One concept I wish more people were aware of is the Tocqueville Effect.

Named for Alexis de Tocqueville, this concept describes the curious phenomenon by which people become more frustrated as problems are resolved:

As life gets better, people think it's getting worse!🧵 Image
You go to a supermarket and it's time to get some fruit.

Of course, when you go to pick your bananas and your berries, you want to pick the freshest stuff.

But if what's on display is a little less fresh than ideal, you might consider a speckled banana or squishier grapes OK. Image
This is natural and fine.

You know what's not fine?

Cops beatinging jaywalkers because the crime rate dropped.

With too few "assaults", more mild crimes might start getting treated like assaults, even if they shouldn't. Image
Freshness and assault can both be examples of the Tocqueville effect, or as it's been called in the scientific literature: prevalence-induced concept change.

If you need a real-world example, consider the concept of "microaggressions": with less racism, people have to invent it.Image
Incredibly, we see this experimentally

In this first trial, participants were asked to rank a series of 1000 dots that varied from very blue to very purple on a continuum, with a stable prevalence of each color throughout

Results for the first and last 200 trials were identical Image
In this second trial, the researchers changed it up.

Now, the prevalence of blue dots would be decreased as the trial went on.

Notice what happened? People started seeing dots which they would've previously identified as purple as being blue instead. Image
This is, frankly, amazing.

If you just shift the prevalence of something, people start identifying marginal things as it more often—objectively, literally in terms of what they classify the things they see with their eyes!

And this holds up in a fairly broad way.
Researchers repeated this with different designs

In one, they prompted differently. In another, they asked people to stay consistent and paid for success. They changed the speed of color change, reversed the direction of the change...

Replicated each time!
But are we sure this applies to abstract concepts?

Yes!

In another trial, with photographs of people independently rated as more or less threatening displayed at stable prevalences, we get this: Image
When the experiment was redone with a decreasing prevalence of threatening faces, the result held up remarkably well from the previous color experiment.

That is to say, participants started rating the same faces as more threatening. Image
Rinse, repeat—Tocqueville evidently identified something very real a few hundred years ago.

And this works with even more complex concepts.

In this trial, participants played the role of reviewers on Institutional Review Boards, rating the ethicality of proposed studies.Image
Reduce the prevalence of study ethicality (rated by outside raters until they agreed) and...

Bam! Same thing as before!

People start rating ethically neutral proposals are being unethical! Image
When I explained this to a friend, I told them that the most interesting thing about this was that there were individual differences in how much the effect appeared.

Some people could see prevalence change a bunch and be unaffected. Others shifted strongly. Keep that in mind!
Now, I think you should be able to tell why I think this concept is so important and so neglected.

It is applicable to thinking about a huge number of issues.

Take lead abatement. Blood lead levels keep falling, race differences are almost gone, and funders care more than ever! Image
Or take literacy.

We're at historical highs for literacy rates, so why should we be throwing more and more money, effort, and urgency at the tiny residual of people who are illiterate?

Or consider police shootings. They're way down, but public interest is way up. Image
Think about billionaires.

They're increasingly likely to be self-made men, but as a society, we've become increasingly likely to be worried about their unearned privileges and whatnot, when the truth is, we've been moving away from that at a breakneck pace. Image
Human trafficking?

Slavery?

Racism?

These are all ills that have virtually vanished, but public outcry is pitched and tempers are flared, and even saying that we've basically beaten these issues (though problems remain!) is treated as denialism when it's just a fact!
So much makes sense in light of the Tocqueville Effect.

As problems get smaller, the attention given to them must grow.

This is a personal problem for many, too. Have you ever noticed that activists refuse to claim victory? Many get stuck crusading for life. Image
Imagine you're some HR bureaucrat tasked with fixing a problem at your company

If you manage it, you make the office a more hospitable place and you'll naturally start looking at smaller issues as evidence you're still needed, thanks to this effect—self-justification not needed!
Frankly, I think this is a source of a huge amount of modern pessimism.

Perhaps if people realized they were falling prey to this, that would help them to cheer up. Who knows?

I'll leave you with some words from Chris Rock: Image
P.P.S.

Lots of people have independently come up with the Tocqueville Effect in various forms.

Consider "Simon's Rule": Image
P.P.P.S.

Bodybuilder obsessing over that last little bit of fat on their sculpted stomach?

You guessed it: body dysmorphia as Tocqueville Effect! Image

Are White women the primary beneficiaries of affirmative action?

That's a real claim that's commonly advanced by journalists, and the claim has gone so far that it's even made its way into academic publications and policy.

But the claim is completely false🧵 Image
This claim doesn't make a lot of sense. After all, shouldn't the primary beneficiaries of affirmative action be the people who the policies primarily target?

In America, that's African Americans and, among them, women get an added benefit. How could it be Whites? Image
To figure out where the claim comes from, I started reading supposed sources.

Often enough, journalists will just take the claim for granted without providing *any* source.

It's just tacit knowledge now, and that's not good!

Then, when you hit a source, it's not supportive: Image

World War I devastated Britain and likely slowed down its technological progress🧵

The reason being, the youth are the engine of innovation.

Areas that saw more deaths saw larger declines in patenting in the years following the war. Image
To figure out the innovation effects of losing a large portion of a generation's young men who were just coming into the primes of their lives, the authors needed four pieces of data.

The first were the numbers and pre-war locations of soldiers who died. Image
The next components were the numbers and locations of patent filings.

If you look at both graphs, you see obvious total population effects. So, areas must be normalized. Image

New Pangram validation!

You know how most books on Amazon are AI slop now? If you didn't, look at the publication numbers.

Compare those to the proportion Pangram flags as AI-generated. It's fully aligned with the implied numbers based on the rise over 2022 publication levels! Image
Similarly, the rise of pro se litigants has come with a rise in case filings detected as being AI-generated, and with virtually zero false-positives before AI was around.

You can also see the rise of AI-generated text and yet more evidence for Pangram's validity from looking at different journalists.

Large portions of the journalistic profession are lazy, so they cheat when they can.

For example, the Guardian's Bryan Graham = slop Image

Pierre Guillaume Frédéric le Play argued that France's early fertility decline was driven by its inheritance reforms, where estates had to be split up equally to all of the kids, including the girls.

There's likely something to this!🧵 Image
For reference, the French Revolution ushered in a number of egalitarian laws.

A major example of these had to do with inheritance, and in particular with partibility.

In some areas of France, there was partible inheritance, and in others, it was impartible. Image
Partible inheritance refers to inheritance spread among all of a person's heirs, sometimes including girls, sometimes not.

Impartible inheritance on the other hands refers to the situation where the head of an estate can nominate a particular heir to get all or a select portion. Image

In terms of their employment, religion, and sex, people who joined the Nazi party started off incredibly distinct from the people in their communities.

It's only near the end of WWII when they started resembling everyday Germans. Image
Early on, a lot of this dissimilarity is due to hysteresis.

Even as the party was growing, people were selectively recruited because they were often recruited by their out-of-place friends, and they were themselves out-of-place.

It took huge growth to break that. Image
And you can see the decline of fervor based on the decline of Nazi imagery in people's portraits.

And while this is observed by-and-large, it's not observed among the SS, who had a consistently higher rate of symbolic fanaticism. Image

"Food deserts" are an example of social scientists getting causality backwards

They saw poor people eating unhealthy foods and blamed local supply

They should have blamed demand!

Using data from 13 years of supermarket entries, there's basically no effects on healthy eating🧵 Image
The significant effects are probably not meaningful. They're more likely under the null with this gigantic dataset (p's of 0.003 and 0.005 with a total sample size of ~2.9m)

Entry did affect sales for new stores, but not existing ones. It also affected more local places more. Image
When new supermarkets open up, they do nab a share of local grocery sales, but the effect on healthy eating in total, among low-income households, and in food deserts, just isn't there. Image
