Why 89% of hiring failures have nothing to do with skill

In 2012, Leadership IQ published a landmark study: Why New Hires Fail. Researchers tracked 5,247 hiring managers across 312 organizations over three years, following 20,000 new hires through their first 18 months on the job. Their conclusion was stark: 46% of those new hires failed within 18 months.

That number alone is alarming. But the follow-up finding is what companies consistently ignore: 89% of those failures were caused by attitude, motivation, temperament, and cultural fit issues — not technical skill.

Only 11% failed because they couldn't do the job technically.

The interview problem

The typical interview process is almost perfectly designed to evaluate the wrong things. You spend 45 minutes assessing whether a candidate can talk about their technical skills, answer situational questions they've rehearsed, and present a polished version of themselves under low-stakes conditions.

What you don't get is any reliable signal about coachability — whether they can take feedback without becoming defensive. You don't measure emotional intelligence under pressure. You don't evaluate how they handle ambiguity, disagreement, or failure. And you almost never get a read on whether their actual values align with your culture, as opposed to whether they can articulate what your values are.

Worse, the signals you do receive from interviews are systematically biased toward people who are good at interviewing — which correlates with extraversion, preparation, and privilege, not job performance.

What the research actually recommends

The Leadership IQ findings align closely with decades of industrial psychology research. Schmidt and Hunter's 1998 meta-analysis — still the most replicated finding in the field — showed that structured, rubric-anchored evaluations predict job performance at roughly twice the rate of unstructured interviews.

The key word is structured. Not just asking the same questions to every candidate (though that helps). Structured evaluation means:

• Scoring dimensions defined in advance — not based on gut feel after the fact
• Evidence-anchored scoring — points tied to specific observable behaviors, not impressions
• Consistent rubrics — the same criteria applied to every candidate for the same role
• Auditable decisions — the ability to explain why you chose candidate A over candidate B

When hiring managers know they'll have to defend their decision, and they have a rubric to do it with, outcomes improve dramatically.

The cultural fit dimension

"Cultural fit" has become a dirty phrase in hiring — and understandably so. Used loosely, it's a cover for affinity bias, discrimination, and hiring people who look and think like the existing team.

But dismissing cultural fit entirely is a mistake. The Leadership IQ data is clear: attitude, motivation, and values alignment are the primary drivers of new hire failure. The problem isn't assessing cultural fit — it's how it's typically assessed: loosely, subjectively, and after a 45-minute conversation.

Structured cultural evaluation — mapping a candidate's public digital footprint, written work, and stated values against documented company values using a rubric — can make cultural assessment both more predictive and more defensible than an interview-based feel.

What this means for how you hire

The implication isn't that technical skill doesn't matter — it obviously does. The implication is that your current evaluation process is probably screening hard for the thing that causes 11% of failures while mostly ignoring the things that cause the other 89%.

The fix isn't a longer interview process. It's a different kind of evaluation: one that generates structured, rubric-anchored evidence about attitude, coachability, and values alignment — alongside technical competence.

That evidence needs to be documented, auditable, and independent of who was in the room and what kind of day they were having. That's the standard Chesky was built to meet.
