Humans cannot understand probabilities and real data and instead rely on their own brain and experience.  Note the recent suggestions that mass shooters are overwhelmingly white and that these shooters should be caught ahead of time because they so clearly fit the description.  This kind of post hoc and non-data driven crap reinforces itself and becomes doctrine.  This is the definition of Fake News.  Also, what is the half-life of memory for mass-shootings?  3 months?  #WaukashaParadeShooting
