Culture War Roundup for the week of April 3, 2023

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.

gas stoves

There was a minor media circus about them, but they haven't actually been banned, have they?

Anyway, induction is amazing and I hope both gas and conventional electric stoves get banned.

There was a minor media circus about them, but they haven't actually been banned, have they?

The CPSC dropped their plans, but they switched to the Department of Energy, which isn't going to ban them but just limit the amount of gas they are allowed to use so they will be crappy enough that people won't buy them.

Not sure how true it is, but it's said that induction stoves screw with pacemakers. If true, that would make them unfit for universally mandated use.

Apart from the policy being misguided in the first place. What's the justification?

OK, pacemakers are the only good argument against the ban I've seen so far. The only research paper that I can find is this one from 2006:

Conclusion: Patients are at risk if the implant is unipolar and left-sided, if they stand as close as possible to the induction cooktop, and if the pot is not concentric with the induction coil. Unipolar pacing systems can sense interference generated by leakage currents if the patient touches the pot for a long period of time. The most likely response to interference is switching to an asynchronous interference mode. Patients with unipolar pacemakers are at risk only if they are not pacemaker-dependent.

I don't know what that means TBH.

Having exhausted the scientific literature, I tried the next best thing: Reddit. There are anecdotal reports from people with pacemakers cooking with induction and people with pacemakers who were told by their doctors not to cook with induction. No reports from people with pacemakers who tried cooking with induction and died.

Edit: And what about people who have embedded metal fragments that can't be removed? I guess my ban isn't a very good idea after all.

An induction stove can affect some pacemakers if someone is COMPLETELY up against the stove and the pot is not covering the pad completely. Touching the pot creates a circuit (a long touch), and the pace maker will switch modes.

Interesting share.

No reports from people with pacemakers who tried cooking with induction and died.

A very literal example of survivorship bias.

OK, pacemakers are the only good argument against the ban I've seen so far.

No, that's not how this works. It's a free country. I don't need to make any argument against banning gas or electric stoves, whomever wishes to ban them needs to make an argument for it. And the bar is very high. Frankly, no supposed harm of stoves is likely to convince me that adults shouldn't be able to choose what they do or don't want to cook with.

See my other comment for why gas and conventional electric are bad.

What about the children who live in the same household? Indeed, children are the ones most affected by pollution from gas stoves.

If it's not clear, I was actually mostly joking when I suggested banning gas and conventional electric stoves. Did anyone take my claim that using conventional electric stoves is "basically a human rights violation" seriously? I was slightly in favour but I didn't really care. A complete ban is well beyond the Overton window anyway. I have now changed my mind and am slightly against it unless it can be demonstrated that they are 100% safe for people with pacemakers (and metal fragments!). Presumably this question will come up if a ban becomes remotely plausible. If it is a real danger, politicians will want to avoid being responsible for cooking someone's grandpa.

my other comment

You have to be joking about that pollution thing right? Gas stoves burn almost completely efficiently meaning they produce CO2 and water almost exclusively. The char on your steak generates hundreds of more times indoor pollution in 2 minutes than just letting the stove burn all day would.

What about the children who live in the same household? Indeed, children are the ones most affected by pollution from gas stoves.

What about the possible bad ideas the parents could instills in their children? Activists can do information campaigns, individuals can shame people but at some point we're just going to have to let people parent and not try to get the state to it for them.

I agree induction is great. I had an induction stove and loved it. My wife is an immigrant and induction doesn't work with the kinds of pans she likes. We bought a new stove.

Please don't ban things without a compelling reason. Your and my personal preference are not valid reasons.

What kinds of pans? What's wrong with ferromagnetic pans?

What's wrong with ferromagnetic pans?

Nothing, other than they don't sell them at the Asian market. We have a large collection of pans from Asian markets and all of them are coated aluminum.

If I had my way I'd have an induction stove. But I have a wife.

Anyway, induction is amazing and I hope both gas and conventional electric stoves get banned.

"I like X, not X should be banned", without elaboration or reasoning, is childrens cartoon villain logic.

I thought the downsides of gas and conventional electric stoves were well-known.

Gas stoves cause indoor air pollution (I believe this is what the aforementioned media circus was about) and require gas, which is a fossil fuel – do I need to explain why fossil fuels are bad? And they require either a network of gas pipelines, which are an additional bit of infrastructure that needs to be built and maintained (and they tend to explode), or distribution in individual tanks, which is very wasteful. Induction just needs the existing electrical grid.

Conventional electric stoves are extremely inefficient, so they waste a lot of energy. And they are horrible to work with, it's basically a human rights violation. If conventional electric stoves are Americans' perceived alternative to gas, then I can understand the overreaction to the mere suggestion that gas stoves might be banned. In fact, in that light, it was probably an underreaction.

do I need to explain why fossil fuels are bad?

I think you do. And if your explanation is "because they'd be out someday" you'd have to do better than that because "someday" is doing a real lot of work here and it's not practical worrying what would happen in 3000 years - in 3000 years the people might be all living in the Matrix anyway.

and they tend to explode

If they are properly maintained, they don't. If they are maintained by PG&E, then well, that's a whole different business.

require gas, which is a fossil fuel – do I need to explain why fossil fuels are bad?

Gas stoves are burning gas to produce heat. This is dramatically more efficient than burning gas to turn a turbine to produce electricity to send over the electric grid before turning into heat. (Even the couple percent of gas lost to leaks is less than the 6% loss on sending electricity over the grid.) It's not like an electric car where power plants are much more efficient than a portable gasoline engine (plus regenerative braking) so electric cars end up being more efficient. Making heat is inherently very efficient because you're not fighting thermodynamics, making electricity isn't. As a result, under the electricity-generation mix currently typical in the U.S., induction stoves cause more CO2 emissions than gas stoves.

https://home.howstuffworks.com/gas-vs-electric-stoves.htm

The clear winner in the energy efficiency battle between gas and electric is gas. It takes about three times as much energy to produce and deliver electricity to your stove. According to the California Energy Commission, a gas stove will cost you less than half as much to operate (provided that you have an electronic ignition--not a pilot light).

Now, maybe the higher CO2 emissions to power induction stoves is worthwhile for whatever indoor air quality benefits there are. And maybe power-generation will change so that generating marginal electricity rarely involves spinning up a gas turbine. But remember stoves don't last forever, if this change doesn't happen for a while then the induction stove will emit more CO2 over its lifespan regardless. I get the sense that a lot of people are vaguely anti-gas-stove because they assume it causes more CO2 emissions due to directly burning a fossil fuel, even though this is the opposite of the case.

Regarding the indoor air quality aspect, it would be nice if there was a decent literature review of the issue, like Scott's "Much more than you wanted to know" series. As a matter of common-sense, it seems like gas stoves must be at least marginally worse. But from what I've read this doesn't seem dramatic enough to show up in aggregate health outcomes for more rigorous studies. The main difference is only in terms of nitrogen dioxide and carbon monoxide, not the particulate matter you might expect. Most particulate matter comes from the food, so it's plausible that consistently using a range hood that vents to the outside is actually much more important than gas vs. induction. But it's hard to synthesize the available information into a general sense of how much of an issue it is.
