How Our Hand Gestures Reveal Our Cultural and Racial Identities

Duke research shows how people talk with their hands differently

A study conducted by Duke’s Department of Psychology & Neuroscience shows that how people use their hands while speaking reflects cultural norms connected to racial identity.

The research shows that Black and white Americans tend to gesture differently, and these differences affect how communication is perceived, particularly in interracial settings.

“Black and white people gesture and talk differently, and that’s okay,” says lead author and postdoctoral associate Esha Naidu. “But it can make it harder to connect across group lines. If we take a moment to consider why someone may be communicating differently, that increased awareness could lead to better understanding.” 

Across four studies, Naidu and co-author Sarah Gaither explored how people gesture and how those gestures are understood. In one experiment, participants watched videos of speakers who either gestured often or kept their hands still. Viewers generally rated speakers more positively and as more competent when their gesturing aligned with cultural expectations. 

High levels of movement felt natural to Black viewers, especially when the speaker was Black, while white viewers were more likely to see restrained gesturing as typical of white speakers.

The team also examined real-world conversations by analyzing interviews on the popular television talk show with Tavis Smiley. There, Smiley used more expressive gestures when speaking with Black guests than with white guests, indicating that people subconsciously change their communication styles based on who they are talking to.

In lab settings, the pattern held: Black speakers gestured more often and used larger movements than white speakers. These differences weren’t presented as better or worse, just different.

The researchers said that recognizing gestures carry cultural meaning can help people communicate more thoughtfully and create stronger connections despite differences.
