1/9 Identification of "meaningful change" is a key area when working w patient-reported outcomes. Nevertheless, this seems to be another area of applied #psychometrics / #statistics where rituals may have replaced understanding & deliberate practice.

2/9 w QLR's special issue on "Methodologies & Considerations for Meaningful Change" (under #peerreview) we wanted to initiate a more deliberate approach, now rolled out to any paper submitted aiming to make a methodological contribution to this area👇

3/9 An area of concern are discussions around different indices, in particular for classifying intra-individual change: depending on interpretation/ use case, they are all likely not appropriate as they are based on between-indiv variation.
Progress is then not even incremental.

ERGODICITY AND THE TRAGEDY OF THE COMMONS
An example of tragedy of the commons. A city has access to a small forest.
If you are a citizen, self-interest would dictate that you cut a tree to get some wood to heat your house. But if everyone does, the wood disappears.

2/ The tweet below recently made me notice that this kind of problems can be formulated in terms of #ergodicity.
Let's see how and why it matters.

3/ One of the definitions of ergodicity is "when the outcome of a person performing an action n times coincides to the outcome of n people performing the action once."
Here is how it applies to the tragedy of the commons:

The idea is to make the concept as accessible at possible, so I won’t use any maths beyond 3rd grade, and will focus on examples not from investing but from everyone’s life.
Attendance is FREE even though it’s a Gumroad link.
It’s a Gumroad link because I offer a bundle “talk + book”, but if you want to just hear me the talk, you can register for free. I’m experimenting to see if this format is sustainable.

A nice example for #ergodicity in demography?
Inequality in life (literally!)
UK & US men life ~17yrs after retirement at 67
but US has 13.8% higher variability of age-at-death

Surprisingly, life expectancy is closely monitored, but life-span variation isn't

Double burden of inequality
Dying earlier + greater variation in time of death, whereby the latter is mostly dying much earlier than at life expectancy of your cohort, which is more pronounced in low socioeconomic groups.

Primer vuelo post-covid y 6 horas de retraso, así que para no volverme loco, voy a hacer algo nunca visto:
Voy a compartir mi bloc de notas de los últimos 4 años.
1 like = 1 idea, opinión o reflexión sobre inversión, negocios y la vida en general.
A ver hasta dónde llegamos 🛫

1. El dinero tiene una atracción metafísica hacia donde se cuida y se utiliza de manera correcta.
El papel de los mercados financieros es transferir dinero de empresas mediocres y de bajo rendimiento a empresas estables, con crecimiento y con buenos retornos.

John von Neumann's take on #ergodicity economics
In this thread I interpret JvN's prescient analysis on the development of mathematical economics (esp. decision theory) after his death

JvN directs the readers' attention to the danger if a mathematical discipline moves farther and farther away from its empirical source or any empirical content at all.
He qualifies this if that researchers with an "exceptionally well-developed taste" could make this a success.
He qualifies this if that researchers with an "exceptionally well-developed taste" could make this a success.
If the distancing from empirics happens, he predicts a fraying of the discipline "into a multitude of insignificant branches" and it "becomes a disorganized mass of details and complexities." Ultimately the discipline faces danger of degeneration due to "abstract inbreeding".
