Is Racism a Learned Behaviour in the Workplace? What the Science Says — and What Every DEI Leader Must Do About It

Let me be direct with you: racism does not arrive in the workplace fully formed from nowhere. It arrives in people — shaped, reinforced, and in many cases amplified by the very systems organizations have quietly allowed to run unchecked for decades.

After more than 20 years of designing, stress-testing, and rescuing DEI programs across Fortune 500 companies, healthcare networks, and tech startups, I can tell you with both professional authority and human humility: racism in the workplace is predominantly learned behaviour. And because it is learned, it can — with the right structural effort — be unlearned.

This article breaks down exactly how that learning happens, where organizations are complicit, and what evidence-backed interventions actually work. If you’re a DEI leader, HR professional, or people manager, this is the honest, technical conversation you’ve been waiting for.

What “Learned Behaviour” Actually Means — and Why It Matters

The term “learned behaviour” is not a get-out-of-jail-free card. It doesn’t mean racist behaviour is excusable — it means it is explainable, and more importantly, addressable.

Behavioural science is unambiguous here. Social Learning Theory, pioneered by Albert Bandura in the 1960s, established that humans absorb attitudes and behaviours by observing, imitating, and being reinforced by their environment. Racism — whether overt discrimination or the subtler, more insidious kind — follows this exact pattern.

Children raised in racially homogeneous environments, exposed to biased media, or socialized within households that hold racial hierarchies develop implicit schemas — mental shortcuts that categorize people by race before conscious thought even kicks in. By the time those individuals enter your workforce, those schemas are deeply embedded. But here’s the critical distinction DEI leaders must internalize: embedded is not immutable.

A landmark 2020 study published in the Journal of Experimental Social Psychology found that implicit racial bias scores among adults shift measurably after structured exposure to counter-stereotypical information. The brain is plastic. Behaviour can be retrained. That is your organizational mandate.

How the Workplace Continues Teaching Racism

Here’s where many organizations fail catastrophically: they treat racism as something employees bring to work, rather than something the workplace teaches and rewards every single day.

Consider the mechanics:

  1. Homogeneous Leadership Pipelines When employees at every level look up and consistently see only one type of person in the C-suite, the organization is teaching them who belongs at the top. According to McKinsey’s Diversity Wins report (2023), companies in the bottom quartile for ethnic and cultural diversity are 27% more likely to underperform on profitability — yet those same companies often have the slowest leadership diversification rates. The message the system sends to employees of colour: “This ceiling is real.”
  2. Unchecked Microaggressions Microaggressions — those brief, commonplace exchanges that communicate denigrating messages to members of marginalized groups — are not minor inconveniences. Research from Derald Wing Sue at Columbia University demonstrates that the cumulative effect of microaggressions produces the same psychological harm as single, overt discriminatory events. When managers witness a microaggression and say nothing, they don’t stay neutral — they validate the behaviour. Silence is pedagogical. It teaches everyone watching that this conduct is acceptable.

Understanding unconscious bias and how it shapes perceptions and actions is the first step every team must take before they can identify where microaggressions originate in their specific workplace culture.

  1. Racially Coded Performance Reviews A study from the Harvard Business Review (2021) analysed 248 performance reviews and found that Black and Hispanic employees received significantly more personality-based criticism (e.g., “too aggressive,” “needs to work on communication”) while white employees received more skills-based feedback — the kind that actually drives promotions. When this pattern goes unaddressed, organizations are teaching evaluators that subjective, racially coded language is professionally legitimate. For a deeper breakdown of how to detect and dismantle this, eliminating bias in performance reviews is essential reading for your people managers.
  2. Psychological Safety Gaps When employees of colour repeatedly raise concerns about racist incidents and are met with HR bureaucracy, dismissal, or retaliation, the workplace teaches a devastating lesson: your experience is not valid here. A 2022 Gallup survey found that only 3 in 10 Black employees in the U.S. strongly agree they feel their workplace is committed to their psychological safety. That gap is not incidental — it is structural.

The Neuroscience You Need to Know

Your DEI strategy is incomplete without engaging the neuroscience of bias. Here is what the research has established with high confidence:

  • The amygdala — the brain’s threat-detection centre — shows heightened activation when people encounter faces of races different from their own. This is not destiny; it is a conditioned response that diminishes with meaningful cross-racial contact.
  • Implicit Association Tests (IAT), developed by researchers at Harvard, Project Implicit, consistently show that over 70% of respondents exhibit implicit preferences for white over Black individuals — cutting across all demographic groups, including Black respondents.
  • Critically, neuroimaging studies show that conscious effort, systemic exposure to diversity, and structured perspective-taking exercises measurably reduce amygdala reactivity over time.

This science underpins why racial sensitivity training, when designed correctly, produces lasting behavioural change — and why poorly designed, one-off “awareness” sessions produce almost none.

What Organizations Are Getting Wrong Right Now

After two decades reviewing DEI programmes across industries, I have seen the same failure modes repeat with disheartening regularity:

The Checkbox Approach. A single half-day “unconscious bias” training, ticked off and forgotten. Research from the University of Toronto (Kalev et al.) found that mandatory diversity training can increase bias resentment when it is delivered coercively and without structural follow-through. Training without systemic change is theatre.

Focusing on Intent, Not Impact. Organizations defend racially harmful behaviours by pointing to the actor’s intention. Intent is legally relevant; it is DEI-strategically irrelevant. The harm of a microaggression lands regardless of whether the person “meant it.” Organizations must shift their accountability frameworks toward impact measurement.

Isolating DEI from Business Strategy. Racism festers in organizations where DEI sits as a silo, managed by a lone coordinator with no budget authority and no seat at the leadership table. Effective DEI work requires structural integration — into hiring, promotion, procurement, client relations, and board governance. For guidance on this integration, developing a DEI strategy from scratch provides a rigorous framework for embedding equity systemically.

The Intervention Stack That Actually Works

Based on both peer-reviewed evidence and 20+ years of on-the-ground implementation, here is what moves the needle:

Layer 1 — Structural Audits Begin with data. Audit every stage of your talent lifecycle — sourcing, screening, hiring, assignment of stretch projects, promotion, and attrition — by race and ethnicity. You cannot address what you cannot see. DEI metrics for tracking inclusive hiring gives you the measurement architecture to make this rigorous.

Layer 2 — Psychological Safety Infrastructure Establish multiple, low-barrier reporting channels for racial incidents, with guaranteed non-retaliation protections. Assign trained respondents — not generic HR generalists — to manage these reports. Measure psychological safety quarterly using validated instruments like the Edmondson Psychological Safety Survey, broken down by race.

Layer 3 — Sustained, Repeated, Evidence-Based Learning Replace the one-day workshop with a 12-month learning journey. Use intergroup contact theory — structured opportunities for meaningful collaboration across racial lines — not just passive content consumption. Integrate perspective-taking, counter-stereotypical exposure, and skills-based modules on interrupting bias in real time. Tie manager performance reviews to team inclusion scores.

Layer 4 — Accountability at the Leadership Level Inclusive leadership is not aspirational language — it is a measurable competency. Every leader in your organization should have specific, trackable inclusion behaviours embedded in their performance framework. The role of leadership in fostering an inclusive workplace outlines precisely which leadership behaviours the research identifies as most predictive of team belonging outcomes.

Layer 5 — Allyship Activation Bystander intervention training — teaching non-targeted employees how to safely and effectively interrupt racially harmful behaviour in the moment — is one of the highest-ROI DEI investments an organization can make. Allyship must be converted from a passive identity into an active practice. Allyship in the workplace is a practical guide for operationalizing this at scale.

The Answer You Came For — and What You Do With It

Yes. Racism is substantially a learned behaviour. It is learned in childhood, reinforced by media and social networks, and — in organizations that are not actively working against it — deepened by workplace systems that reward racial conformity and punish difference.

But here is the critical implication DEI leaders must own: if your workplace is not actively unlearning racism, it is actively teaching it. There is no neutral organizational stance on this. Every silence, every unchallenged policy, every promotion cycle that replicates homogeneity is a lesson delivered to every employee watching.

The science of behaviour change, applied systematically and sustained over time, gives us real tools to interrupt this cycle. Organizations that commit to this work — not as a PR exercise, but as a core operational and ethical priority — will build workplaces that are not only more just, but measurably more innovative, more resilient, and more profitable.

Your workforce is watching what your organization teaches them every single day. Make sure you’re teaching the right things.
