Abstracting out the essence of this article: It&#x27;s arguing about the danger of ubiquitous &quot;big data&quot; in certain contexts.<p>The human population around 8 billion, which is 2^33. 33 is roughly the number of pairs out of 9 objects. Heuristically, this would mean that if we test for more than 9 boolean variables (high&#x2F;low), purely by randomness we will start seeing correlations due to a &quot;limited&quot; population size of 8 billion. If we start treating people just based on those observations, we would seriously wreck human health.<p>Diagnosis (decision making) based on correlations (rather than causality) is very tricky.
