So you can reduce your dementia incidence risk from Q1 -> Q5 by a whopping 0.08%-points. But in media you surely will read about a 40% reduction.

*edited: %-points instead of %


The reduction in risk is 0.08 percentage points, not 0.08 percent. The "%" symbol always means "percent", not "percentage points". The 0.08 percentage point reduction is a 40% reduction.

EDIT: don't assume the causality


Maybe they wanted to say "down to" instead of "by"?


Sure, because both are true (although that 0.08% is only over 8 years of known omega 3 consumption - as timescales increase the absolute risk moves towards the relative risk).

That 0.08% reduction would mean approximately 28,000 fewer EOD cases - not to be sniffed at!

What would it mean for salmon stocks and increased environmental damage?


Depending on where you source your omegas from, potentially zero impact!

To be clear my preference would be to source n3s from algal supplements and, once food safety testing for humans is complete, n3s from GM rapeseed.

In time I hope we end up with lab meat/plant-based meat alternatives that use these n3s so we can get the benefits of fish without the environmental and ethical concerns of getting n3s from fish.


If from menhaden, there's a raging debate on the one hand about trout, the Chesapeake Bay (Maryland and Virginia), the ecology and environment more broadly, and the other hand a Canadian company based in a small rural county in Virginia (Omega Protein, which, BTW, does not provide year-round benefits to all of its employees which creates a drain on already super limited services and supports. Omega Protein is not alone in this.).

I don't know enough about any of this to have an informed opinion, but I do understand that menhaden put Reedville, VA on the map.


This is talking about early onset, which is a particularly terrifying outcome. And yes, 1 in 1000 for a horrible outcome sounds much better than 2 in 1000, doesn't it?

And to be clear, many things that people worry about is less likely than that. Homicides (over an 8 year period about about 0.04 per 1000 people), terrorism (vanishingly small), and on and on.

None of this means that people should stock up on omega-3s, and as likely the study is actually finding a correlation with something else (e.g. wealthier people enjoy more fish rich diets and are less exposed to toxins, or something else), but halving something terrifying that isn't that uncommon is legitimately newsworthy.


The 40% (66%?) is the number that matters. Same way you wearing a helmet reduces your changes of brain damage in a motorcycle accident by 90%, yet you’re not on a motorcycle most of the time.


When it comes time to decide whether or not to take action and what that action should be, I'd say that the total potential risk reduction is more important.

One should weigh the cost of the proposed intervention in time/money/other_expense against the potential benefit. The potential benefit is the total reduction in risk * the magnitude of the unwanted outcome.

40% is less relevant.


The thing is, the 0.08% doesn't capture the total potential risk reduction - only the risk during the timeframe of the study (8 years in this case). Where we're talking about exposures and outcomes that stack over time (exposure to LDL and heart disease being a classic one) the absolute risk is, in my opinion, more misleading than the relative risk.

For example you see this oft-quoted stat about "statins only increase lifespan by 3 days" based off relatively short RCTs, but this doesn't capture the effect of statin use over decades, which is where we see much, much bigger gains.

It seems to me that both RR and AR are things to take into consideration and we have to be mindful of the shortcomings of each.


... over 8 years. Order of magnitude difference if it extrapolates to lifetime.


I abadoned facebook since I couldnt stand the feed experience anymore. Recently learned about using https://www.facebook.com/?sk=h_chr in combintation with extension https://www.fbpurity.com/ which give me a chronological feed of groups and people i actually want to hear from. The most astonishing experience is how calm I feel consuming this cleaned up feed. Almost all negative emotions seem to stem from the uncontrollable feed experience.

If we (Europe) are not careful, we will have to find out this pretty soon again.


It's so tricky. You can do most things right like Denmark/Netherlands, then you mess up just one (housing) and the far-right surges. Now you can't import immigrants to deal with your aging population, which means you're on a timer.

Or your neighbor goes far-right (US, maybe eventually Germany/France) and suddenly they start objecting to your internal policies (eg regulating big tech).

Or Russia+Covid combo suddenly inflating all kinds of prices, and again the far right surges.

I think it's going to be a dramatic few decades.


Yes, extremely tricky. Imo the current ruling class just needs to mess up just on thing, because there is a deep underlaying discontent with the subjectively felt way of living in our modern societies. So housing / migrants are just the spark.


What if we do not fight back because deep down we hate the current state of affairs? So why fighting to preserve this?


I would like to find a way out and often thought about starting a community / movement around this. Maybe this step feels easier collectively.


Isn't it astonishing how much happier the author / most of us could be without our phones?


I found nice soccer streams thanks to that list I never would have been able to find otherwise.


AI slop is a big problem. At the same time AI does some things pretty well (proofreading, translation, finding bugs, sum ups ...)


Do you mind sketching out the basic idea how to eliminate the change of currency for food? Sounds interesting.


https://autonoma.ca/model.png

By wholly automating food distribution, from seed to delivery, we eliminate the costs of high-quality, nutritious food, relying on volunteers for infrequent system maintenance. (This requires bootstrapping capitalism; I won't dive into the details here, because it would take a book ...)

Aside, that diagram is in the novel and was drawn about ten years ago.


Your system sounds centralized, and because lots of other people/the government are involved, I predict it will produce a cyberpunk, pink slime and soylent green dystopia.

I have lost faith that other people who are not in my situation will do kind, high quality work for my benefit over long periods of time (my lifetime.)

I have a crazy dream of single families or neighborhoods owning land and owning lots of cheap open source robots that tend crops and maintain one another over time. And when I say cheap, I mean not worth the trouble to steal. Big backyards in urban settings will be coveted, community gardens everywhere. The software to run it would be open source and free, it would be designed to not deplete the land.

Maybe in my scheme no insecticides are needed because the robots can spot them as they enter the fields and kill them with pinching armatures or pew pew lasers.

My dream is probably stupid in a million ways and impossible unless I get lots of F-U money to do it myself. I imagine big ag interests would make it impossible to succeed and then I'd need 2x F-U money to out-lobby them. ;(
