BREAKING: new study just dropped that shows compelling evidence that cell phone bans cause student grades to modestly increase.

Grade increases are largest among low performing students. Some other interesting findings from the cell phone ban study:

Students exposed to the cell phone ban were substantially more (!) supportive of phone-use restrictions.

The ban increased students' perceptions of greater benefits from these bans and reduced students preferences for unrestricted access.

This figure is striking.

It shows the relationship between where people think they are in the income distribution and where they actually are.

Observations below the line indicate that people think they are poorer than they really are (and the reverse above the line).

What do you notice? If you answered "people think they are poorer than they really are", you'd be right!

Studying economics and business in college makes students become much more conservative.


Here are the estimated effects of individual majors on ideology.

What stands out to you?

Wow! This project looks amazing.

In it, three scientists at Columbia, Michigan, and Maryland introduce VRscores: a measure of the partisan leanings of employers in the United States.

The dataset is constructed by linking U.S. voter registrations to online worker profiles.

The dataset covers the 2012-2022 period. VRscores capture the political affiliations of 21.8 million workers across 2.6 million employers.

Wow!
Overall, many employers in their sample have a distinct Democratic tilt. Look at how few sectors are dominated by Republicans!

{This could have something to do with what orgs are in their database, but their sample is quite large!}

Look at the gender breakdown of who speaks in popular films! If it's too hard to see, here's the takeaway: men dominate spoken work in popular films.

Clear evidence that people who include their pronouns in their email signatures receive preferential treatment in higher education settings.

How many people go to church weekly?

Surveys say it's about 1 in 5 Americans.

Cell phone tracker data say it's actually closer to 1 in 20 Americans.

Fascinating new working paper!

Can you guess what happens when you give kids food stamps?

They...

⚫live longer,
⚫invest more in human capital,
⚫are more economically self-sufficient,
⚫live in better neighborhoods,
⚫are less likely to be incarcerated.

Running a study where you use names to signal race?

Be careful! Names signal more than just race alone.

But (!), fret not; we have pre-tested 600+ names for perceptions of race/class/citizenship.

Punchline: we show that despite prior research claims to the contrary, mass shootings have little effect on electoral outcomes in the U.S.

1.) explore the question of whether mass shootings affect election outcomes in the United States

2.) Provide an overview/application of recent advances in the diff-in-diffs space. 2/n

Anyone else feel like social scientists actually know far less than we think we know? I was thinking about this in the context of all of the failures to replicate many findings in social science fields in recent years.

And how before those replication failures occurred, we were so very certain that we knew something about the world.

This is your periodic reminder that the graduation regalia for PhDs in Finland is a top hat and a sword. "The Doctor's Sword is a symbol for the scientist's fight for what he or she, in rigorous research, has found to be good, right and true."

PhDs who leave the academy are *definitively* not failures. But, all too often, the academy fails them. I've said it before, and I'll say it again...

If PhD programs are, truly, going to prepare students for non-academic jobs, they should, at minimum, stop sending signals—overtly or covertly—that non-academic jobs are inferior.

Americans are less likely to respond to emails from African Americans.

Sex crimes decline by 13% as a direct result.
