Mike Mullane - Normalisation of deviance - IAFF - Part 1

Thanks for posting these, I'd only seen Normalisation of Deviance mentioned in these two youtube videos by Mike Mullane and never thought to look any further: ▶ this video [link] and the uploader references some further links: [link] [link] and references this book (about the Challenger Disaster): [link] which has an overview here: [link] including these two excerpts I found interesting in this context: "Chapter nine she explains how conformity to the rules, and the work culture, led to the disaster, and not the violation of any rules, as thought by many of the investigators. She concludes her book with a chapter on lessons learned." "She mainly emphasizes on the long-term impact of institutionalization of the political pressure and economic factors, that results in a “culture of production”."

> If you just use them all the time, you don't have to remember to use them in the right situation. I know of dead cave divers who followed protocols only when they really needed to and then one day made a category error and didn't follow the protocol when they really needed to. I've gotten crap for following through the motions of protocols when they I "didn't need to" but if you do it all the time then you never make those kinds of category errors. There's no downside to always following protocols, there's high downside for making category errors that you wouldn't make if you just always followed protocols. Similarly you should always use your parking brake, even if you are on flat ground so that you never make a category error there (or just get hit by someone when you're on flat ground and have a rollaway). Similarly, signal your intentions every single time. You're doing it for the pedestrian you didn't see, or even just some idiot flying up the shoulder of the highway who shouldn't be there, but signal your intentions to take the exit so you move predictably.

> In fact the "hick" position is the scientific one. If someone eats unrefrigerated pizza ten times without any Adverse Events, then in fact that's an experiment providing (admittedly crude) scientific data I'm going to strenuously disagree with this one. "I've done it 10 times and it has been fine for me" is the logic behind the normalization of deviance and the Shuttle disasters and (in my world) cave diving fatalities: ▶ this video As a cave diver I also see this leading to fatalities where divers cut corners on the rules of cave diving, see no immediate consequences and continue to do so up until they wind up dead some day (there are often very binary outcomes for breaking the rules in cave diving). The author of this article does provide a fairly compelling science-based _hypothesis_ though as to why eating-8-hour-cold-pizza is safe though that goes beyond his personal experience. He does argue that the N is actually very large due to reasonable assumption that many college students do this and there is no evidence of a plague of college students in ERs. He also argues that pizza specifically should be pretty safe after 8 hours due to most of it being composed of things with longer shelf lives and tomato sauce having a low pH. That is still mostly all the kinds of rationalization that NASA did though. So those should be at least somewhat scientifically tested. A simple survey of college students could determine their practices of how often they ate morning-after pizza that ha
