “I don’t want to know if I am biased.” That’s understandable – it’s embarrassing! Even if our biases are only implicit and not consciously held, the systems we build can still contain bias. When we change a hiring policy, especially if we do it in a visible way, we reap two benefits. We actually improve our hiring process and also signal our commitment to meritocracy.
