I will say this was one of my favorite aspects of Cat’s Cradle by Kurt Vonnegut, but there it was done intentionally and in service of the story. Here it seems like more of a market fulfillment thing…

🌬️ Can wind energy projects power local job growth?
📈 A new #JAERE study finds that when a new wind farm opens in Brazil, local employment rises by 7–15%, with gains concentrated in construction, transportation, and electricity-related jobs.

New paper out with @boryslaw.bsky.social 🥳 In which we sketch out how to rethink measurement invariance causally for applied researchers. And provide a causal definition of measurement invariance!

www.sciencedirect.com/science/arti...

Rethinking measurement invariance causally

Highlights:
It is preferable to work with a causal definition of measurement invariance
A violation of measurement invariance is a potentially substantively interesting observation
Standard tests for measurement invariance rely on strong assumptions
Group differences can be thought of as descriptive results

Conceptual graph illustration the central points of the manuscript. A group variable is potentiall connected to a construct of interest which affects items. Measurement invariance is violated if the group variable directly affects the items, for example by modifying the loadings from the construct to the items, or by directly affecting an item

To make this less abstract, consider a scenario where students take an exam, R, meant to capture some ability, T, and then are admitted to a program, V, depending on their exam results: R → V. This is sufficient to result in a violation of the statistical definition of measurement invariance. Exam results and admission are not independent given ability because exam results have a direct effect on admission. Even if we know somebody’s ability (e.g., we know it’s very high), learning about their admission status (e.g., they were not admitted) can tell us something about their exam result (e.g., it may have been worse than expected). According to the causal definition, this in itself does not constitute measurement bias, which seems a sensible conclusion here. After all, the scenario does not involve any reason to believe that the measurement process varied systematically by admission status. Admission happens after the exams took place, it cannot retroactively influence the measurement process (and, for example, lead to unfair treatment depending on admission status).

I hate that universities are held in opposition to the trades. My dad’s work as an electrician made me appreciate expertise and made me want the highest form of knowledge in my field. love to pay an expert for their knowledge— seems nice that our economy could sustain many kinds of expertise.

If today you are an American celebrating "independence day", I strongly recommend you read aloud or listen to the original declaration of independence. Meditate on the words or discuss them with family and friends. dissect the meaning in the document learn more about the occasion than sky boom boom.

I have always been committed to nonviolence but the way a lot of people are talking about nonviolence right now has really been bothering me, and I realized it was reminding me of @rebeccasolnit.bsky.social’s She Made Him Do It Theory of Everything: www.meditationsinanemergency.com/the-she-made...

The She Made Him Do It Theory of Everything

The rhetoric and logic of the abuse of power operates similarly at all scales, which is why I've found feminism such useful equipment for understanding authoritarians in public and political life. Bec...

For years, I hoped NPR, NYTimes, or the ghost of Gimlet would make a video game podcast. A weekly, hour-long audio magazine with essays, interviews, tight editing, and a cheeky sense of humor.

Nobody made the show I wanted to hear.
So, I made it myself.

Here's the first episode of Post Games.

It has been a dreary and rainy week in Philly, which means muddy boots for me and rich, watered soil for the city plants. As I listen to Mort Garson’s Plantasia, I feel thankful for the green leaves of the local trees, fat with droplets from the sky🍃💧

I’m viciously aware of the irony of this post, but I cannot shake the self conscious feeling that everything I put on social media has to be produced and curated, every thought whittled down to its pith. The feeling paralyzed me and keeps me from sharing my thoughts. I aim to change this in myself.

Willow appreciation post. As I’m getting ready to start #gradschool in the Fall, I can’t fully express how thankful I am for this little #dog. She got me through some tough nights living alone in Philly, and I am grateful that she will be with me for moral support as I start this new chapter
