Five

Five (YouTube) — a polygraph examiner and lie detector hired for creators & digital. Rio Ferdinand and Joel Beya's channel.

Channels built around a presenter need the polygraph to serve the host, not upstage them. The examiner supports the conversation and stays out of it otherwise.

That is a different job from a broadcast format, where the examiner often delivers the result directly. Here the read is handed to the host and the host carries the moment.
