The paradox of inequality that isn’t: rising economic inequality depresses and polarizes citizens’ belief in meritocracy Abstract. This study examines how rising income inequality has been impacting individuals’ belief in merit-based success, using three decades of survey dat

πŸ” How does economic inequality impact beliefs in meritocracy?

Using comprehensive survey data from 39 advanced capitalist democracies over more than three decades, Markus Gangl & I examine how rising economic inequality has been shaping citizens' belief in meritocracy.

Citizens tend to lose faith in meritocracy as inequality rises within their country over time.

"Just Plot the Data"

Which of the two datasets is normally distributed?

Plotting the data might seem like the most assumption-free way to examine its properties.

But is that really the case?

I am increasingly getting comfortable with the idea that estimation and uncertainty quantification can be treated in quite different ways, which would once have been quite strange to me.

There is something quite clean about distilling a large range of statistical principles down to

"Well if that _were_ the case, then *this* would really be quite unlikely."

We cannot have a rational debate about technology. As long as we rely on screens rather than on forests and sunsets to soothe our pain, we will fight to defend the screens, not the forests.

This article is my take on AI.

We cannot actually have rational debates about technology, because our ability to reason is compromised by the colonial fantasy world we live in where the material consequences of our actions don't exist where we don't see them.

Everyone is trying to argue this but this creator is a Christian who has said that movies shouldn't have "an agenda" and I think people need to think a little bit harder about the internal consistency of religious belief systems. There is no conflict here

Religious people define childhood in this country and they know it. They define what is safe (and no responsibility that it is not safe for queer children). They define what good childhood emotions are and what bad childhood emotions are. No conflict here because they're in charge of the definition.

ah the 'I don't like X >> it's because X is a and b >> a and b makes X morally wrong >> no one should like or do X >> those who do X are both stupid and evil' pipeline

most confusing part is that it genuinely do be like that sometimes. not always though. not even most of the time.

But you'll feel a lot more alone if your default is "I'm the only one who Truly Understands The Mess" and a lot less alone if your default is "my fellow humans must also be in versions of The Mess" and guess what

The default is a learned skill.

Look, it's a mess out there and you can react to that mess by deciding everyone else is a moron or you could react to it by deciding most people are trying to get by with a different context than yours and start working the problem. Those are your choices pretty much, can't choose "no mess"

The most fascinating applications of statistics are the ones where you have to creatively work around pragmatic constraints.

E.g. quasi experimental methods.

A new paper in JAME revealed a growing sleep deficit among high school students, which impacts cognitive ability and depressive symptoms.

There is a need for systemic change, such as "later school start times or reductions in bedtime digital media"
