Recurring theme on this sub: a screenshot of average matriculant stats by demographic group, an implicit “the system is unfair,” and no engagement with the published evidence. As an incoming orthopaedic surgery resident with a clinical research background, here is what the literature actually shows. Links throughout.
- MCAT and GPA predict standardized test performance. They do not predict clinical performance and were never validated against patient outcomes.
- Saguil et al. 2015 (Military Medicine, USU Long-Term Career Outcome Study, n=340): MCAT correlated weakly-to-moderately with Step 1, weakly with Step 2 CK and Step 3, and not significantly with OSCE clinical skills, Step 2 CS subscores, or PGY-1 program director evaluations of physician performance. https://academic.oup.com/milmed/article/180/suppl\_4/4/4210177
- Southern Illinois standardized-patient validity study: correlations of MCAT/GPA with clinical performance were weak, and no admissions metric consistently predicted clinical skill. https://pubmed.ncbi.nlm.nih.gov/2751790/
- Even the AAMC’s own validity defense rests on academic and licensing-exam outcomes, not patient care quality. https://www.aamc.org/news/how-well-does-mcat-exam-predict-success-medical-school
Translation: a 515 vs a 508 tells you who will do better on the next multiple-choice exam. It does not tell you who will be a better physician. The metric was never validated for that purpose.
The “merit” frame ignores enormous structural advantages that have nothing to do with race.
• 2025 scoping review confirms admissions globally favor higher-SES applicants; in the UK roughly 80% of accepted medical applicants had parents in high-status professions. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12577556/
• US-specific: roughly three-quarters of medical students come from the top two household-income quintiles. Admissions reward access to physician relatives, paid MCAT prep ($2–5k+), paid research, and unpaid clinical/shadowing hours, all of which track wealth. https://pmc.ncbi.nlm.nih.gov/articles/PMC9662240/
• Physician-legacy applicants are overrepresented; the medical education literature has explicitly described legacy preferences as unethical and counterproductive given workforce needs. https://journals.stfm.org/primer/2023/kunes-2023-0071/
If you are upset about a thumb on the scale in admissions, the heaviest one is socioeconomic and legacy-based, and it primarily benefits high-income applicants of all races. It almost never gets a stats screenshot.
Workforce diversity has measurable downstream patient-outcome effects. This is the part that should settle the “but what about quality” objection.
• Frakes & Gruber, NBER, Military Health System (a quasi-experimental design using base reassignments): a one-SD increase in share of Black providers produced a ~15% relative decline in Black mortality among patients with chronic, manageable conditions, with most of the effect mediated by improved preventive medication use. https://www.nber.org/papers/w30767
• Greenwood et al. 2020, PNAS, 1.8M Florida births: under Black physicians, the Black newborn mortality penalty was roughly halved relative to under white physicians. https://www.pnas.org/doi/10.1073/pnas.1913405117
• 2023 work covered in STAT: higher county-level density of Black primary care physicians is associated with longer Black life expectancy. https://www.statnews.com/2023/04/14/black-doctors-primary-care-life-expectancy-mortality/
• URM physicians (Black, Hispanic, Native American) are consistently more likely to practice primary care and to serve in underserved and shortage areas. https://pmc.ncbi.nlm.nih.gov/articles/PMC5871929/
These are not vibes. They are causal or quasi-causal designs with patient mortality as the outcome.
