Culture War Roundup for the week of September 30, 2024

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 think you're being naive here.

The scale exists, but it doesn't know the difference between a pound of ham and a pound of prosciutto, scan the ham, put the prosciutto on the scale, scan the ham again, put the ham on the scale. And they're not constantly monitoring the tape for minor irregularities in movement.

They’re very precise. Steaks are individually plastic wrapped here, so you’d have to find a ham that weighs exactly 454 grams or whatever. They beep very loudly when there’s any issue. The staff meticulously check your bag if the system flags any issues. I’m sure people still steal stuff, but it’s less easy than the original post assumes.

You clearly live in a much nicer area than me; meticulousness is absolutely not part of standard operating procedure at my local grocery stores.

THey have the technical ability to be very precise, but any modern store is going to have them calibrated to allow some gratuitous shifting.

You need only look at the difference between plastic and reusable bags to see how generous they must be by default. If you put a reusable bag down without an item, they're heavy enough to register as one, so there's a bit of technique to putting your first item down.

My local grocery stores' self-checkout kiosks all have a special "reusable bag" button - you press it, put your bags on the bagging surface, and continue on with grocery scanning. My one issue with it is that my bags tend to collapse in on themselves when empty, and the scale freaks out when I correct that to put stuff in them.

They make you weigh the bags first here. I suppose this presents the opportunity to finagle the system, but they always seem to watch me like hawks, and I’m hardly the median grocery store shoplifter demographically.

Hmm.. I'd like to claim that I've been prevented from just rescanning the same item twice, but I'm not sure of that. I'll try and see if that works for duplicate items next time I'm shopping.

I just double-scanned some store-labeled bagels today. I had two packages and one of the barcodes was damaged, so I scanned the other one twice. Worked fine. Even when I picked up the first one off the scale (to rescan it) and put the second one on, Indiana Jones-style.

I could 100% see fresh sliced deli meat being unique enough in a barcode (Item, weight to 1/100th of a pound, timestamp down to a second) that simple double scanning logic would catch you messing with this.

For pre-packaged anything meat with similar package weights, though, you'd doubtless be able to double scan.

The most I steal is exotic peppers being coded in as jalapenos or white onions as yellow, and that's 90% convenience of fast scanning and 10% the price difference.

I can scan the same item twice at my local grocery store. (The legitimate use-case is to scan one item X times when you're buying X copies, rather than manually going through the entire stack of the copies).

Maybe the scanners used in other countries are different, but here you will not be prevented from scanning the same item twice, provided that an equivalent item is placed on the scale. I often do this with multiple half gallons of milk for convenience reasons. The UPCs are the same.

This ignores Target and Home Depot, which allow you to use the hand scanner and never weigh the items anyway.
