“We see, and therefore usually get, what we expect.” – John Locke.
Experts say that we have approximately 2 million bits of information per second bombarding us at any given time. It is estimated that we can only process 178 bits per second. To deal with this your brain generalizes and/or purposely ignores 99.99% of available information. This leaves a huge gap between the information that is available to us and the information we notice. The information that we notice is the information that supports what we expect; therefore, we see what we expect to see. Since we see what we expect and the most obvious path to follow is the one we see, we follow it. And when we do, we get whatever is at the end of that path. So be careful what you expect because that is what you are most likely to get!
