Same energy (from my data science grad course, RIP)
Screenshot of a lecture slide. The title is "Code Style," and it's follows by a sentence that is technically English but, among other things, most of the spaces have been replaced with é and the last letter of every word is in uppercase. After a minute or so, a sighted reader can figure it out says "In written language, conventions for punctuation & capitalization aid comprehension by indicating structure." Then the bullet points of the slide: 

- This is what it's like to read poorly-styled code
- Conventions only work if they're <em>shared</em> conventions
- Style guides provide shared conventions for readable code
(sublist) 
- In-line spacing makes it easier to pick out distinguish [sic] functions, operators, and variables in a line
- Returns distinguish arguments in a function call
- Identation corresponds to structure of complex expressions
- Common conventions for naming, assignment reduce cognitive load
(end sublist)

This press release has been making the rounds. But like a lot of university press releases, it's overhyped. The headline finding is a change of a few percentage points and doesn't show up in one of the three component studies.
Press release screenshot: Using AI for just 10 minutes erodes your ability to persist at hard things

A UC Berkeley researcher co-authored a study that raises profound questions about how we interact with artificial intelligence in education — and daily life.

By Jason Pohl Screenshot of results from study 2/3 in the actual paper. Four plots show solve rate and persistence rate across 15 short math problems for participants in AI and control conditions. AI participants have higher solve rates until the AI is removed, and then they're slightly below the control participants. Skip rates are below 10% for both groups across the entire series of problems, and in this component study the difference wasn't statistically significant.

Back on my bullshit (regressing multidimensional scales of right-wing authoritarianism against multidimensional scales of trust in science)
A coefficient plot for a linear regression statistical model, showing the estimated effects of various components of right-wing authoritarianism (RWA) on various components of trust in science. RWA is "traditionalism" (basically religious-moral conservatism), "conservatism" (deference to institutions), and "authoritarianism" (we need a strongman who'll punish our enemies). Trust is "benevolence," "competence," "integrity" (telling the truth), and "openness" (listening to criticism). 

Across all components of trust, traditionalism lowers trust in science (positive effect),  authoritarianism has a weak or ambiguous negative effect, and conservatism has a weak or ambiguous *positive* effect.

Similar results here, also haven't read this yet www.sciencedirect.com/science/arti...
Highlights

• COVID-19 vaccine hesitancy (VH) involves factors like confidence, circumspection, and complacency. 
• Blacks are more likely to develop VH due to confidence and circumspection than Whites. 
• VH among Blacks declines dramatically across time but varies little across states. 
• The effect of education on VH is very small among Hispanics. 
• Women are more likely to develop VH due to circumspection and men more likely to have VH due to complacency.

This paper came up in a search for social determinants of hesitancy that vary by gender. Haven't read it yet, but super interesting: men's hesitancy is more explained by far-right conspiracism and complacency, women's hesitancy by low SES and safety concerns. pmc.ncbi.nlm.nih.gov/articles/PMC...
Previous research on coronavirus disease 2019 (COVID-19) vaccine hesitancy lacks a gender perspective, and it is unclear whether gender intersects with socioeconomic status to co- produce inequalities in people's intent to take vaccines. The current study draws on intersectionality theory and uses data from the 2021 US Household Pulse Survey (n = 50,359). Both bivariate and multivariate statistical analyses were conducted. The results suggest that American women had a higher vaccine hesitancy rate than men. Gender interacts with socioeconomic status to shape people's vaccine hesitancy in a complex way. Specifically, women living in poverty or currently working were more vaccine-hesitant, while poverty and employment status did not affect men's vaccine hesitancy. However, not having a college education contributed to both women's and men's COVID-19 vaccine hesitancy. Moreover, women were more worried about the safety of the vaccine, but men's hesitancy tended to be driven by lower perceptions of COVID-19 dangers and belief in conspiratorial claims.

Same thing with gender: pre-vaccine politicization, women were more likely to express vaccine hesitancy than men
Studies have shown women use health services more than men, -10 and emerging research suggests that they may also engage in COVID-19 prevention strategies (e.g., mask-wearing, social distancing, handwashing)
more than men. However, acceptance of the COVID-19 vaccine may stray from these typical gender patterns. Prior to the emergence of COVID-19, greater vaccine hesitancy had been documented among
women compared to men.12,13 Specific to COVID-19, a recent global meta-analysis reported lower vaccine intentions among women compared to men, but this varied by country.14 The review did not examine non-

You're talking about vaccine skepticism, the quoted post is talking about vaccine hesitancy. Before vaccines were politicized in 2020-21, hesitancy was highest among Black people. pmc.ncbi.nlm.nih.gov/articles/PMC...
The rate of COVID-19 vaccine hesitancy increased across US populations between the spring of 2020, when the pandemic first emerged (and vaccines were only hypothetical), and December 2020, when the first COVID-19 vaccine became publicly available. 15,16 This trend was especially pronounced among Black individuals, who consistently had the highest rates of vaccine hesitancy among US racial and ethnic groups.17,18,19 By December 2020, only 36% to 49% of Black individuals (compared with 44%-59% of White individuals) intended to be vaccinated when they became eligible. 13,15,16,20 COVID-19 vaccine hesitancy (among all groups) is primarily attributed to concerns about safety, effectiveness, and adverse effects, 13,17,18,21,22 although it has also been associated with virus-related conspiracy beliefs. 23,24 The rate of vaccine hesitancy in December 2020 was higher among Black individuals than among White individuals even after controlling for perceptions that vaccines are important, safe, and effective. 17,25 

Among Black individuals in the US, historical racism and institutional racism also drive vaccine distrust. Historical traumas, such as the Tuskegee syphilis study and the unethical and nonconsensual use of cancer cells from Henrietta Lacks, provide important context for understanding vaccine hesitancy among Black individuals. 13,26,27,28 Everyday exposure to institutionalized racism in health care is equally important, cultivating distrust of health care professionals and researchers. 29,30 Black individuals in the US recognize that members of their communities often experience neglect and inadequate treatment in health care settings and that these factors contribute to worse health outcomes. Together these factors are associated with Black individuals' hesitancy to getting vaccinated against COVID-19.

Here's how we defined it doi.org/10.1162/qss....
We first propose a distinction between scientific racism, race science, and race science discourse. Scientific racism refers to the social practice of purporting to justify racial inequality and colonialism by appealing to the epistemic authority of science. Race science refers to scientific and/or pseudoscientific research, including research products (journal articles, etc.), that can be utilized for scientific racism. Race science discourse refers to a broader category: any treatment of race science as a legitimate area of scientific research.

Philosophers Should Use AI More

Should you use AI to write philosophy papers? It depends on your goals. My goal is to discover new, important truths. I think that using AI well increases the amount of new, important truths that are discovered.

I think many philosophers share my goal, but I have only seen a few other examples of philosophers successfully using AI to write philosophy. By contrast, several other nearby fields have had more success using AI. This includes economics, political science, and math. I would be very interested in learning from other philosophers experimenting with using AI to write papers.

Though the other use maybe fits with Rose's interpretation (Bonus: Probably the first instance of me doing a bibliometrics)
I suggest that philosophy of science has largely - though far from completely abandoned its own aspirations for ideal theory. For much of the twentieth century, many philosophers of science (especially those who were most prominent and influen- tial after World War Two) aimed to give an account of perfected scientific reasoning, using the tools of mathematical logic, probability theory, and statistics. In the wake of the work of Thomas Kuhn and Paul Feyerabend, 30 however, the focus has shifted: highly technical work in philosophy of science is largely confined to the philosophy of specific sciences (especially physics and biology); and general philosophy of sci- ence is, for the most part, based on case studies of actual scientific practice and isconcerned with, say, the theory-evidence relation that is at work in this and similar cases rather than a perfected and universal theory-evidence relation. For example, of the seventy-seven articles presented at the 2008 biennial meeting of the Philosophy
of Science Association and subsequently published in Philosophy of Science, 31 I count sixty (approximately 78%) that either dealt with specific philosophy of science or adopt a case-study method. None of these sixty, as far as I have checked, purports to offer anything like a total and complete account of even the particular case that they are investigating, and many of the other seventeen appear to be similarly modest. In short, all appear to be engaged in non-ideal theory.

This is what I was thinking of, from this LA Times story: www.latimes.com/california/s... We don't have test data for current students/recent applicants. Even if we started collecting them this year, we wouldn't get any outcome data until June 2028, and that's just for first-year grades.
Screenshot text: 
[Michael Stryker, a UCSF physiology professor and BOARS member] argued the now-abandoned study was structurally incapable of producing useful evidence.

Because UC largely stopped collecting test scores after 2020, he wrote in a message to fellow board members that he shared with The Times, there is no comparable applicant group on which to validate today’s tests.

“In the absence of sound data,” Stryker wrote, the testing work group “will have little to do but debate the politics of testing.” He said the board should recommend restoring standardized testing for fall 2027 admissions and study its effects over four years, using methods UC used when it last evaluated testing in 2020.

Thinking about this some more, I suspect the DAG looks like this. Which is not great for trying to make an inference using only present data.
A very rough DAG drawn in Miro. From top (past) to bottom (present), there are four variables: career preference pre grad school; PhD program prestige; ac/non-ac employment; and career preference post grad school. Each influences all the ones that come after it. So career preference *pre* grad school is a confounder for prestige and employment, but career preference *post* grad school is a collider. Trying to adjust for career preference *pre* using *post* as a proxy just replaces confounder bias with collider bias.
