Silly me, I forgot that my life is nuts and I'm bad at this sort of thing. But what can you do?

I feel like my Psychology class is slowly dismantling all hopes that I had for human objectivity. First it was hindsight bias and false memories, now we're starting in on the way we perceive the world. Reliable? Mostly. Accurate? Maybe. But then again, there's change blindness, when a man who asks a stranger for directions can be switched with an Asian woman and the direction-giver may not notice. Admittedly, this is because all of our senses are picking up an amazing amount of information at any given time, and we can only consciously focus on a very small fraction of it (think a ratio of 1:2,750,000). Thus, our senses are keen enough to get us by through most of everyday life, but the holes that scientists have uncovered–in the form of various optical and auditory illusions–worry me because as we build an increasingly complex society, there will be an increasing burden on our senses. There may be a time when our basic senses become inadequate for everyday life, and what then? Just something to think about.
