In my opinion this is the best magician one that has been posted here. Atleast Eric Mead talks about something relevant to the audience. He is demonstrating the correlation between what is real and the placebo effect, whilst talking to medical stuff.
Where as Lennart Greens is about shortcuts and patterns and Keith Barry's is just about look at what I can do. Meed did something amazing here he was essentially talking to people in the medical field and used things that were relevant to them. He may or may not made up the article that he read but I can assure you that everyone there would believe it. Why? because it seemed plausable and it goes back to the old saying, the more you know the understand. Everyone there I am assuming knows a lot about medicine but their own ignorance would attest that they do not know everything and what he was saying sounded plausable.
im always a fan of TED talks
