Do you have your camera on during meetings?

Weird question, but I am contemplating a research study... Do you have your camera on during meetings? In my organization, it is a given that yes, you will turn on your camera. And, I hate it.

My partner is in the sciences and he NEVER uses his camera. I am jealous. And kind of trying to figure out what the norm is, or if this even a topic I want to do research on.

Thanks in advance!
