Latest / Hiring & Firing with Fexingo: Recruitment, Performance, and Workforce Decisions / How a Blind Hiring Trial Cut Bad Hires by 40 Percent
Transcript
- Lucas: So back in early 2025, a mid-size marketing agency in Chicago called Bailey & Foster decided to run a blind hiring trial for their account manager roles. They stripped every resume of names, schools, graduation years, even the candidates' addresses. Luna: That's a pretty aggressive scrub. Did they keep anything beyond work experience? Lucas: They kept job titles, tenure at each company, and the bullet points describing responsibilities. But no names of universities, no GPA, no personal details. They ran this alongside their normal process for six months — two hundred and seventy candidates total. And the result: a forty percent drop in first-year attrition among hires made through the blind track. Luna: Forty percent is huge. But I'm curious — did the quality of candidates also change? Were they just picking safer bets? Lucas: That's exactly the question they asked. They measured performance ratings at six months and one year. The blind-hire cohort had slightly higher average ratings — about eight percent higher — and they were promoted at a similar rate. So it wasn't just retention; they were performing marginally better too. Luna: So blinding the resume actually improved outcomes across the board. Why do you think that is? Lucas: I think the biggest factor was reducing what behavioral economists call 'beauty premium' — not just looks, but pedigree beauty. When you see a candidate from a top-twenty university, or a name that signals a certain background, you unconsciously assume competence. Blinding forces you to evaluate the actual work history. Luna: Right. And that works especially well for roles where the work experience is the best predictor. Account management at an agency — you want someone who's managed client relationships, not someone who aced a marketing class. Lucas: Exactly. But here's where it gets interesting. The agency also tried blind hiring for a senior creative director position. And it backfired. Luna: Oh really? What happened? Lucas: They narrowed the candidate pool from seventy to five finalists using blind resumes. All five were strong on paper — years of experience, impressive portfolio bullets. But when they met them in person, three lacked the strategic vision the role required. See, for senior roles, the resume alone — even anonymized — doesn't capture how someone thinks about complex problems. Luna: So blind hiring works better for entry to mid-level roles, but less so for leadership positions where soft signals matter. Lucas: That's the pattern. The broader meta-analysis from Harvard Business Review in 2024 — they looked at twenty-seven studies — found that blind hiring reduces bias in initial screening, but the effect diminishes at higher organizational levels. One reason is that senior roles rely on network effects and reputation, which are hard to anonymize. Luna: And if you blind too aggressively, you might also strip out signals of resilience or grit. Like, if someone worked while going to school, that often shows up in their timeline. Lucas: That's a really good point. Bailey & Foster actually found that their blind process filtered out some candidates who had taken non-traditional paths — like someone who took five years to complete a degree while holding down a job. But the irony is, those candidates often outperformed in the role. So they ended up adding back a 'life experience' section that was optional for candidates to fill out. Luna: So they calibrated. That's smart — don't throw out the baby with the bathwater. Lucas: Right. And another finding from their trial: the biggest improvement from blind hiring came not from the resume stage, but from combining it with a structured skill assessment. They gave all blind-track candidates a simulated client brief and asked them to outline a campaign strategy in sixty minutes. That assessment, scored blindly by a panel, was a much better predictor of six-month performance than the anonymized resume alone. Luna: So the resume — blinded or not — is still a pretty weak signal. The real win is forcing yourself to evaluate what someone can do, not what they've done. Lucas: Exactly. And that's the deeper lesson: blind hiring isn't a magic bullet. It's a tool to reduce one specific type of bias in one stage of the funnel. But if you're not also fixing your interview process or your assessment criteria, you're just rearranging deck chairs. Luna: So if a listener wants to run their own blind hiring trial, what's the simplest way to start? Lucas: I'd say pick one role — ideally one you hire for frequently, like a customer support specialist or a junior analyst. Use a simple tool to redact personal details from resumes — there are free plugins for applicant tracking systems that do this. And commit to running it for at least three months or fifty candidates. Measure time to hire, diversity of shortlisted candidates, and six-month performance. Luna: And compare it to a control group — hire some roles the old way simultaneously. Lucas: Absolutely. Bailey & Foster's control group was essential. Without it, they wouldn't have known whether the improvement was due to blind hiring or just a stronger labor market that quarter. Luna: One thing I've been thinking about: doesn't blind hiring sometimes conflict with diversity goals? If you're trying to increase representation of underrepresented groups, blinding might actually hide the very signals you're looking for, like attending a historically Black college or being a first-generation graduate. Lucas: That's the big tension. Some companies have moved to 'semi-blind' approaches — they blind for the first round, but then deliberately surface diversity information in later stages to ensure they're not accidentally filtering out candidates they want to attract. The key is to be intentional about which biases you're trying to reduce and which signals you want to preserve. Luna: It's not one-size-fits-all. But the evidence is clear: most of us are worse at reading resumes than we think. And any process that forces us to focus on actual skills is probably an improvement. Lucas: Yeah. And you know, I think a lot of these conversations we have on the show — they're the kind that might change how someone approaches their next hire. If that's happened for you, or if you've gotten something out of episodes like this, there's a small way to help keep the show going. We deliberately don't run ads on these. If you want to support that choice, the link is buy me a coffee dot com slash fexingo. Luna: And it genuinely helps — we pour a lot of research into each episode, and knowing listeners find it useful is what keeps us doing it. Lucas: Exactly. Now back to the blind hiring story — one more thing that surprised me. After the trial, Bailey & Foster decided to keep blind resumes for all non-senior roles. But they also started using a 'skills-first' language filter on job descriptions to attract a broader applicant pool. Luna: How did that go? Lucas: They rewrote their job posts to focus on competencies instead of credentials — things like 'experience with CRM tools' instead of 'degree required.' Within six months, the diversity of their applicant pool increased by about thirty percent, and the quality of candidates, measured by their skill assessment scores, actually went up. Luna: So the lesson might be: blind hiring is one part of a broader shift toward skills-based hiring. It's not just about hiding information — it's about changing what you value. Lucas: Exactly. One concrete number I like: the same Harvard meta-analysis found that skills-based assessments are two to three times better at predicting job performance than unstructured interviews. That's a massive gap. So if you combine blinding with a good skills test, you're addressing two of the biggest sources of hiring error at once. Luna: And the cost is minimal — a free plugin and a one-hour test. Feels like a no-brainer. Lucas: Yeah. The main resistance is habit. Hiring managers are used to their gut feeling. But the data keeps piling up: gut feeling is a terrible predictor of actual job performance. Luna: I'd love to see a follow-up episode on how to design a good skill assessment without making it a burden on candidates. Lucas: That's a great idea. Let's put that on the list.
