Why is it that we can tell someone "I'm totally fine!" and they instantly know we're not? Gestures, facial expressions, tone of voice, and other subtle nonverbal cues play a huge role in how we connect with one another.

In this episode, host Charles Duhigg explores how we communicate without words, including a deep dive into the visual and tonal cues embedded in one of the biggest sitcoms of all time, The Big Bang Theory.

He talks with Dr. Dustin York, a professor at Maryville University who studies nonverbal communication and worked in public relations for Barack Obama's 2008 presidential campaign. He also sits down with Dave Goetsch, a co-executive producer and longtime writer for The Big Bang Theory, and journalist Jessica Radloff, who wrote an exhaustive book about the show.

This Slate miniseries dives into the art and science of meaningful conversations, inspired by Duhigg's bestselling book, Supercommunicators.

Supercommunicators was produced by Sophie Summergrad and Derek John, who also did the sound design. Our technical director is Merritt Jacob and our supervising producer is Joel Meyer.
