Review of Behind the Curve (2018)
Seen in 2019.
Flat Earthers as a psychological phenomenon, mainly in their own words.
Surprisingly lucid as a piece of pro-scientific skepticism. The believers in a flat Earth are absolutely wrong and the filmmakers do not attempt to muddy the waters in that regard, but they are admirably careful to humanize the believers and dispel the complacent notion that they are simply idiots. Indeed, for a single documentary on the personalities espousing a single pseudo-scientific issue, Behind the Curve gives a good general picture of the relevant cognitive biases, a cogent summary of the Dunning-Kruger effect etc., and it’s also fun to watch.
