Microaggression

A 1970 psychiatry term that stayed on the academic margins for 37 years, then became a campus rulebook in under a decade.

1 · Where it came from

Born at Harvard, built at Columbia

A Harvard psychiatrist coined the word. A Columbia counseling lab turned it into a checklist anyone could teach.

1970Chester Pierce, Harvard

Names subtle racial slights, as opposed to "macro" acts like lynching.

1973 →Mary Rowe, MIT

Builds on Pierce with “micro-inequities,” extending the idea to sex and other groups in the workplace.

2000Solórzano et al.

Plugs it into critical race theory.

2007Sue et al., Columbia

Three types, nine themes, dozens of examples.

2 · What it's built on

Thin evidence, deep political roots

We graded all 73 sources in the 2007 paper and traced where its key ideas came from.

Yes, two documented paths

Through critical race theory, whose founders name Communist theorist Antonio Gramsci among their sources, and through Paulo Freire's teaching method, which quotes Marx, Mao and Che Guevara.

One step removed

Both paths run through one cited paper, Solórzano et al. (2000). The rest of the 2007 paper rests on mainstream psychology.

3 · How it spread

Two booms, two different engines

Professors drove the first wave. Activists and administrators drove the second, with no new research behind it.

4 · The roles it assigns

Everyone got a role, and every role paid

The concept fits the drama triangle, a classic model of how conflict sustains itself. Tap a role.

ACCUSED RESCUER VICTIM roles flip when the accused objects

It thrived where Campbell & Manning predict: equal-status, well-administered places like elite campuses and HR departments, where complaints go to a third party.

5 · Peak leverage

Its power peaked before its popularity did

From 2014 to 2020 the word was written into training, evaluations and reporting systems. Its most potent use: relabeling political opinions as personal offenses.

The UC handout listed "America is the land of opportunity," "I believe the most qualified person should get the job" and "Affirmative action is racist." A policy debate became a conduct issue, and since offenses could be unintended, the speaker's meaning didn't count.

6 · Follow the money

The research is cheap. The enforcement is not.

Federal grants that mention microaggressions add up to about $78 million, mostly as one theme inside larger health and science-diversity grants. The training and administration that teach and police them run into the billions. Most of the money funds the Rescuer.

$78M

Federal grants mentioning microaggressions: NIH $38M (40 projects), NSF $26M (32 awards), other agencies $14M (4 awards).

45

DEI staff at the average Power Five university in 2021, 1.4 times its tenured or tenure-track history faculty (Heritage Foundation count).

~$8B

Yearly U.S. diversity-training spending, a widely repeated estimate with no primary source (a market study put all DEI services at $7.5B in 2020).

Where the dollars land

Log scale.

Research (evidence)Enforcement (Rescuer)

The pushback that lasted closed offices and mandates. Cutting research grants barely touches the concept; removing the enforcement layer removes the Rescuer.

How to read this. NSF and NIH figures are complete counts of awards whose title or abstract uses “microaggression(s),” from each agency’s award database (Nov. 2026): NSF at estimated total value, NIH as actual yearly awards. Most mention the term in passing; only a handful are about microaggressions. NIH’s total includes $8.3M for one year of an NIMH intramural office report. Other agencies come from award descriptions on USAspending.gov. The Miami project also had a 2019 planning grant; press tallies put the whole effort at $2.2M to $3.4M. The $8B training figure is an estimate widely repeated (CNBC in 2024 attributed it to Harvard Kennedy School researchers) without a published primary source; treat it as an order of magnitude, not a count.

Still to pull: private foundation grants, university DEI office budgets in dollars, and accreditation requirements that mandate training.

7 · Pushback and decline

The people it claimed to protect mostly disagreed

Pushback came in three waves: scientists, then polls, then laws.

"Is this offensive?" Share saying no

Cato/YouGov, Aug. 2017, 2,300 adults. ◆ = on the University of California training list (wording sometimes differs slightly).

BlackLatino

Cato Institute, 2017 (full report). The one phrase from the list that most Black respondents (68%) did find offensive, "You are a credit to your race," was also on the UC list.

What worked
  1. Going after the Rescuer. The lasting wins defunded the training and reporting machinery rather than arguing about feelings.
  2. Polling the people it claimed to protect. Cato’s finding that most Black Americans did not find the listed phrases offensive did more damage than any critic.
  3. Critics from inside. An Emory psychologist in a top journal couldn't be waved off as partisan.
  4. Laws, not orders. A 2020 executive order lasted four months. State laws keep stacking up: 14 in 2023–24, 14 more in 2025.
The other side says
  • Newer studies link microaggressions to measurable prejudice and to poorer mental health in recipients (Williams 2020).
  • Polls rate single phrases, not the cumulative effect of hearing them often.
