Videos seem like such compelling evidence. And again, like many other sorts of visuals, but perhaps, especially for videos. When people see video, they think they've gotten the story. They think they understand what's going on. What people don't tend to realize is both the extent to which their own prior attitudes, their own biases shape what they literally see in the video, as well as what they construe from it. And they also don't appreciate how all of the formal aspects of the video, the size, the framing, the point of view, the angle, the sound, if there's any also shape what they are taking from the video.
