Humans are not programmable in any meaningful sense of the word. 'Programming' implies direct top-down control of the 'program,' and while humans can be persuaded and influenced, that's not the same as being programmed - programming implies a much higher level of determinism. If humans were programmable, they would always respond to a stimuli in exactly the way they were programmed to by their programmer, which is obviously not the case for anyone.
Rather, humans are learning beings. They don't respond to stimuli in a predetermined way, but are equipped with tools to respond to novel stimuli, or respond to old stimuli in novel ways.
