Have you ever wondered what exactly it is that makes us human? Discovery Channel invites you to find out in the new interactive series Head Games where both viewers and on-screen subjects are challenged with brain games, mind puzzles and social experiments. Narrated by John Krasinski, the show delves into the inner workings of the deeply complex human brain. Through the design and execution of social experiments you will see how everyday people on the streets perceive, conform, and make moral choices when in real-life situations … and what the brain is actually doing to dictate behavior or react to uncomfortable, and, at times, confrontational, circumstances.
