Are our trading decisions impacted by subliminal messages?

I have been a fan of Derren Brown for a number of years now. His skill of ‘playing’ with the human mind and the subconscious are just fascinating to me.

This clip about subliminal advertising and how he is able to manipulate those guy’s thinking patterns makes me wonder in how far traders are at the effect of subliminal messages which subconsciously impact trading decisions?
