IRVA 2010 – Consciousness and the Interface Theory of Perception
It is generally assumed that truer perceptions are fitter perceptions, and thus that natural selection has shaped our perceptions to be good estimates of objective reality. I argue that this assumption is false. Instead, simulations based on evolutionary game theory indicate that our perceptions constitute a species-specific user interface that guides behavior in a niche. Just as the icons of a PC’s interface hide the complexity of the computer, so our perceptions usefully hide the complexity of the world, and guide adaptive behavior. Our perceptions are tuned to utility, not to objective reality. I discuss the implications of this result for theories of consciousness and the mind-body problem.
