It's not as if intuition can miraculously move an investor's hand independently of the normal causal chain and make him click "buy" rather than "sell". Of course, we will always be surprised by decisions that people make, but that's just because we can't rewind the tape and play it back with exactly the same starting parameters. I believe that the brain follows classical laws, but even if quantum indeterminacy had a role to play, it wouldn't add anything that we don't already have with the pseudorandomness provided by classical chaos.
