 Four Austrian scientists published a paper in the journal scientific reports called video conference fatigue from a neurophysiological perspective based on EEG and ECG. So scan in the brain, scan in the heart. And they found that those who watched the video conference showed signs of fatigue, that there was evidence that their brain had to work harder than the people who were there in person. My personal theory, Shannon, is that the fact that you know everyone can see you, you know, that's why a lot of people turn their camera off. But even then the feeling that there's a camera I am definitely seen is different in a video conference than it is when you're sitting in a conference room and you know everybody's eyes are pointed towards the speaker, right? So you don't feel the pressure on you the way you do in a video conference where you're like, well, everybody could be looking at me. I don't know who is, but everybody could be.
