Behind the Curve documents the resurgence of believers of a flat Earth, as made popular through YouTube videos. The film is a personal exploration of how people became exposed to flat Earth theories (the YouTube algorithm), and how those ideas were reinforced in an echo chamber of social media, rejecting empirical evidence, at a time of increasing countercultural distrust in authority figures and the epistemology of science. The narrative at the core of the film reveals how the screen bubble can envelop a person’s informational exposure, and change their relationships and perceptions in the real world, where confirmation bias is reinforced, making alternative views threatening, and individualism sacrosanct. Information that is contrary to a deeply held belief then becomes increasingly impossible to accept, especially if it has changed your life and circle of friends. So with empathy and a playful warmth, Behind the Curve becomes a warning light to the importance of honest discourse and critical analysis, falsifiability and dogma, but above all, to empathy and understanding of a person’s desire to create meaning and acceptance in a lonely, fragmented culture.
