This sounds very much like a psychological exploration of human behaviour. Could we get some more context? - is this for a school project?
I would challenge you to actually go out and talk to friends/family, or even others about this. So come up with a few questions, that you can then use to direct your conversation.
An example being: Have you ever done a video challenge, such as the cinnamon challenge? What made you want to take part? What would it take for someone to convince you to do a video challenge? etc.
This is going to very much go into motivations socially, personally etc. I do not know any research off the top of my head, but I would try searching in google scholar, and you may be surprised what you find.
