It depends. Need to know the algorithm. If it's just that 90% of people choose one, then it can choose that one and be right 90% of the time without even taking your brain scan into account. Or maybe 90% of males go one way and 90% of females go the other way, well that's an easy thing. Or maybe nobody ever chooses one when it's raining, and there's a 10% chance of rain tomorrow. Or, maybe it does a perfect simulation and knows exactly what you'll choose, but flips it 10% of the time just for fun. Any of those would have different ways of optimizing, so it doesn't make sense to speculate without knowing exactly how it works.
