This type CAT was invented as a joke, and winds up being one of the favorite excuses some viewers have for failing a session. Basically, a viewer says, "It wasn't that I was wrong - I was just picking up on what somebody else (the tasker, the monitor, another viewer, etc.) was thinking about the target. They were the ones who were wrong. Mental telepathy, you know."
Sadly, research and data keeping have shown that such a CAT actually does exist. However, it is not as common as a viewer would like to have it.
