I'm sure a lot of you have read in popular science magazines about Libet's experiment ( en.wikipedia.org/wiki/Benjamin_Libet ) and the supposed implication regarding conscious will of acts.
From the wiki.
" Libet's experiments suggest unconscious processes in the brain are the true initiator of volitional acts, therefore, little room remains for the operations of free will. If the brain has already taken steps to initiate an action before we are aware of any desire to perform it, the causal role of consciousness in volition is all but eliminated. "
A simple solution to this problem of a acts being initiated in advance is that the brain does a prediction of where the concious will ( resulting will ) is going to land on the time the act is ready to execute. One way of predicting the resulting will is if it is derived from a lot of competing wills in the brain and there is a voting system. Then as in almost any election the winner can be predicted long before all the votes has been counted. With the predictor you don't only resolve the problem of initiation of acts you also have a concious control. If there is no prediction of the concious will the system would be very inefficient because of the veto anyway.
