From the Thumb, a scary little post pointing us to a Newsweek article titled, The Ghosts We Think We See: Normal brain functions, such as seeing patterns, make us more likely to believe in the supernatural. From the article,
Chief among those normal processes is our neurons' habit of filling in the blanks. The brain takes messy, incomplete input and turns it into a meaningful, complete picture.
The mind also tends to impute consciousness to inanimate objects (ever yell at a balky computer?). This leads us to believe that natural phenomena are "purposeful, caused by agents with sentient minds," says Hood, whose book "The Supernatural Sense" is due next year. It's only a short step to thinking that " 'things that go bump in the night' are the result of some spirit or agent," not branches brushing against your drainpipe.
Of course, the Thumb immediately attacks the ID angle, but they make this interesting point:
An important point made in the article is that the tendency to see patters that aren't there or to impart consciousness to things that aren't conscious is a normal outcome of the way the human brain functions, due in large part to having to deal with incomplete sensory input. A couple of important lesson to draw from this (to me anyway) is that, first of all, rigorous empirical testing is necessary in science precisely because everyday perception can be so badly misleading. And secondly, the brain's wiring can make it very difficult for people to disabuse themselves of supernatural beliefs...
Okay. So our Halloween point to be made is that the wiring of the human brain can lead us to see things that aren't there (so they say). In other words, the wiring of the human brain is giving us faulty (on their account) information. Yet, how have we become aware of the fact that the wiring of the human brain gives us false information? By virtue of that same wiring of the human brain, that's how.
So, if our wiring is faulty, why should we believe anything it tells us?
