From Brian Horton
Dan Jones reports that people who are told voting patterns can be predicted by measuring brain activity still believe the subject’s decisions are based in free will (27 September, p 11).
We could get the same result without the fancy technology by giving someone a thorough personality test that will also predict their decisions with very high accuracy. That is because our “free will” decisions now are based on our past experience.
So I can quite happily believe I am making decisions based on free will, even though my wife can predict those decisions with 100 per cent accuracy based on over 40 years of observation.
