How often do our brains make connections that don’t exist?  More often than we think.

A happened and then B happened so A caused B.  Really?  Hmmm…

Correlation (no matter how weak/strong) and causation are two incredibly different things.  Confusing the two often leads to poor decision making and erroneous conclusions.

Sometimes the outcome is trivial.  Two similar back-to-back songs when a music player is set to random?  Easy enough fix.  To paraphrase Steve Jobs:  “We’re making it less random to make it feel more random.”

The concern is when our cognitive bias leads us to make poor financial decisions.  The consequences can have serious, long-term effects.

As unsatisfying as it may be we need to accept that random is just that – random.
