Wouldn't it be quite a coincidence for this to be the moment public opinion got it right?

It's tempting for the moderate to strut. Isn't it enlightened to see truth in both sides? To calmly rise above the squabbling? But there's a strong argument against moderation: Public opinion has been evolving for hundreds of years. Many things that are moderate today were 'extreme' very recently. Isn't it...

Rich countries are not monolithic. However, outside the US and a few microstates, they vary in a limited range.

With abortion in flux in the US, I realized I didn’t have a clear picture of how things looked in the rest of the rich world. When I searched, I found lots of maps, like the following from Politico and Wikipedia:

If culture war is intractable, what should we do instead?

The Guadalcanal campaign was the first major offensive operation by the Allies in the Pacific theater of World War 2. This nightmarish battle ran for six months and—while an Allied victory—involved losses so high the US Navy refused to release casualty figures for years afterward. When this campaign ended in...

How polarized are we? An overview of what people of different political parties, education levels, races, and political engagement think about politics.

We’re here on Earth for such a short time. So, I often wonder—what do people spend their days thinking about? Judging from the ever-increasing amount of screaming everywhere, the answer would seem to be politics. But is that right? What opinions do normal people really have?

Some claims that test scores don't predict college success don't add up.

Here are some claims about how grades (GPA) and test scores (ACT) predict success in college.

Why do you have to fill out an ethnicity form to get a job in the US? What happens if you refuse?

If you ever joined a large organization in the US, you filled out an ethnicity form. Here’s a typical one:

Why it's basically impossible to determine fairness from observational data.

We want to know if things are fair. Do some groups of people tend to get a raw deal in company hiring or university admissions or court sentences?

There's many suggested policies to address police violence. What do we know about if they actually work?

You can’t measure police bias using simple population ratios. A better idea is to check if police behave differently when it’s dark, but this doesn’t give any firm conclusions either. What else can we do?

Explores some natural experiments that try to measure police violence.

Measuring police bias using simple ratios doesn’t work. You can never cleanly separate the impact of race from other associated factors.

Why trying to measure police violence though ratios is totally and utterly meaningless.

Watching people discuss police bias statistics, I despair. Some claim simple calculations prove police bias, some claim the opposite. Who is right?
