The Evidence Gap
The corporate diversity, equity, and inclusion industry generates approximately $9 billion in annual revenue. That figure encompasses consulting fees, training programs, assessment tools, and the salaries of an estimated 75,000 full-time DEI professionals employed by American corporations.
What does $9 billion buy? According to a comprehensive meta-analysis published in the Journal of Applied Psychology last year, the answer is: very little that's measurable.
The study examined 40 years of diversity training research across 1,100 organizations. Its findings were stark: mandatory diversity training produced no sustained improvement in either workforce composition diversity or measures of workplace inclusion. In some cases, it produced backlash effects — increased intergroup resentment and decreased willingness to engage across demographic lines.
The Quiet Retreat
The corporate retreat from DEI is well underway, though few companies announce it publicly. Forty-three Fortune 500 companies reduced their DEI staff by 20% or more in 2025. Eleven eliminated their Chief Diversity Officer positions entirely. And the language has shifted — "DEI" is being rebranded as "belonging," "culture," or simply folded back into HR departments where similar functions existed before the 2020 expansion.
What's notable is who's retreating and who isn't. Companies facing competitive pressure — those in manufacturing, energy, and technology — are leading the drawdown. Companies insulated from market competition — utilities, government contractors, and heavily regulated industries — are maintaining or expanding their programs.
The market is sorting. And the market, as it tends to do, is choosing effectiveness over ideology.
What Actually Works
The research on what actually improves workplace diversity and inclusion is clear, though politically inconvenient for the consulting industry. Structured interviewing processes. Blind resume reviews. Mentorship programs with measurable outcomes. Transparent promotion criteria. These interventions are inexpensive, evidence-based, and effective.
They're also boring. They don't require two-day off-site workshops. They don't generate recurring consulting revenue. And they don't provide the organizational theater that allows executives to demonstrate their commitment to social values without changing anything structural.
The distinction between genuine inclusion efforts and the diversity industry is the same as the distinction between medicine and snake oil: one is based on evidence, and the other is based on belief.
The Accountability Question
Nine billion dollars annually. No measurable outcomes. In any other industry, this would be called fraud. In the diversity industry, it's called progress.
The companies that will thrive are the ones that care about results rather than credentials, merit rather than metrics, and genuine workplace culture rather than compliance theater. The data is clear. The question is whether corporate leadership has the courage to follow it.
