Culture War Roundup for the week of October 3, 2022

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.

The easy exercise is to try and solve exam questions from n years ago. Most of the time, in most subjects, people just walk away shocked how much harder they were.

I don't know about your course in particular, but the "look how badly current students fail old exams" technique is deeply flawed. When a course is changed it almost always adds some parts while removing others.

If the previous version covered points ABCD but the new course is now ADEF then it's only natural that today's students would be confused by points B and C. It's not a fair comparison unless you also consider how well the original group would have done on E and F.

Right, that's fair, but it has been long enough since I took those courses for me that I can also look at present ones (including ones that I didn't teach or practice in the meantime) and convince myself that I find them easier than the ones I took 10-15 years ago.

There might be some sources of error in that comparison. Hopefully 10-15 years of practical experience makes many of the types of questions you'd see simpler to solve. It's like trying to remember the mental/emotional state of not understanding the solution to a puzzle that seems obvious/straightforward in hindsight. I'd still agree things are probably simpler. In my own academic career I had the misfortune to having to take two versions of a foundational course; the first time as a non-program student taking it as a prereq to continue taking interesting higher level courses as electives, the second time several years later as a program student to meet degree requirements. The first was a notorious weed-out course, while the second one was significantly less difficult although more practically applicable for modern software.
