This weekly roundup thread is intended for all culture war posts. 'Culture war' is vaguely defined, but it basically means controversial issues that fall along set tribal lines. Arguments over culture war issues generate a lot of heat and little light, and few deeply entrenched people ever change their minds. This thread is for voicing opinions and analyzing the state of the discussion while trying to optimize for light over heat.
Optimistically, we think that engaging with people you disagree with is worth your time, and so is being nice! Pessimistically, there are many dynamics that can lead discussions on Culture War topics to become unproductive. There's a human tendency to divide along tribal lines, praising your ingroup and vilifying your outgroup - and if you think you find it easy to criticize your ingroup, then it may be that your outgroup is not who you think it is. Extremists with opposing positions can feed off each other, highlighting each other's worst points to justify their own angry rhetoric, which becomes in turn a new example of bad behavior for the other side to highlight.
We would like to avoid these negative dynamics. Accordingly, we ask that you do not use this thread for waging the Culture War. Examples of waging the Culture War:
-
Shaming.
-
Attempting to 'build consensus' or enforce ideological conformity.
-
Making sweeping generalizations to vilify a group you dislike.
-
Recruiting for a cause.
-
Posting links that could be summarized as 'Boo outgroup!' Basically, if your content is 'Can you believe what Those People did this week?' then you should either refrain from posting, or do some very patient work to contextualize and/or steel-man the relevant viewpoint.
In general, you should argue to understand, not to win. This thread is not territory to be claimed by one group or another; indeed, the aim is to have many different viewpoints represented here. Thus, we also ask that you follow some guidelines:
-
Speak plainly. Avoid sarcasm and mockery. When disagreeing with someone, state your objections explicitly.
-
Be as precise and charitable as you can. Don't paraphrase unflatteringly.
-
Don't imply that someone said something they did not say, even if you think it follows from what they said.
-
Write like everyone is reading and you want them to be included in the discussion.
On an ad hoc basis, the mods will try to compile a list of the best posts/comments from the previous week, posted in Quality Contribution threads and archived at /r/TheThread. You may nominate a comment for this list by clicking on 'report' at the bottom of the post and typing 'Actually a quality contribution' as the report reason.

Notes -
80+ dead and rising in Central Texas floods.
Kerr County is the Summer Camp capital of Texas. It's rugged hill country terrain and proximity to the Guadelupe River is perfect for exotic adventures outdoors, and it is close enough to major population centers to be convenient for parents to drop-off their children.
The downside is that low-lying cabins get completely wiped out in flood events. Camp Mystic for girls has double-digit casualties alone.
It is a common refrain to bemoan the fact that, "we don't let kids be kids anymore," and that may be true, but a big part of it is that we as a society simply don't consider the inherent risks acceptable anymore. I shudder to think about making 10-year-olds sit through a 30-minute site-specific emergency preparedness seminar, but that's where this is going, and given what's happened, I'm not entirely sure it would be a bad thing.
I hesitate to be the cold calculating math guy but.... no wait, I can't help myself, I am that guy: 80 people isn't actually that many. I mean, obviously every death is a tragedy for themselves and the people who knew them. But when you zoom out to the perspective of a country of 300 million people, it's tiny.
80 deaths * 80 QALYS lost * 365 * 24 * 60 = 11 QALMS (Quality adjusted life minutes). That is, on average preventing a catastrophe of this magnitude is worth 11 minutes of life averaged over everybody in the country. If your proposed solutions of "don't let kids be kids anymore", "take time doing flood preparedness drills" and "spend lots of money damming every river everywhere" costs more than 11 minutes per person in terms of actual time and lessened enjoyment and life lived, then it won't be worth it. (though if you can get costs lower than that it is worth it).
Google says annual flood deaths in the U.S. are ~125, so ballpark this number is approximately right, you'd have to prevent this many deaths at that cost ratio consistently every year (and you'd actually have to reduce it by that much, across the entire country, not just Summer Camps).
I think we should let kids be kids, and we should sometimes consider the inherent risks acceptable. People die, it's a thing that happens. And it's bad that it happens, but if we don't have magic finger snapping powers that make it not happen for free, then we have to consider the costs and tradeoffs. And the thing nobody wants to admit is that, mathematically, there MUST be a point where the costs are no longer worth it. You can make arguments about where that point is, but the argument has to start with the assumption that there is such a point.
People would rather spend time attending a safety seminar or working than reduce their lifespan and spend an equal amount of time being dead, so you can't trade off QALYs for time worked 1 for 1. Instead it's just another adjustor to quality-of-life, roughly equivalent to time spent working without being paid (the actual workers get paid, but it destroys the value they would produce doing something else). You could also compare the cost to the standard "economic value of the life" calculations derived from the premiums on risky jobs, and indeed certain safety measures require risky construction work and thus are partially paid for with the deaths and disabling of the construction workers you have implement them. Your calculation is still useful as a sanity check though, even though the actual tradeoff in time spent wouldn't be 11 minutes.
I'll trade safety seminars 1:1 for shortened lifespan any day of the week.
Note that "total blindness", "clinical depression", and "chronic pain" all involve average QALY estimates that still imply an above-zero value of life. There's a lot of people with those conditions who would gladly sign up for boring seminars if they eliminated their condition for the duration of the seminar. And of course history is full of people opting for unpleasant slave-labor over death. So if you're not joking your opinion seems non-representative.
Note my trade is not at par for QALYs, it's at par for unadjusted LYs.
Oh sure, but in this case we're trading off with risk of being killed as a child, not 11 extra minutes on your deathbed, so QALYs are the appropriate metric. By "reduce their lifespan" I was imagining it as taking those minutes from their prime, reducing healthspan by an equal amount.
