In honor of Mental Health Awareness Month, BET.com’s “How ‘They’ Built This” series is delving into two unsung heroes of the psychology world who’ve both shifted culture and built a lasting legacy in the process. This week, we’re digging into the work of the Clarks, the Black psychologists who were both a brilliant team and a loving power couple.​

In the 1940s, long before “mental health” became a buzzword, Dr. Mamie Phipps Clark and Dr. Kenneth Bancroft Clark were doing groundbreaking work. They asked Black children a simple question: Which doll looks like you? The results from that study helped dismantle legal segregation, set a new precedent for our mental health, and reshaped how psychology understands race, identity, and the harm racism leaves in its wake.

Mamie Phipps Clark was born in Hot Springs, Arkansas, in 1917 and grew up navigating Jim Crow while excelling in school. Kenneth Bancroft Clark, born in 1914, was raised in Harlem, New York, in a neighborhood buzzing with Black cultural and political life.

The two studied at Howard University, where they earned their bachelor’s and master’s degrees in psychology and met as students. Mamie’s master’s dissertation at Howard, “The Development of Consciousness of Self in Negro Pre-School Children,” came from her work at an all-Black nursery school and focused on how young children understood themselves as Black in a hostile society.

The couple went on to Columbia University, where they each broke barriers as they earned doctorates in psychology, becoming the first African Americans to receive PhDs in psychology from Columbia.

Building on Mamie’s early research on racial identity, the Clarks designed what became famous as the “doll tests.” They showed Black children, ages roughly 3 to 7, four identical dolls—two with light skin, two with dark skin—and asked which doll was “nice,” which was “bad,” and which looked most like them.

The pattern was devastating: many children called the white dolls “good” and the Black dolls “bad,” and some chose the white doll as the one that looked like them, even when their own skin tone was darker. This was psychological proof that segregation and racism had already taught children to see whiteness as better and Blackness as lesser, damaging self-esteem and shaping identity at a very young age.

In 1947, Gordon Parks photographed the Clarks and their young participants for Ebony magazine, visually documenting the tests in Harlem for an article about a new clinic serving “problem kids” in the neighborhood. Those images, with Black children choosing white dolls after sharing a negative association with mirroring their likeness, were heartbreaking. They soon became a lasting symbol of the emotional toll of segregation.

The Clarks didn’t keep their findings in academic journals. In the early 1950s, NAACP attorneys, including Thurgood Marshall, called on them to present the doll test results in school desegregation cases like Briggs v. Elliott in South Carolina. Their testimony showed that “separate but equal” wasn’t just unfair on paper; it was psychologically destructive for Black children.

When the Supreme Court decided Brown v. Board of Education in 1954, the Court cited social science research—including the Clarks’ work—to argue that segregation gave Black children “a feeling of inferiority” that could affect them for life. One of the original dolls used in their studies is now preserved and displayed at the Brown v. Board of Education National Historical Park as a physical reminder of how research helped shift constitutional law.​

Beyond the courtroom, the Clarks pushed psychology and wellness into the community. In 1946, they founded the Northside Center for Child Development in Harlem. The center was described as the first full-time child guidance clinic in the area to provide psychological services, testing, and social work support for children and families. They focused on children who were often labeled “troubled” and approached them as kids navigating the layered stress of poverty, racism, and underfunded schools.

Their work at Northside helped normalize the idea that Black children deserved the same level of mental health care and educational support as anyone else—a radical stance at a time when mainstream psychology often ignored Black communities.

Kenneth's professional résumé reads like a list of firsts. He became the first Black professor to receive tenure at the City College of New York, the first Black president of the American Psychological Association, and the first Black person appointed to the New York State Board of Regents, which oversees education in the state.

Mamie, meanwhile, built a three-decade career researching child development and racial prejudice, publishing widely and shaping how psychologists study racial identity and self-concept. While history was often centered on Kenneth, Mamie’s work has increasingly been recognized. And she’s been seen as a theorist and researcher in her own right, not just a “supporting” figure.

Today, their legacy reaches far beyond one experiment. The doll tests anticipated modern conversations about representation, colorism, and internalized bias. Their insistence that racism harms mental health echoes in current debates over school equity, policing, and trauma-informed care.

When it comes to mental health centered on Black wellness, they are the blueprint. And it’s a testament to how our passions—when studied rigorously—can sometimes change our laws.
