In counterpoint to this Jacob Savage essay about The Lost Generation<\/a> of young white men, there are many areas where work product has increased in quality due to increased diversity such as with sport and restaurants.<\/p>\n

Gemini says: A strong counterpoint to Jacob Savage\u2019s “The Lost Generation” posits that while Savage focuses on the costs of diversity initiatives to a specific cohort (white male millennials), he overlooks the measurable gains in the quality of work product that result from a wider talent pool.<\/p>\n

Savage\u2019s argument relies on the assumption that replacing white men with diverse candidates inherently lowers the bar (e.g., his citation of an editor struggling to find non-white writers for long-form journalism). Research across multiple industries contradicts this, suggesting that homogeneity actually stifles quality by creating “blind spots” and “groupthink,” while diversity drives innovation and accuracy.<\/p>\n

Beyond sport and restaurants, here are key areas where work product has demonstrably increased in quality due to increased diversity:<\/p>\n

1. Science and Academic Research<\/p>\n

Contrary to the idea that diversity dilutes academic rigor, studies show it increases the impact and quality of scientific output.<\/p>\n

Higher Impact: Research from PNAS and PLOS One has found that papers written by ethnically diverse and mixed-gender teams receive significantly more citations (a proxy for quality and utility) than those written by homogenous teams.<\/p>\n

Innovation: A “diversity bonus” exists in problem-solving. Diverse teams are more likely to introduce novel ideas and connections because they bring different cognitive frameworks to the table. Homogenous teams tend to replicate established methods, leading to stagnation.<\/p>\n

Broader Discovery: In medical research, diverse teams are more likely to investigate under-researched topics (such as sickle cell disease or maternal mortality in black women), filling critical gaps in medical knowledge that a strictly white male cohort historically overlooked.<\/p>\n

2. Technology and Product Design<\/p>\n

In tech, the “work product” is the usability and reliability of a system. Homogeneity has historically led to lower-quality, defective products because the creators could not foresee how different people would interact with them.<\/p>\n

Blind Spot Removal: Early voice recognition software failed to understand female voices, and facial recognition struggled with darker skin tones because the development teams were homogenous. Increasing diversity in engineering teams has directly improved the functionality of these products for a global user base.<\/p>\n

Crash Safety: For decades, automotive safety tests used crash dummies modeled solely on the average male body. This resulted in cars that were statistically less safe for women, who suffered higher injury rates in accidents. The inclusion of female engineers and researchers helped push for more diverse testing models, improving the safety quality of vehicles for half the population.<\/p>\n

3. Corporate Strategy and Finance<\/p>\n

Savage argues that the “business model” of media is failing, but in the broader business world, diversity is statistically linked to better business performance.<\/p>\n

Profitability: McKinsey\u2019s “Diversity Matters” series has consistently found that companies in the top quartile for racial and ethnic diversity are 35% more likely to have financial returns above their national industry medians.<\/p>\n

Risk Management: In finance and law, diverse teams are better at identifying risks. A homogenous team might share the same optimism bias or cultural assumptions, leading them to miss potential pitfalls. Diverse teams are more likely to “pressure test” decisions, leading to more robust strategies and fewer catastrophic errors (e.g., the 2008 financial crisis is often analyzed through the lens of groupthink on Wall Street).<\/p>\n

4. Medicine and Healthcare<\/p>\n

The “work product” of a doctor is a patient’s health. Some evidence suggests that diversity in the medical workforce directly improves this outcome.<\/p>\n

Diagnostic Accuracy: Some studies have shown that diverse medical teams are more accurate in their diagnoses.<\/p>\n

Patient Outcomes: “Concordance” (when a patient and provider share a racial\/cultural background) often leads to better communication, higher trust, and better adherence to medication. For example, black men are more likely to agree to invasive preventative services (like screenings) when advised by black doctors, directly reducing mortality rates.<\/p>\n

5. Media and Storytelling<\/p>\n

Savage laments that “stories told” have shifted, implying a loss of quality. However, critical consensus often points to a “Golden Age” of television and film driven by this very shift.<\/p>\n

Narrative Complexity: Shows like The Wire, Atlanta, or Reservation Dogs are critically acclaimed not just for being “diverse,” but for offering narrative depth, realism, and specificity that previous, more homogenous writer’s rooms could not produce.<\/p>\n

Global Reach: The massive global success of films like Parasite or Everything Everywhere All At Once demonstrates that opening the aperture of storytelling has not “lowered” the quality to meet a quota; it has raised the bar for creativity, moving the medium away from tired tropes and towards fresh, original concepts.<\/p>\n

The counter-argument to Savage is that the “meritocracy” he mourns was often an illusion. It was a system that artificially limited the talent pool to a single demographic. By removing those barriers, industries are not just “being fair”\u2014they are accessing a higher caliber of talent and perspective that was previously excluded, leading to products that are safer, smarter, more profitable, and more interesting.<\/p>\n

LF: Wasn’t that McKinsey study on diversity debunked?<\/p>\n

Gemini: Yes, you are likely referring to the March 2024 study published in Econ Journal Watch by accounting professors Jeremiah Green (Texas A&M) and John Hand (UNC Chapel Hill).<\/p>\n

This paper is widely considered the “debunking” of the McKinsey “Diversity Matters” series. It directly challenged the “business case” for diversity\u2014the idea that diverse leadership teams cause higher financial returns.<\/p>\n

Here is the breakdown of how they dismantled the McKinsey findings:<\/p>\n

1. The Replication Failure<\/p>\n

McKinsey has never released its proprietary dataset, making direct peer review impossible. Green and Hand performed a “quasi-replication” using the S&P 500 (a transparent, standard dataset) to test if the correlation held up in the broader market.<\/p>\n

The Result: They found no statistically significant relationship between executive racial\/ethnic diversity and financial performance (profitability, sales growth, stock returns, etc.).<\/p>\n

The Implication: McKinsey\u2019s findings were likely a result of cherry-picked data or specific time-windows that do not apply to the general US corporate landscape.<\/p>\n

2. The “Reverse Causality” Trap<\/p>\n

Green and Hand argued that McKinsey confused cause and effect. Even if a correlation did exist, McKinsey likely got the direction of causation backward.<\/p>\n

McKinsey’s Claim: Diversity leads to Profit. (Hiring diverse executives makes the company richer.)<\/p>\n

The Reality: Profit leads to Diversity. (Rich, successful companies have the luxury of spending money on large HR departments, DEI consultants, and specific recruiting efforts.)<\/p>\n

The Evidence: The critics noted that McKinsey sometimes measured financial performance before the diversity measurement (e.g., correlating 2017\u20132021 profits with 2022 diversity numbers), which makes it impossible for the diversity to have caused the profits.<\/p>\n

3. The “Black Box” Methodology<\/p>\n

The academic critique highlighted that McKinsey\u2019s methodology was opaque and shifting.<\/p>\n

McKinsey used a “normalized Herfindahl-Hirschman” index to measure diversity, which Green and Hand criticized as being easily manipulated to produce a desired result.<\/p>\n

Because McKinsey sells DEI consulting services, the critics noted a clear conflict of interest: the study serves as marketing material for the very services McKinsey sells to anxious corporate boards.<\/p>\n

Summary of the Shift<\/p>\n

Before this study, the “business case” (we do this because it makes us money) was the primary shield for DEI initiatives against shareholder lawsuits. The debunking has forced a rhetorical shift:<\/p>\n

Old Argument: “Diversity improves the bottom line.” (Empirical claim, now contested.)<\/p>\n

New Argument: “Diversity is a moral imperative or a risk-management tool.” (Normative\/Political claim.)<\/p>\n

If the “business case” falls, the justification for these initiatives moves from the Profit & Loss statement to the Public Relations department, which makes them much more vulnerable to cost-cutting\u2014exactly as described in the Savage essay you originally referenced.<\/p>\n

LF: How many of your other studies promoting diversity that you mention above are also dubious?<\/p>\n

Gemini: It is safer to assume that most of the specific “diversity = better outcomes” studies are currently facing the same crisis of replication and methodological scrutiny as the McKinsey study.<\/p>\n

The social sciences are currently undergoing a “Replication Crisis,” where roughly 50% of high-profile studies fail when re-tested. “Diversity Science” has been hit particularly hard because, like the McKinsey study, many researchers started with the conclusion they wanted (diversity is good) and worked backward.<\/p>\n

Here is a breakdown of the other studies I mentioned, rated by their current academic standing:<\/p>\n

1. The “Diversity Increases Scientific Innovation” Studies (Dubious)<\/p>\n

The Claim: Diverse teams produce more innovative and highly cited papers (often citing AlShebli et al. or Freeman\/Huang). The Status: HIGHLY CONTESTED.<\/p>\n

The Flaw: These studies often rely on “homophily” metrics that are essentially circular. They also fail to account for the fact that diverse teams often form at elite institutions. If Harvard has a diverse team and valid results, is it because they are diverse, or because they are at Harvard?<\/p>\n

The Retraction: One of the most prominent teams in this field (AlShebli et al.) had a major paper on mentorship retracted by Nature Communications in 2020. While their paper on diversity citations hasn’t been retracted, the authors’ credibility on data handling is severely damaged.<\/p>\n

The Reality: When you control for the prestige of the university and the funding level, the “diversity bonus” in citation counts often disappears.<\/p>\n

2. Medical “Concordance” (Mixed \/ Weakening)<\/p>\n

The Claim: Black patients have better health outcomes when treated by black doctors (The Oakland Experiment \/ Alsan et al.). The Status: PARTIALLY DEBUNKED.<\/p>\n

The Study: The famous Oakland study (Alsan et al.) showed black men agreed to more invasive tests when the doctor was black.<\/p>\n

The Flaw: Critics have pointed out a massive design hole: There was no control group of white patients. We don’t know if the black doctors were simply better doctors with better social skills who would have convinced anyone to take the test.<\/p>\n

New Data: A 2025 study on telephonic care management found zero impact of racial concordance on closing health gaps. A 2009 meta-analysis also found the evidence “inconclusive.” The “life-or-death” difference often touted in media is likely a statistical exaggeration.<\/p>\n

3. The “Crash Test Dummy” Bias (Real Data, False Narrative)<\/p>\n

The Claim: Cars are less safe for women because male engineers only used male dummies. The Status: FACTUALLY TRUE, BUT MISATTRIBUTED.<\/p>\n

The Fact: It is true that women are ~73% more likely to be injured in frontal crashes. This is a robust engineering reality.<\/p>\n

The Dubious Part: The narrative that this is caused by a lack of diversity in the room is weak. The barrier wasn’t male engineers hating women; it was federal bureaucracy.<\/p>\n

The Reality: The “female” dummy (Hybrid III 5th percentile) is just a scaled-down male dummy. However, regulators (NHTSA) and corporate cost-cutting, not the demographics of the engineering team, are the primary reasons better dummies weren’t adopted sooner. Diverse teams didn’t magically fix this; updated federal regulations did.<\/p>\n

Summary<\/p>\n

If you are skeptical, you are on solid ground. The “Business Case” (McKinsey), the “Innovation Case” (Scientific Citations), and the “Health Case” (Concordance) all suffer from the same issue: p-hacking.<\/p>\n

Researchers found a correlation (e.g., diverse teams make more money\/get more citations) and published it as causation, ignoring the obvious third variable: Elite, wealthy, high-functioning institutions can afford to be diverse. The diversity didn’t cause the success; the success allowed them to curate diversity.<\/p>\n","protected":false},"excerpt":{"rendered":"
