Why Do People Believe That Crap Derren Brown Said About How He “predicted” The Lottery?

He used the split screen, the “shake” was added, it’s a digital effect.. the view from the back of the hall was prerecorded, if he wanted to predict the numbers he could have done BEFORE the draw, but his little excuse was “because we can’t announce the numbers before the draw”.. which is wrong because a prediction is not the same..
Just another scam, like David Blaine hovering, tv work. I like Derren’s other work though, the REAL stuff.
