delightful exercises....................

Since Donald Trump’s surprise victory -- though it wasn’t a surprise to those of you with the power of hindsight -- there have been numerous after-the-fact explanations for why Trump beat Hillary Clinton. Many appear to be delightful exercises in data mining, the finding of “historical patterns that are driven by random, not real, relationships.” Add to this the assumption that these explanations are durable and will repeat in the future, and you have the makings of a terrible investment process.
