Edit2: I'm revising the question again. Please note that I am not talking about card tricks like THIS. I'm talking about specific examples below which are at least portrayed as far more complex, ornate, and supposedly based on psychology and suggestion.
Derren Brown (website) is described as being a "a British illusionist, mentalist, painter, writer and sceptic" (WIKI). He pulls off various feats that are, indeed, insanely amazing [looking]. Examples:
- Guiding someone via seemingly nebulous questions to a buried container in the desert
- Convincing someone to want the exact present that Derren has pre-wrapped for them
- Influencing two individuals to make logos and slogans that he predicted ahead of time
- Predicting the path someone would take through a grocery store and what they would buy
Derren's website (as noted by @Oliver_C) states that he "combines magic, suggestion, psychology, misdirection and showmanship in order to seemingly predict and control human behaviour, as well as performing mind-bending feats of mentalism."
I do not consider the above to be in the magic category, and know that some believe he is using NLP to accomplish these feats (LINK), despite his own denial of using such a method.
If one holds that this is "magic," please make a solid case for why it is in such a category other than citing his website or methods, for his stated methods also include psychology and misdirection. I classify the above as those which appear to be using psychology or suggestive wording to influence others and make "predictions" appear real.
Is it possible to influence people's choices so precisely via psychology or linguistic suggestion, as to accomplish what is shown above?
