Given the various research suggesting that our back brains make decisions before "we" know about them (admittedly rather nicely challenged by Daniel Dennett in Freedom Evolves), here's to suggest that the only real influence we have on decisions is the processed information we feed into that back brain.

In other words, we formulate a problem, feed it back, and ask, "how do I feel about this?" Back comes the decision, with no take-it-or-leave-it options. It's a done deal.
