Four Hundred Words for Six Hundred Dollars
The announcement arrived through LJExpress on a Friday in late July, dressed in the language of service. Media Source, the company that owns Library Journal, School Library Journal, The Horn Book, and the Junior Library Guild, had opened a storefront called Open Shelf Reviews, aimed at independent authors and small presses, and the copy asked me to hold two ideas at once: the reviews would be paid for by the authors under review, and a wall would keep those purchased reviews away from the magazines whose names give the wall its worth. The company described the operation as "a clearly identified paid service," with its own editor, reviewer pool, and website, all kept apart from the editorial processes that made Library Journal matter to librarians for a century and a half.

Three legs are needed for deductive causal inference:
"Without assumptions regarding construct validity, one cannot accurately label the cause or outcome. Without assumptions regarding external validity, one cannot label the conditions enabling the cause to have an effect. If any of the assumptions regarding internal, construct, and external validity are missing, the claim is not deductively supported. The critical role of theoretical and substantive knowledge in deductive causal inference is illuminated by making such assumptions explicit. This article critically reviews approaches to identification in causal inference while developing a framework called causal specification. Causal specification augments existing identification strategies to enable and justify deductive, generalized claims about causes and effects. In the process, we review a variety of developments in the philosophy of science and causality and interdisciplinary social science methodology."Esterling, K., Brady, D. & Schwitzgebel, E. (2025). "The necessity of construct and external validity for deductive causal inference" https://doi.org/10.1515/jci-2024-0002

From a social science perspective, the key error of nationalism and racism is to prioritise one people's history over another's. Each individual and each society evolved within its own context, and all historical contexts are equally valid, understandable, and worthy of respect.

Bad News
Me:-
"Are broken-up people (like me) given the same care and attention as the divorced?"
Claude:-
Honestly? No, and that's a real gap.
Divorced people get:
- Social acknowledgment ("oh, they went through a divorce")
- Community support, family sympathy
- Religious frameworks (iddah, counselling, clear closure)
- Legal process that forces some kind of finality
Broken-up people often get:
- "It was just a relationship, move on"
- No formal closure ritual
- Grief that isn't publicly recognised
- The expectation to be fine faster
This is called disenfranchised grief — grief that society doesn't officially validate. The loss is real, but because there's no contract, no ceremony, no legal ending, people around you often don't treat it with the same weight.
Me: "Very sad news indeed. I am just a fly in the skies that's broken."

The #paper "From Fear to Control: Developing a Three-Factor Scale for Cybersecurity Anxiety (CybAS)" by Nikolaj Dall, Hanno Gustav Hagge, Peter Mayer (SECUSO) and Cori Faklaris was accepted at #CHI2026. The authors developed a 15-item psychometric instrument, the #Cybersecurity Hashtag#Anxiety Scale (CybAS), to measure anxiety specifically in the cybersecurity context. CybAS measures three concepts: current concerns, anticipated threats, and perceived control over outcomes. Analyses confirm strong #reliability and #validity, and the concise format makes CybAS suitable for both #research and applied settings.

OMG Social media improvement idea!
Option to publish individual posts to be, allowing no further edits except emphasis.Like, you can change the formatting forever onward to be:
"make this bit bold", "italicise the other thing", or "strike-through that", "underline whatever".
Maybe add a redaction feature, in case you want to keep a post up, [but remove sensitive info you left in].Or redact any hacked or bot posts, leaving that portion up as, like, "hey this is when stuff got annoying".

Improving Numerical Measures of Human Feelings: The Case of Pain https://d.repec.org/n?u=RePEc:lan:wpaper:421926304&r=&r=exp
"… proposed and validated a new method to measure the experienced intensity of acute pain across individuals. This method proved to be overwhelmingly more accurate and sensitive than standard, established methods for experimentally-induced acute pain which are used in medical, clinical and research applications
… In the case of experienced pain intensity, the mechanism that enables the new #measurement method to excel might indeed be rooted in its well-calibrated scale: #money.
… Money-free standard methods ask people for numerical estimations of their experiences without a benchmark for the numerical scale, which might lead them to choose salient numbers or intermediate values.
… Monetary amounts provide interpersonally comparable references and thereby reduce the intrinsic subjectivity in pain measurements.
… The use of monetary incentives is unproblematic for those applications, as it is already common practice to reward participation in them"

I heard about this recently and I think it's brilliant. As the world is increasingly overwhelmed with (mostly bad, overblown) AI art and more, there's still a market of those who value integrity when it comes to their work. The Content Credentials website is entirely voluntary, but it shows those who are interested - in fairly detailed terms - what's been done to a digital creation - be it photography, music or whatever...
As an example, using Capture One 16.5to process a digital image, cut to about 1:02:10 in this video: https://www.youtube.com/live/-C73BzXdaqM?t=3728s
Capture One 16.5 has a checkbox to add this to the metadata on export.
More information on the Content Credentials website, here: https://contentcredentials.org/
P.S. I think AI art (well used) has validity, so long as one is clear on the origins and processes involved. Stealing people's work to train LLMs is an entirely different subject.

9/x Rebecca Jackson honed in on the problem of the meaning of measurement "units" in #SocialSciences.
Although not dissimilar to other areas of measurement, it is important to remember how many steps are necessary to establish that the units can be meaningfully interpreted.

CW: re: Unpopular philosophical opionion, subject related to a race theorist.
Philosophically, Validity is not a word that means worthwhile or dependable or anything like that.
Valid means that an argument progresses using the limited set of deductive inferences in a way that matches up.The transcendental argument does not follow the limited set of deductive inferences.
Hence it is very obviously invalid.
There's not such thing as a prerequisite in deduction.
There is no such thing as "possibility" in deduction.
Deduction outlines a world, and the world is populated by premise - very literally, the world contains that which is posited as premises, and only that.Possibility doesn't make any sense there, because a thing either is assumed (it is a premise) or it is not assumed (it is not a premise) or it is assumed-not (it is specifically assumed as absent in a premise).
The meaningless of possibility can be demonstrated:
If p is possible, this means that p or not-p, but p or not-p is always the case anyway.
It literally does not have a separate meaning.Deduction works with what follows.
If p then q.If you want to change the rules, and Kant did want to change the rules, then you are no longer in the realm of validity.
The reason why possibility is not a deductive property is that possibility is formed from our good ability to predict the world in general, juxtaposed with our poor ability to predict the world in detail.
These predictions are inherently inductive. They are incompatible with deduction (to be precise, induction is so much stronger than deduction that no inductive inventory is safe to use in deduction).

CW: Long thread: student evaluations are invalid and harm marginalized people but higher ed administrators cling to them like grim death
Because (IMO) public universities are about retention, since the cold war ended and states began to defund them. My school (one of the smaller SUNY campuses) received over 80% of its funding from the State of New York about 20-25 years ago. Now that figure is under 20%.
At the same time, American higher ed has crammed universities full of middle management. Presidents, provosts, deans, etc. dress and talk like finance bros (even when they're not men) despite almost always coming from a non-finance academic background. How do you make an athropology professor start wearing a suit, carrying a briefcase, and using Wall Street buzzwords? Tell her that's the only way to become an administrator and get them six figures a year.

CW: Long thread: student evaluations are invalid and harm marginalized people but higher ed administrators cling to them like grim death
Some higher ed administrators have--after much pressure and ugliness, almost always involving a strong labor #union--finally moved SEIs slightly away from faculty job security. However, most have not, and even those responding to #labor pressure have kept SEIs involved in faculty job decisions in some way. Presidents, provosts, deans, and--presumably--regents and trustees are really, *really* invested in having faculty employment depend on SEI scores.
Why?

CW: Long thread: student evaluations are invalid and harm marginalized people but higher ed administrators cling to them like grim death
Instructors who are more attractive, have tattoos, tell more jokes, and give little prizes in class get higher SEI scores, on average. And of course instructors who hand out high grades with little effort get consistently high scores.
Who gets lower scores? Instructors who
- Grade rigorously
- Have high learning standards
- Are Black, Hispanic, Native American, Asian, or otherwise not White
- Are (apparently) gay, bi, trans, or have any other apparent LGBTQIA+ identity
- Have an accent
- Look stern
- Are old (note: this might interact with gender and academic field)6/

CW: Long thread: student evaluations are invalid and harm marginalized people but higher ed administrators cling to them like grim death
So what factors do predict scores? Student grades. Lower grades = lower SEI scores. Higher grades = higher SEI scores. And the students with the lowest grades + SEI ratings are more likely to actually fill these surveys out.
How to get higher SEI scores if you're a #highered instructor?
1. Give easy grades
2. Don't challenge the students
3. Bribe students (with cookies, free points, etc.)
4. Have tattoos
5. Smile a lot
6. Don't be a minority of any kind
7. Or a woman (this may depend on the academic field)5/

CW: Long thread: student evaluations are invalid and harm marginalized people but higher ed administrators cling to them like grim death
SEIs provide no information at all about the quality of a course or the amount the student learned. Not even if you think really hard about them. Not even if you slice the data a special way.
Of course, "invalid" really means "not valid for the stated goal." It means the measure doesn't measure what it says it measures.
What do SEIs measure? Apparently, things like "Student mood when filling out the survey" and possibly "how angry is the student."

CW: Long thread: student evaluations are invalid and harm marginalized people but higher ed administrators cling to them like grim death
In fact, the best empirical research finds that SEIs *are* slightly valid... in the opposite direction: higher SEI averages mean students learned *less*, overall.
There are dozens (possibly hundreds) of high-quality studies showing these things are invalid. Not "kind of valid," not "Pretty sure I can tease out some useful information;" INVALID. That's a strong statement and it can't be made often about something like this, but in this case it's easy to support.
