Culture War Roundup for the week of March 31, 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.

My notes are disorganized, spread out over my app and screenshots, so I’ll give you topics to plug into google scholar. When you learn something, that information goes through a reconsolidation window <8 hours, which is the memory cementing into your brain. Now, when you remember something (from the cues that point to the old memory), the old memory is “reactivated” and then shortly afterward re-enters the “reconsolidation” window. During this window, an old memory can be updated and changed, including its emotional aspects, but only if it goes through reactivation before the attempted manipulation.

  • memory reactivation reconsolidation craving / addiction [for its use in drug addiction and alcoholism, which can be extended outside its scope because addiction can be construed as a really strong desire or a thing just having very high positive valence]

  • memory reconsolidation music / affect [one study found that, after reactivating a memory, if you remember it with music then the memory takes on the vibe of whatever music you listen to. In other words, when you remember things under the influence of music, your memories may become more like the music emotionally]

  • Tetris effect PTSD [car accident patients at a hospital, when brought in during the reconsolidation phase of the memory, if you have them play Tetris their rate of PTSD decreases; similarly, if you have people reactivate a car accident memory and then play Tetris right after, their rate of negative flashbacks decrease]

  • eyewitness misinformation effect test reconsolidation [if you have eyewitnesses take a test where they relay everything they saw, and then you introduce “misinformation” afterward eg by an interviewer just telling them false information, then they are likely to revise their true information into false information. This is stronger than if they didn’t take the test. The act of taking a test actually increases the amount of misinformation grafted and updated into the old, true information]

  • reactivation reconsolidation fear / phobia [the new paradigm of treating phobias is that reactivation must occur for the memory to have longterm change through exposure. For instance, if you’re afraid of mice, you would briefly recall past fearful memories for 8 minutes, wait a few minutes, then “exposure” yourself to the mice. This updates previous memories, whereas an exposure session without the memory reactivation has less longterm extinction (or none at all)]

  • a recent study trending online, “improving mental health by training the suppression of unwanted thoughts”. https://x.com/AdamMGrant/status/1888968823929471032 . In this study, the Cue of an unwanted thought is focused on for a couple minutes, and then a person “trains” himself to ignore any thoughts that come afterward. This is reactivating (focusing on cue intensely), and then updating the old memory through reconsolidation manipulation (focusing on quieting the mind).

  • There’s a case I read of a child who saw a snake at a park and had no emotional reaction, but injured her hand on a car door an hour afterward. She became phobic of snakes. This is because the memory of the snake was meshed with the injury during the snake’s reconsolidation window, amplified by the evolutionary “potency” of snakes which make them particularly sensitive to this phenomenon (speculated).

  • Alcohol after learning can help retain information, and thus is speculated to occur because it blocks out the learning of “new” information which can cause interference with the pre-alcohol information; in other words, the pre-alcohol reconsolidation is protected against any post-alcohol memory interference because we learn less when drunk.

  • Perhaps one more tangential topic: giving yourself a test is often better for learning than reading / elaborating, but when you know very little of the material, it’s actually worse because you could “train” yourself to provide the wrong answer when seeing the cue. When studying, if you don’t know the answer, it’s better to not answer the question than guess, it would seem
