Sidenote:
IQ is an interesting and extremely useful predictor [GASP] of many things. But it's difficult for a person with a significantly higher IQ to grasp just how much different the world is to someone in the <90 set.
Best book that illustrates this was called "McNamara's Folly: The Use of Low-IQ Troops in the Vietnam War". LBJ/McNamara needed meat for the Vietnam grinder and waived IQ minimums in spite of the Army's protests. The results (and the high casualty rates) were predictable.
It's a good case study of a litany of things we do on a daily basis that a huge subset of the general population either can't do, can't understand, or do poorly.
Unsurprisingly, low IQ people are much easier to fool. They might not eat dog waste (which, I might add, Phins never wrote), but they'll take as reasonable instructions all kinds of thing your average commercial pilot* would question.
*(Commercial pilots average around 120 IQ, which seems a bit high to me based on narrow personal experience and having had exposure to some truly bright people outside the field. Military pilots probably a bit higher, but I doubt by much. )
