The fact is, with either approach, people tend to predict the movement of the market many times up until now so the chances of them hitting the correct one are high. But if I were to choose, I'd say the analytical approach is better for me rather than a clairvoyant approach because the analytical approach has a basis on their predictions compared to a clairvoyant one.
I agree with you on the first point you make, very true. You can see I got psychic info both side...which is reassuring to me concerning your point.
I do not understand your last point about analytical has a basis and not the clairvoyant approach, for 2 reasons :
1- any analytical approach has to be tested over large number of data to get validated ( and people in general underestimate what is large number...) so it is the same thing with clairvoyant approach ( you can not appreciate the validity based on 10 or 20 predictions... that means nothing one way or the other....)
2- Artificial intelligence is the same for me than clairvoyance, in the sense that in both case your analytical mind is unable to understand the result. Using AI means to get at the end a "magical formula" you can not understand, but that is the beauty of it... you are researching in a much larger universe the solution, beyond the small human understanding.... the same for clairvoyance. In both case you still have to really test it with large number of events to defy randomness, to acknowledge you are on something.
So why limiting yourself only to tools you do understand ? why not expanding to a larger universe of what you do not understand but can test truly ?
