US companies caught in diversity, equity, and inclusion (DEI) controversies often respond with highly visible gestures to repair their image. But new research suggests these actions amount to little more than “DEI-washing,” with limited meaningful change in hiring or workplace culture.

The study, conducted by accounting scholars from Stanford, Yale, the University of Chicago, and the University of Washington, examined how firms react after facing public scrutiny over DEI issues. It found that while companies tend to hire more diverse employees in the aftermath, the increases are minor and concentrated in roles with minimal influence on core business operations.

“We show that in the years following such controversies, firms hire more diverse employees. However, these effects are economically small, with an approximate 0.81% increase relative to a sample average of 58.9% diverse new hires,” the researchers wrote.

Notably, most of these hires are at junior or administrative levels, such as interns or HR staff, rather than leadership or decision-making roles. The study also found a slight rise in diverse employee departures, i.e., about 0.75% relative to a 58.3% average, leaving the net diversity gain marginal.

Stock Prices Take a Hit

Beyond workforce composition, DEI controversies also hit companies where it hurts most: The stock market.

“These events lead to both short- and long-term drops in stock prices,” the study noted. Companies typically see a negative abnormal return of around 0.72% in the days following an incident and underperform by about 3.5% annually over the long term.

However, firms that take meaningful steps to improve diversity, such as sustained, genuine hiring reforms, appear to mitigate these financial setbacks. Sufficient investment in DEI largely offsets these adverse financial effects, the study added.

DEI-Washing: Signals Without Substance

Despite the clear business case for real action, many companies choose optics over outcomes. The study describes this as “DEI-washing,” when firms issue statements or set targets without backing them up with tangible improvements.

After controversies, companies often talk more about diversity in official communications. DEI mentions in proxy statements jump by 17.6%, while references in CSR reports and corporate social media posts rise by 16.1% and 11.5%, respectively. The likelihood of setting a diversity target increases by 3.0%.

Yet, these public signals rarely translate into lasting change. “Across all columns, we find no statistically significant relationship between the change in each signaling variable after a DEI controversy and a subsequent change in diversity hiring at the firm,” the authors noted.

Morale Suffers as Talk Outpaces Action

The gap between corporate messaging and actual practice may also harm employee sentiment. The research found that DEI controversies negatively impact morale, underscoring the risks of performative gestures.

Despite growing public and shareholder pressure, the study concludes that most firms “either dedicate limited resources to these issues or their efforts are largely ineffective.” When diversity improvements do occur, they tend to happen in areas where change is easiest and least costly.

For HR leaders and executives, the findings serve as a warning: stakeholders increasingly expect more than statements and symbolic hires. Without meaningful DEI reforms, companies risk reputational damage and long-term underperformance.
