They assume that everyone knows exactly what it means,
Most importantly, themselves.
and if you ask for a definition, that seems like trolling.
Yes. If you suggest they're conceptually muddled, instead of attempting to demonstrate their conceptual clarity, which should be trivial to do if they have it, they will get huffy and declare you a troll.
That too, actually. Perhaps the word is usually used to mean a set of this all. You know, the wider the meaning, the greater the chance that at least some part of it can be defended successfully in a debate.
That's the true Dark Art. Endlessly equivocate on the meaning of your terms. It's so dark, you can manipulate yourself into believing that you know what you're talking about. See Rand and "life" for details.
Diana Hsieh interviews Dr. Doug McGuff about avoidable injuries and deaths.
He's an emergency room physician in South Carolina, so he's pretty much just talking about what he's seen-- different regions have different characteristic injuries.
He says that you're safest in the largest car you can afford, which raises some interesting ethical issues.
There's a fair amount about the risks of getting overfocused on getting something done. This adds tremendously to the hazards of using ladders.
Also, did you know trees can go sproing? One of hazards of chainsaws is that a good bit of energy might be stored in a twisted tree trunk. Don't just know your physics, apply it!
More generally, there are machines and situations (ATVs, chainsaws, airplanes, skiing, etc.) which tend to make people feel more competent than they are.
On the other hand, injuries from rock climbing and horseback riding are less common than you might think. I don't know why the ancestral environment didn't give people a reflexive distaste against diving into water. Perhaps people back then had too much sense to dive much.
One of the pieces of advice-- to get out of stressful relationships-- is too general. This is mostly a good idea, but from what I've read, leaving a violent relationship can lead to more risk of violence. It's still a good idea to leave, but it's important to leave cautiously.
Both McGuff and Hsieh are objectivists, so some of the discussion might be in mind-killer territory.
Edited to add: It's possible that objectivism would be better discussed under a new post. It's certain that there's a bunch of interesting material in the podcast, and avoidable accidents are worth discussing.
