New paper out on the Perceived Stress Scale! The PSS is a very commonly (mis)used measure, and our analysis clearly shows the need for changing how it is used.

#openaccess #openscience #opendata #psychometrics #rasch #measurement #stress

First, only the negative items actually assess stress and work together as a unidimensional scale. This means a shorter scale, 7 items from the PSS-14 (6 items from PSS-10).

Riddle:

My job is simple: measuring
Without a ticking gear or spring
Twenty-four portions of the day.
I have a narrow passageway
Through which the moments slowly trickle.
I’m often paired with scythe or sickle
To indicate there’s no suspension
Of movement through the fourth dimension.

What am I?

"If something can be observed, it can be measured."

The summer break is over and book notes are back. This time it's How to Measure Anything: Finding the Value of “Intangibles” in Business by Douglas W. Hubbard.

Even though the book goes into some measurement methods, the most value comes from providing frameworks on how to think about measurement and how it relates to decision making. The book is dense with info, but highly recommended.

#CMSPaper 1231: It is commonly accepted that the #StandardModel is an effective theory, meaning it stops working at high energy. This #measurement uses #topquarks to test a pragmatic extension to the standard model, called standard model effective field theory (#SMEFT) assuming that more complex interactions are possible and each will change the behavior of existing particles like top quarks. And those changes can be checked (which is what this paper does)

Does #curiosity refer to just one thing?

There seem to be two (related) notions:

Curiosity1: goal-directed information seeking — e.g., following a string of citations to find the source of a particular claim.

Curiosity2: exploratory information seeking — e.g., watching whatever explainer video is recommended next, even if it’s about a different question or topic.

Today I learned that pounds are, in fact, a measure of mass. Pound as a measure of weight, as distinct from mass, or pound-force, is defined as one pound-mass times standard acceleration due to gravity.

That's one less thing for me to be pedantic about. Sorry, make that one thing fewer. (Dangling prepositions aren't actually erroneous; just a violation of popular style guides.)

#measurement #weight #mass

Some pretty obvious and standard things are described here as novelties:

https://www.linkedin.com/pulse/re-wilding-leadership-seven-threads-rich-watkins?trk=news-guest_share-article

Basically:

1️⃣ #Leaders exist because they have #Followers,
2️⃣ Leaders are here to provide #Guidance within the #Regulation and #Control “hierarchy”
3️⃣ All #Measurement is personal and beneficial only to the measurer
4️⃣ The “hated” #Matrix organizations are connecting silos
5️⃣ Removing what is #NOT determines what IS #Possibile (the cone of possibilities)
6️⃣ Groups of people will form #Living systems that cannot be engineered but can only be maintained as a “garden”
7️⃣ #Negative feedback is the only useful #feedback. A “pat on the back” never helped anyone. 😀

Also, this is all set backward:

How can we ensure there are useful leadership Artefacts (tools, processes) and leadership Heuristics (rules of thumb, ways of doing things) - as well as Skills, Experiences and (of course) Natural talent.

I understand that as a consultant you have the “urge” to sell something tangible (a product) but you always have to start with the #People and their experience, skills, and natural talent, then identify the #Processes, what they do, and how are they connected (collaborate). Selecting the #Products (tools, SW, forms, space, facilities) that will support that is the last and the least important thing.

Btw, a process is not an #artifact (product). Only the “rule book” that describes the process is, and there is a huge difference between the two.

Another very interesting passage showing a deep understanding and appreciation of Pattee’s work:

This is how the two processes that necessitate symbolic description connect in Pattee’s theory: the biological function of #measurement is to #control. Living organisms are able to form many kinds of such measurement–control networks. The outcome of the measurement process may feed directly into the control network (as in tropisms). But, according to Pattee, for control to be displaced in space and time (e.g., delayed with respect to measurement), a symbolic coding must exist. The two processes of measurement and control fulfill the difficult ‘‘cementing’’ role between the #symbolic and the #dynamic, the discrete and the continuous, the static and the time-dependent. Even though the measurement process may be a dynamical one, its function, according to Pattee, cannot usefully be described by the same dynamics it is measuring. It is only in this sense that dynamics and symbols (the informational record of a measurement) are irreconcilable’’ or complementary

Pain is a subjective experience that varies from person to person and from situation to situation. This makes it hard to measure and treat effectively. Researchers seek ways to quantify pain using biomarkers, brain scans, and artificial intelligence. These methods could help improve pain management and diagnosis, as well as reduce bias and stigma.

Being too #measurement oriented in process, #product, people compromises the genuine improvement of what matters.

As W. Edwards Deming said, "The most important things cannot be measured." I believe this is true.

By focusing on what is measurable, you give the illusion of importance to things that are not the most important.

This counterintuitively severely limits your ability to manage what truly matters for success.

Discernible CEO @Wednesday shares her thoughts on where AI can be most valuable for strategic communications.

Spoiler: it's not in generating content.

"I believe there is a lot of promise for AI in making it easier and more cost-effective for organizations to adopt an outcomes-based approach to measurement instead of merely counting outputs. Imagine, for example, that we could use AI to quickly and more expansively track the impact of the specific content, language, and timing of incident response communications.

Could we finally convince business leaders and lawyers that “your security is our top priority,” undermines the credibility of everything they’re about to say? What about whether specific characteristics of an incident are likely to impact a company's stock price or political climate? What kinds of engineering projects will be the most compelling for recruits over the next six months and do we already have a robust library of public content to attract them? We understand a lot of these considerations today based on qualitative research and measurement — which are invaluable for understanding the expectations of our stakeholders — but quantitative measurement is an area where I believe AI could help improve the effectiveness of our counsel."

@ByrdNick Relatable to "real life" (whose?) is good, but I think logically balanced is a better rubric.

A couple examples: these tests operate with internal contradiction in design. What's the 'correct' answer? If you don't have that worked out yourself, on what basis are you measuring "#morals"? (the extra judgement on cognitive vs emotional #empathy at the end)

To me, this is pretty self-evident considering the ND's (#ASD) higher stress from the test, while rating their decision as correct.

Heightened #rationality exaggerates the awareness of the test-as-context (rather than the presented situation), and #biases toward the narrower, 'as is' interpretation.

By increasing the bet, or adding the variable of higher/lower "value" to those being sacrificed for the greater good, the context changes considerably, and external factors such as training for roles, and #expectations show significant response variation.

See: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7987167/

IMO (& experience), NDs are much more likely to consider external factors, including previous #tests, and the fact that "tricks" are a common tactic in them, combined with their roles as students who are expected to give "the right answer", which may not be the most immediately obvious or palatable one.

Perhaps the most famously weird feature of #quantum mechanics is nonlocality.

Measure one particle in an entangled pair whose partner is miles away, and the measurement seems to rip through the intervening space to instantaneously affect its partner.

This “spooky action at a distance” (as Albert #Einstein called it) has been the main focus of tests of quantum theory.
