Having been on job search committees we have tended to wait until the deadline before reading. But others may do it differently

Hey folks: A little while aback, @jschleiderphd.bsky.social and I created a repository of SOPs to help folks prepare for grad applications.

If you'd like to add your SOP, feel free to use this form: docs.google.com/forms/d/e/1F...

Of note, mask as you desire as I will be posting them as is.

For those interested in the one replicable Construal Level Theory study:

People think it is more useful to think about WHY they would perform a high-level task (e.g. delay discounting) and more useful to think HOW they would perform a low-level task (e.g. Proofreading).

Since the 1990s, rates of anorexia nervosa have been falling.

Yet people and practitioners way overestimate not only the rate, but also this change.

PSA: Birth rates are not fertility rates.

Birth rates include the entire population as the denominator, and fall with population aging, even if young adults are having the same number of kids as before.

Yoooo! Another Dutch people doing unethical things in train stations study just dropped!
Very retro!

But seriously, Dutch people let white people skip paying 67% of the time but only 49% of the time if the skipper was middle eastern.

I will happily change the way it is described! A benefit of preprints. Would you email or dm me exactly where I describe the paper incorrectly and how it can be better?
I love the work you did, I only chose it because it was the *only* within subjects X-phi study in the X-Phi replication project.

What is SES?

We experimentally test the big 3 components in lay & expert participants.

Once you dissociate $ from job from education, it's mostly just money (but not exclusively!).

Experts also overvalue education.

This was one of my favorite projects!

Talk about The Wire, Sopranos, Game of Thrones all you want, but the greatest US television program ever made is Sesame Street. It's not even close. 50+ years of treating kids across class, ethnicity, religion not as mini-consumers...but as citizens with a stake in this world.

I've always enjoyed the dual beliefs many people hold of:
1) someone in their right mind who wants to end their life should have the right to do so
And
2) anyone who wants to commit suicide is not in their right mind

Completely unrelated to anything I normally do, I just love this stuff:

The genome of an Old Kingdom Egyptian showed that he was about 20% immigrant.

We should probably stop thinking immigration is some relatively modern phenomenon and realize it is deeply human.

People just keep using new items & scales to measure the declines & rises of happiness over age.

Unfortunately, the U-curve of happiness is not consistent across the 17 measures previously used.

We need to get our #measurement practices in order.

I swear I havenโ€™t heard a good thing about Cross-Lagged Panel Models in a While.

So here's more news.

There is a way to test if, at least, there might be a time-varying confound!

Plus a great decision tree!

The field of #sociology is a fascinating field with some interesting assumptions that uses deceptively simple procedures to ask big questions whose results are hidden behind an indecipherable wall of jargon.

Is there a literacy crisis? Or am I just old? Yes.

I had a hard time figuring out if all the stories about how kids can't read are a real problem or if it was just adults going "kids these days." So I looked into it! www.vox.com/culture/4190...

Iโ€™m going to say it despite how controversial it is:

5 is maybe the largest number of experiments any one (non meta-analysis) paper should have.

We are downing in papers with so many 'studies' it is near-impossible to keep the thread of what is happening.

It included unrelated children too. When genetically related, it followed the mothers line & more often girls, showing the importance of women in 1st cities.

Any unequal outcome can be modelled as coming from random starting points w/reinforcement OR traits causing the unequal outcomes. Both models fit equally well.

Lots of implications!
