Nah, &#x27;paviva is right. Unnecessary tests <i>are</i> a problem, and you can put them in the same bag as hypochondria and WebMD abuse in terms of things where our brain&#x27;s heuristics and cutting corners in evaluating probabilities start to work against us.<p>&gt; <i>compared to the other health issues of society, like overwork, junk food, sedentary life styles etc...</i><p>You can always find bigger issues. But given that there are startups and big companies that try to solve the issues you mentioned with spurious, half-assed, unscientific pseudo-tests (yay &quot;wearables&quot;, yay &quot;Internet of Things&quot;!), it&#x27;s even more worrying, because suddenly testing abuse may get coupled with the problems above.
