Do we see reality as it is?

Interesting TED talk on our perception of reality. Do we see reality as it is? We discussed this topic in various guises throughout the history of IPS forum, the myth of the given as but one example. One expression of the latter is that we indeed do experience reality as it is via satori or other such 'ultimate' states of consciousness. This talk is more grounded using science and evolutionary theory on how our perceptions are based on 'fitness,' which is far from seeing reality as it is.
