I think so, but that hasn't stopped it from being a popular way to gather data, or from often being the only source of data used in a paper. I get that internet surveys are dirt cheap and it's easy to get large number of responses, but you have to take the results with a such a massive boulder of salt that it seems more like a convenient way to churn out papers (or even an easy way to get a desired result) than a way…

> an easy way to get a desired result Reminds me of that bit from yes prime minister https://www.youtube.com/watch?v=6GSKwf4AIlI

Well a good surveyor would take into account order effects, i.e. the order in which questions were asked for example using Latin square designs.

Its the low quality food, my memory improved a lot, after I stopped eating sugar and most refined foods. Theres even some research that Alzheimer starts from bad bacteria in the gut, that loves sugar.

Could be multiple factors. In my N=1 experience fiddling with various things in my life.

* Improving diet (primarily avoiding refined foods and sugar) generally improves my energy levels.

* Cutting out social media mostly improves concentration.

* Trying to avoid rumination such as problem solving or rehearsing arguments through meditative practices reduces stress levels, makes it easier to be present and react to things in front of you.

* Sleep is also pretty big for cognitive clarity. Having a consistent sleep schedule and not drinking coffee past noon helps with sleep.

But really, all of these seem to tie into each other. If you want to improve your diet, it's much harder if you are tired from lack of sleep or overstimulation. If you want to improve your sleep, you can't be scrolling social media all day. Mental exhaustion also makes awareness/meditation harder.

Bacteria (and your body) like sugar because it’s an easy to use fuel source. There’s absolutely nothing wrong with having reasonable amounts of sugar in your diet.

The catch is that the body likes lots of things that are awful for it. For instance drug abuse isn't limited to humans - some bears have gotten addicted to huffing gas to get high. [1] Quite cute if it wasn't so awful! The big issue is that in modern times a whole bunch of things are going wrong - testosterone levels (adjusted for health/bmi/age) are declining, IQ is declining [2], basically every single psychological disorder is skyrocketing, and much more.

And the reason why isn't clear. So the most likely reason is that we're doing what humanity has done repeatedly and endlessly throughout history and likely accidentally poisoning ourselves with some thing or things -- things that we believe to be completely safe. So a precautionary principle approach to consumption is to consider what we evolved with and sugar definitely wasn't that. Sugar only really took off in the 19th century. And various further refined sweeteners like high fructose corn syrup and other such things only took off in the late 20th century.

I'm not sure it's social media as much as just mobile phones. I used to memorize phone numbers, addresses, directions, short notes, etc. Memory works like a muscle - use it or lose it.

I’m in my thirties. I have to mail books around the world and country because so few of my friends read. (It’s worst in the 50+ cohort.)

I've taken to audio books over reading, not sure how this will affect me but I do enjoy them.

Shitty food has been around for a long time. Some virus known for causing long-term effects in non-negligible parts of the population has been around since 2019. > The increase in disability prevalence from 2016 to 2022 is likely attributable in part to the long-term effects of coronavirus disease 2019 (COVID-19).

Wild to me that the first mention of COVID is this far down the page.

Most people have been infected at least a couple of times may this point, and at this point it’s very well documented to cause lasting cognitive decline.

> Those 4.5 million survey responses were gathered over a decade I'd feel more confident about the results of this research if it didn't entirely depend on self-reported data from a survey. At least in this case it was a phone survey and not just an internet questionnaire posted to social media sites. I'd put more faith in a much smaller sample of young people being professionally evaluated for memory problems. The s…

> internet questionnaire posted to social media sites This has got to have a strong selection effect.

An uncontrolled selection bias that has changed over time as the social media landscape has changed.

I was just talking with my wife yesterday about how readily people assume they have superior competence to or greater insight than experts in a given field. I'm not picking on you in particular, but your comment jumped out at me.

Substantially:

We've been eating "low quality" food of one type -- ultra-processed food -- since at least the '60s, so what's your explanation for the recency of the effect?

And some time earlier than that -- very roughly the 1920s and earlier -- we were eating "low quality" foods of a different type: spoiled, adulterated, and questionably-sourced food products, so do you claim that we started with poor concentration then, got better/had a heyday in the mid-20th century, and now we're declining again?

In short: what's your evidence to support your claim?
