The LLM majors in America are often bad faith actors. The social consequences of mass compute, prediction, and function in many professional knowledge processing is serious. And some of the most prominent critics of this technology do not have the basic technical and academic familiarity with them.

GOOD NEWS! Researchers have discovered a new antibiotic, known as manikomycin, that may be a bulwark in the fight against drug-resistant superbugs. By attacking the ribosome in a never-before-seen way, manikomycin can evade the existing mechanisms pathogens have developed to resist antibiotics.

As a teenager in the mid-2010s who was around the math/physics/philosophy community (was broadly in social science + philosophy of mathematics as a college student), the rationalist scene was weird as hell, man. A lot of good people in it! But also, a lot of people with obvious bad intentions.

Innumeracy and its consequences have been a disaster for society. There are trillions being poured into technology because it can perform certain functions! How they work and how they fail are incredibly important and fundamentally, much of the commentary about them *does not engage in that.*

annoyed this never occurred to me. (it's a method for bootstrapping repeated measures data. text via Deen & de Rooij, 2020, doi.org/10.3758/s134...)
Balanced bootstrap  The balanced bootstrap can be used to ensure that every individual appears exactly B times in the bootstrap samples, in contrast to randomly drawing bootstrap samples from the parent sample. Davison and Hinkley (1997) show that the balanced bootstrap results in an efficiency gain.  For unbalanced longitudinal data, where some subjects have more measurements than others, the balanced bootstrap ensures that the average size of the bootstrap samples equals the (subject) sample size N. In the balanced bootstrap, rather than simply drawing at random, a matrix is made with B copies of the numbers 1 to N. This matrix is vectorized, randomly shuffled, and turned back into a matrix of size N × B (Gleason, 1988). Each of the columns of this latter matrix gives the indices of a single bootstrap sample.

Let me be blunt, as a statistician who's worked in Natural Resources Management: Wild horses, especially in the American West, are an invasive non-native species that out-compete native foragers. In a water-starved West, they're accelerating soul erosion and declines in plant biomass.

I've spent a lot of my life struggling to accept the choices I made when I was disowned, kicked out, and homeless at 15. The things I chose to do to for housing, food, and an education. The way I behaved as a person. I saw a 15 year old in the clinic the other day. They looked so fucking young.

the always-insightful Christian Hellwig has a (recently posted) Chicago Fed working paper that looks provocative and interesting: www.chicagofed.org/publications...
screen shot of abstract with text:

The Inefficient Markets Hypothesis Theory of Casino Capitalism
Christian Hellwig



I develop a general equilibrium model of investment and equity markets in which departures from the Efficient Markets Hypothesis generate “Casino Capitalism”: time-inconsistent, short-termist firm decisions, firm-level over-investment coupled with inefficient liquidation of positive-NPV projects, and aggregate under-investment with depressed stock prices and distorted intertemporal savings. These distortions arise even if all agents are fully rational and forward-looking. At the firm level, the wedge between market-implied and fundamental returns on investment causes an endogenous preference reversal that renders the Laissez-faire outcome time-inconsistent and Pareto-inferior. In the aggregate, firm-level attempts to boost stock prices are self-defeating via an aggregate investment wedge as micro distortions translate into macro inefficiency. Restoring firm-level rationality by empowering shareholders can worsen aggregate outcomes and precipitate a complete capital market shutdown.

arXiv📈🤖 int3ract: Johnson-Neyman Technique and its Three-Way Extension for Frequentist and Bayesian Models in R By Krause
Interaction effects are ubiquitous in applied statistical modelling, yet their meaningful interpretation remains challenging. The classic Johnson-Neyman (JN) technique (Johnson and Neyman 1936) addresses this challenge for two-way interactions by identifying the regions of a moderator's range over which a focal effect is and is not statistically significant. The int3ract package for R implements the JN technique and its three-way extension (the Johnson-Neyman-Krause, or JNK, technique) for both frequentist and Bayesian models. The function JNK_freq() auto-detects models fitted via lm()/glm(), RSiena's siena(), or lme4's lmer()/glmer(), but can also be applied to multiplicative interactions from (virtually) any model family by supplying a coefficient vector and covariance matrix directly. For Bayesian Stochastic Actor-Oriented Models (SAOMs) estimated with multiSiena, or any model producing posterior draws, the function JNK_bayes() produces conditional posterior distributions. For two-way interactions, classic shaded confidence-band plots are created that visually demarcate significant and non-significant regions along the moderator range; three-way interactions yield colour-gradient heatmaps with optional crosshatch overlays for non-significant regions. The package is designed to encourage richer, region-specific reporting of interaction effects in place of the conventional single-slope spotlight approach. The package is currently available on Github 'RWKrause/int3ract'.

ABSTRACT

Spreadsheets are widely used software tools for data entry, storage, analysis, and visualization. Focusing on the data entry and storage aspects, this article offers practical recommendations for organizing spreadsheet data to reduce errors and ease later analyses. The basic principles are: be consistent, write dates like YYYY-MM-DD, do not leave any cells empty, put just one thing in a cell, organize the data as a single rectangle (with subjects as rows and variables as columns, and with a single header row), create a data dictionary, do not include calculations in the raw data files, do not use font color or highlighting as data, choose good names for things, make backups, use data validation to avoid data entry errors, and save the data in plain text files.

Is the only way we can create algorithms that people understand to make them trivially simple? We argue, no. People can predict the behavior of algorithms that are arbitrarily complex, if and only if they are available, compact and aligned. arxiv.org/abs/2601.18966
A search for factors for algorithm understanding results in multiple terms displayed as documents, including available, compact, and aligned. These are shown to be necessary and sufficient. Other, similar terms are shown in the background faded, like intuitive, rule-based, grounded, modular, linear, decomposable, accurate, symbolic, causal, and personalized.
