I think what we all just watched was misdirection, It was him planting the suggestion in ours minds that that was how he really did it (with that group of people) and made it seem so real that we don't doubt it. I love the bit at the end where he also plants the idea that he might have actually rigged the lottery!... which you never know.
It really is easy to manipulate people so knowing there was no way of manipulating the machine he just manipulated us in this reveal show, quite clever.
It might be like next week where if he puts the idea in your head to not get up your will power will keep you there because you want to believe it will work.
Having said all this im sure people have had instances in their lives where they have willed something to happen so much that it has actually occured putting some truth in all this I guess which opens the whole debate about a higher being.
