Culture War Roundup for the week of July 14, 2025

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.

I mean, this is basically just saying "sometimes lying results in people believing the truth".

No. It says that lies can increase utils. Truth and utility are independent concepts, why do you have it confused?

More generally, you say "I am not sure why rationalists cannot understand this argument". Notice that if you're not sure why somebody doesn't accept something, one of the possible answers is in fact "they understand it just fine, but there's a counterargument that they understand and you don't".

Then demonstrate it. The very first sentence of your reply shows that I was right.

why do you have it confused?

I don't.

You said "calculate utility correctly". To calculate utility correctly requires knowing the truth. Different worldstates result in different expected utilities for the same course of action, so a utilitarian with a bad understanding of reality will act suboptimally according to his own utility metric - often wildly so. The obvious example is that genocide looks utile if you think the relevant demographic are all evil.

Hence, "lies can cause people to calculate utility correctly" = "sometimes lying results in people believing the truth".

This is distinct from "lies can be utile", which is broader and covers things like people having different utility metrics and/or people not actually being utilitarians and/or direct, non-choice-based belief effects (e.g. stress). That condition of "if you need there to be lots of utilitarians" is actually relevant to my point, y'know.

So we are back to square one. It seems to me that you are truthitarian and not a utilitarian, which is fair game. Let's investigate it on my previous example of Kant's axe murderer asking for you wife. Since she can be destroyed by [you telling] the truth about her whereabouts, then she should be destroyed, right? Because telling a lie can hamper yours and murderer's ability to correctly calculate the utility in the future with immense impacts. Or you should tell a lie, because death of you wife would be more negative utility compared to whatever impact on correct calculation of utility is there from telling a lie. What is your answer to the axe murderer? Is the truth the ultimate value that should destroy all and everything in its path? Or is it subordinate to other values such as your best estimation of utility in a given moment?

This is distinct from "lies can be utile", which is broader and covers things like people having different utility metrics and/or people not actually being utilitarians and/or direct, non-choice-based belief effects (e.g. stress). That condition of "if you need there to be lots of utilitarians" is actually relevant to my point, y'know.

That is why amended Sagan's mantra:

That which can be destroyed by the truth should be - except if it clashes with some other higher value (e.g. causing negative utility), in that case you should not destroy that thing by the truth.
