How do viral videos stimulate our brain? What makes our brain want more? What keeps us scrolling? Why do we smile at our computer screens? Join the conversation with an award-winning Harvard data scientist who analyzed thousands of hours of viral and non-viral videos from major creators (e.g., MrBeast, Dude Perfect) from a neuroscience perspective: brain waves, facial expression, and eye movement. Certain neuroscience signals are present across most viral videos - and largely missing in non-viral videos. This makes "virality" scientific and largely predictable!
