First read this article by Michael Shermer, about the human propensity to hear meaning in all sorts of meaningless noise. We are good at finding patterns; but not so good at detecting when we have superimposed a pattern on something meaningless. In Shermer’s words:
Unfortunately, we did not evolve a Baloney Detection Network in the brain to distinguish between true and false patterns. We have no error-detection governor to modulate the pattern-recognition engine. (Thus the need for science with its self-correcting mechanisms of replication and peer review.) But such erroneous cognition is not likely to remove us from the gene pool and would therefore not have been selected against by evolution.
Then have a look at this YouTube featuring “Stairway to Heaven.” It’s played first forward, with lyrics, then BACKWARD, with lyrics. Does this prove the satanic genius of Led Zeppelin? Or simply our lack of a Baloney Detection Network?
