This is an interesting opinion piece that highlights how documentaries can distort our view of reality, and specifically how omission of facts can deceive. But it isn’t just documentaries that do this. More broadly speaking, whenever the public is given “facts” about anything, there is always a lens through which the information is presented. So long as it is filtered by something, someone, somewhere—what is provided, and what is not, skews the way we think about the thing. The reality will never be fully known, or complete. Conclusions are made, making the best with the presented information, but the point is we should question our own interpretations, those of others, and keep an eye out for the dog that didn’t bark.
