"How to Think about 'Implicit Bias'" (Payne, Niemi, & Doris, Scientific American, October 2020)

Core Definition of Implicit Bias

What implicit bias is

  • Definition: The tendency for stereotype-confirming thoughts to pass spontaneously through our minds.

  • It happens to most people, including the authors.

  • It does not make someone a racist, sexist, or other "-ist" in the sense of conscious bigotry.

  • It means the brain is noticing patterns and making generalizations – the same processes that make people smart can also make them biased.

Key distinction

  • Implicit bias ≠ explicit bigotry.

  • People can feel they are being fair while still being influenced by implicit bias.

  • It sets people up to overgeneralize, sometimes leading to discrimination.


2. The Controversy Surrounding Implicit Bias

Criticisms from both sides of the political spectrum

Political orientation

Criticism

Right

Talk of implicit bias is just another instance of progressives seeing injustice under every bush

Left

Implicit bias diverts attention from more damaging instances of explicit bigotry

What has been lost in the debate

  • Heated debates have leaped from scientific journals to the popular press.

  • Two important misunderstandings need clarification.


3. First Misunderstanding: The Implicit Association Test (IAT) is Flawed, Therefore Implicit Bias Isn't Real

What the IAT shows

  • A majority of people taking the IAT show evidence of implicit bias.

  • Suggests most individuals are implicitly biased even if they don't think of themselves as prejudiced.

Legitimate limitations of the IAT

Limitation

Explanation

Low stability

If you take the same test a few weeks apart, you might score very differently

Small correlation with behavior

The correlation between a person's IAT scores and discriminatory behavior is often small

The Divining Rod Fallacy

  • Fallacy: Concluding that because a particular measure is flawed, the phenomenon itself is not real.

  • Analogy: Just because a divining rod doesn't find water doesn't mean there's no such thing as water.

  • Correct response: "What does the other evidence show?"

The mountain of other evidence (independent of the IAT)

Type of evidence

Finding

Perceptual illusions

White subjects perceive Black faces as angrier than white faces with the same expression

Weapons bias

Bias causes people to see harmless objects as weapons when in the hands of Black men

Affective priming

Dislike abstract images paired with Black faces

Response time tasks

Dozens of variants: most participants are faster to identify bad words paired with Black faces than with white faces

Conclusion: None of these measures is without limitations, but each shows the same pattern of reliable bias. There is a mountain of evidence – independent of any single test – that implicit bias is real.


4. Second Misunderstanding: IAT Scores Don't Predict Individual Behavior

The Palm Reading Fallacy

  • Fallacy: Expecting a psychological measure to tell you, as an individual, what your life holds in store.

  • Reality: Research psychologists are not usually in the business of palm reading.

What most psychological measures actually do

  • From aptitude tests to personality scales, most measures are useful for predicting how groups will respond on average, not forecasting how particular individuals will behave.

  • Example: Knowing an employee scored high on conscientiousness won't tell you much about whether their work will be excellent on a specific task. But across many tasks and many employees, conscientiousness predicts work quality.

What the IAT does well

  • Implicit bias researchers have always warned against using the IAT for predicting individual outcomes (e.g., how a particular manager will behave in job interviews).

  • What the IAT does predict: average outcomes across larger entities (counties, cities, states).

Empirical examples of IAT predicting group-level outcomes

Level of analysis

Finding

Metro areas

Areas with greater average implicit bias have larger racial disparities in police shootings

Counties

Counties with greater average implicit bias have larger racial disparities in infant health problems

Significance: These correlations matter – the lives of Black citizens and newborn Black babies depend on them.


5. Field Experiment Evidence for Real-World Discrimination

Implicit bias is not just a laboratory curiosity. Field experiments demonstrate that real-world discrimination continues and is widespread.

Finding

Magnitude

White vs. Black applicants with same resumes

White applicants get ~50% more callbacks

College professors responding to student emails

26% more likely to respond to "Brad" than "Lamar"

Physicians prescribing pain medication

Recommend less pain medication for Black patients than white patients with the same injury

Key observation about modern discrimination

  • Today, managers are unlikely to announce that white applicants should be chosen over Black applicants.

  • Physicians don't declare that Black people feel less pain than white people.

  • Yet the broad pattern of discrimination and disparities persists.

  • This pattern bears a much closer resemblance to implicit bias test results than to survey studies where most people present themselves as unbiased.


6. Why People Are Skeptical (A Psychological Explanation)

A simple reason

"It isn't nice to think we aren't very nice."

The comforting but false conclusion

  • When we don't consciously entertain impure intentions, it would be comforting to conclude that all of our intentions are pure.

  • Unfortunately, we can't conclude that: many of us are more biased than we realize.

Why this matters

  • Implicit bias is an important cause of injustice – whether you know it or not.


7. Key Analogies & Fallacies Explained

Fallacy / Analogy

Definition

Application

Divining Rod Fallacy

Concluding a phenomenon isn't real because a specific measure is flawed

IAT has limitations, but other evidence proves implicit bias is real

Palm Reading Fallacy

Expecting a psychological measure to predict individual outcomes like a palm reader predicts a person's future

IAT predicts group averages, not individual behavior

Pattern recognition → bias

The same brain processes that make people smart (noticing patterns, generalizing) can also make them biased

Explains why implicit bias is universal, not a sign of moral failure


8. Summary of Empirical Evidence Cited

Study type

Key finding

IAT (majority of takers)

Show evidence of implicit bias

Perceptual illusions

Black faces perceived as angrier than white faces with same expression

Weapons bias

Harmless objects seen as weapons when held by Black men

Affective priming

Abstract images paired with Black faces are disliked

Response time tasks

Faster to associate bad words with Black faces

Resume callback studies

White applicants get 50% more callbacks

Professor email response

26% more likely to respond to "Brad" than "Lamar"

Pain medication prescription

Less medication recommended for Black patients with same injury

Police shooting disparities (metro areas)

Greater average bias → larger racial disparities

Infant health disparities (counties)

Greater average bias → larger racial disparities


9. Key Quotes (for direct reference)

"This tendency for stereotype-confirming thoughts to pass spontaneously through our minds is what psychologists call implicit bias."

"That doesn't make you a racist, sexist or whatever-ist. It means your brain is noticing patterns and making generalizations."

"The same thought processes that make people smart can also make them biased."

"It doesn't follow from a particular measure being flawed that the phenomenon we are attempting to measure is not real. Drawing that conclusion is to commit the Divining Rod Fallacy."

"There is a mountain of evidence—independent of any single test—that implicit bias is real."

"Implicit bias researchers have always warned against using the tests for predicting individual outcomes—they've never been in the palm-reading business."

"It isn't nice to think we aren't very nice."

"Many of us are more biased than we realize. And that is an important cause of injustice—whether you know it or not."


10. Practical Implications for Intercultural Competence

Why this matters for intercultural studies

  • Implicit bias operates below conscious awareness – even well-intentioned, self-aware individuals can exhibit it.

  • Developing intercultural competence requires not just explicit attitude change but also awareness of and strategies to counteract implicit bias.

Key takeaways for educators and practitioners

  1. Don't rely on self-reports alone – people genuinely believe they are unbiased, but implicit measures reveal otherwise.

  2. Focus on systems and averages – individual IAT scores are noisy, but aggregate bias predicts real disparities.

  3. Implicit bias is not moral failure – it's a cognitive process. This reduces defensiveness and opens the door for change.

  4. Interventions should target both explicit and implicit processes – conscious reflection (storytelling, self-awareness exercises) plus structural changes (blind resume reviews, standardized protocols).
