Worksheet called "Check-in and warm-up" with these questions:

1. Name and date
2. Check in asking about attendance and preparation with readings
3. Write 1–2 paragraphs about (1) what you most want to talk about from the readings today, and (2) why.
4. Write 1–2 paragraphs connecting this week’s topic and readings to a recent or current event.

Updating my comparative public admin seminar classβ€”which was decimated by AI last yearβ€”to maybe be a little more LLM-proof by adding a 20–30 minute start-of-class writing & discussion activity.

Not surprisingly I have lots of thoughts on this. But in a nutshell, Yes, we should support teachers and no students should not be on their phones in class (unless they are integrated into the class plan or supporting learning), but, most teachers and schools had already solved this problem...

with phones in backpacks, lockers, or in holders at the back of the room. So the bans are doing little to change access to phones, are costing us lot of money (with these bizarre yonder pouches), time, and resources and are not solving any of the real problems that young people are facing - so...

the danger is that adults claim victory and believe they have saved the children, when in reality they have just kicked down an already open door and did nothing to support youth mental health (oh, and by the way, we are in the midst of an adult mental health crisis but keep pointing only at youth)

New figures quantify teenagers’ self harm. Once again, we’re hearing social media is to blame. See if you can spot another reason why teens might be more depressed.

Thick and Thin Causation In the course of ordinary social science and medicine, we are quite comfortable calling something a cause, even when (a) we don’t understand the mechanisms by which the cause exerts its effects, (b) the cause is probabilistically but not deterministically associated with effects, and (c) the cause is of uncertain portability across time and space. β€œAll” that is required to assert that you have identified a cause is to demonstrate evidence that the average outcome for a group of people would have been different if they had experienced X instead of Not-X. And the most convincing evidence that you know what might have been is to assign people randomly to X or Not-X. (The word β€œall” is in scare quotes here, because as any scientist of human behavior and society knows, actually isolating the variable of interest from the web of potential confounds, so that one can make an inference about causation, turns out to be an incredibly difficult and delicate operation.) I’m going to call this a β€œthin” model of causation.22 We can contrast the β€œthin” model of causation with the type of β€œthick” causation we see in monogenic genetic disorders or chromosomal abnormalities. Take Down’s syndrome, for instance. Down’s syndrome is defined by a single, deterministic, portable cause. To have three copies of chromosome 21, instead of two, is the necessary, sufficient, and sole cause of Down’s syndrome. The causal relationship between having three copies of chromosome 21 and Down’s is one-to-one, with the result that forward and reverse inferences work equally well. The cause of Down’s is chromosome 21 trisomy; the effect of chromosome 21 trisomy is Down’s. Having three copies of chromosome 21 doesn’t raise your probability of having Down’s; it is deterministic of the condition. And this causal relationship operates as a β€œlaw of nature,” in the sense that we expect the trisomy-Down’s relationship to operate more or less in the same way, regardless of the social mili…

It's a distinction from @kph3k.bsky.social's Genetic Lottery. I used it before even without talking about genetics; it catches a lot of the misconceptions that student have about what it means to call something a cause. Those misconceptions also led to a blog post: www.the100.ci/2024/06/26/s...

…yes, AND we have also known that young people with mental health problems often report spending more time gaming and online. Instead of calling them addicted because of it, we should ask what they are searching for and what we can do to help them find what they need.

Visionary, timely, effective, AND based on well-known developmental principles!
Youth need something else beside multiple choice and status quo if they are going to thrive and work collectively on solutions we/they desparately need over the next generation.
Highly recommend. 5 stars

Social media consensus paper causes social media uproar Preprint reporting common ground among researchers on smartphones and teen mental health is premature and flawed, critics say

Like others, I dropped out of the process because it was bonkers. Beyond the specific topic, it illustrates major meta-scientific problems that include, but are not limited to, wasting resources and drawing inaccurate conclusions from the available data. www.science.org/content/arti...

If I am reading this correctly, this version with a rational x-axis provides evidence for a different conclusion than the paper seems to offer:

A (slight) majority of experts say that there is any evidence at all for only one of the 26 claims investigated.

I do wonder to what degree that the people supporting technology moral panics (politicians, scholars, professional organizations) really are just outright lying about the science, or just are completely clueless. The distortions are amazing to behold sometimes.

Unfortunately, since there are people crying wolf about all kinds of things, as brilliantly documented by the Pessimists Archive project (@pessimistsarc.bsky.social), the enterprise of alarm-raising defeats its own aims, because it ends up desensitizing people to predictions about risks and harms.
