Heuristics that almost always work
I read them as sloppy caricatures that provide little value to the conversation.<p>Let&#x27;s take the security guard: &quot;The only problem is: he now provides literally no value. He’s excluded by fiat the possibility of ever being useful in any way. He could be losslessly replaced by a rock with the words “THERE ARE NO ROBBERS” on it.&quot;<p>That is blatantly not true, the guard provide value since the wanna-be robbers don&#x27;t know whether the guard will be of any value, and a rock could not provide any deterrent. Losslessly?<p>The doctor (if there is someone skeptical of doctors it is me, if I were less lazy I would have greatly enjoyed fighting to make some useless US dermatologists lose their license): &quot;Her heuristic is right 99.9% of the time, but she provides literally no value. There is no point to her existence. She could be profitably replaced with a rock saying “IT’S NOTHING, TAKE TWO ASPIRIN AND WAIT FOR IT TO GO AWAY”.<p>This is an unhelpful caricature, too, because if we add &quot;and call back if it does not&quot;, it looks like a very reasonable approach.<p>Un-nuanced and quite sloppy presentation of heuristics.
