The article criticises the unquestioning use of bad heuristics. One needs to think very carefully about how accurate the heuristics employed are at describing the unseen (but directly desired) attribute(s) as well as what un-desirable attributes it may be silently signalling. As someone who worked at an investment bank, I'd go ballistic when managers would turn away candidates because their resumes weren't properly aligned or formatted. The irony was amplified by the fact that we were not a client-facing trading desk. Here the heuristic used (resume formatting) did not correlate with the desired attribute ([trading skills]) but did correlate well with some undesirable attributes (insecure children more concerned with form than function). |

What I was trying to claim is that there’s a relationship between heuristics and the ham/spam ratio of the documents being classified. When there is very little ham and a lot of spam, my claim is that false negatives are extremely expensive. When the benefit of hiring is very high and the cost of interviewing is low, my claim is that false positives are relatively cheap.
Given these two, my claim is that given current market realities, when hiring programmers for a mission-critical role the best strategy is to go light on spam-filtering heuristics and heavy on direct inspection of the ham content.
But obviously, some heuristics have their place. To a certain extent, everything except “Start work on Monday, there will be three month’s probation” is a heuristic.
And “This article is almost complete useless” is also true, given that it says in many paragraphs using a contrived format what I just said in two paragraphs, it obviously contains a lot of redundancy and extraneous noise!
