No actually it does not.
It's all psychological. You have to believe it works, even at the subconscious level.

Had absolutely no impact on me. And the quality of the youtube vid was excellent.

Similarly with lucid dreaming, I've effortlessly achieved things first time that many struggle with. The only limitation I found was with light switches not working, even when I didn't believe it in the slightest (though I did immediately disprove the idea that light levels can't be changed by 'thinking' the light on instead). Very few things seem to be limited by the brain's software. Many things are limited by expectations.

A lot of Derren's other illusions work on a similar principle. There's one where he manages to manipulate how people spin a set of tables, and convinces them they're not moving the table but following it. Obviously they are moving the table, they're just not aware of it.

Also have to bear in mind that some people are simply 'weak-minded', and easily influenced.
