A little while ago, my parents' cat Bridget went missing. As the weeks dragged on, they became extremely worried. My dad devised a way to distract himself: he began to paint Bridget's adventures, imagining her travelling through time and popping up in some of art and music's most iconic scenes.

I found this abstract I submitted (unsuccessfully) to a session on "cultural evolution in the digital age" for the first CES meeting in 2017. It's aged horribly well. Anyway, this is the kind of shit I'm increasingly trying to work on now.

Are We F*cked? Paul E. Smaldino, UC Merced The human population on earth and its impact on the environment, have hardly been stable. Since the industrial revolution, the size of the human population, its cultural complexity, and the magnitude of its environmental footprint have all grown tremendously. The advent of the digital age has fundamentally altered cultural dynamics and increased the potential for human activity at larger scales and faster paces. In light of our increased capacity to effect change, recent environmental catastrophes, such as the BP oil spill in the Gulf of Mexico and the bleaching of the Great Barrier Reef, coupled with the rise of quasi-dictators and xenophobic populism in the wealthiest and most heavily armed nations, should make us worried about the future of the nice civilization that affords conferences such as this one. I will review models and empirical results based in cultural evolutionary theory, which can give us insights into the kinds of dynamics that are currently unfolding, what we can expect, what we can do to improve things, and whether, in the end, we’re fucked.

Ever stared at a table of regression coefficients & wondered what you're doing with your life? Very excited to share this gentle introduction to another way of making sense of statistical models (w @vincentab.bsky.social) Preprint: doi.org/10.31234/osf... Website: j-rohrer.github.io/marginal-psy...

Models as Prediction Machines: How to Convert Confusing Coefficients into Clear Quantities Abstract Psychological researchers usually make sense of regression models by interpreting coefficient estimates directly. This works well enough for simple linear models, but is more challenging for more complex models with, for example, categorical variables, interactions, non-linearities, and hierarchical structures. Here, we introduce an alternative approach to making sense of statistical models. The central idea is to abstract away from the mechanics of estimation, and to treat models as “counterfactual prediction machines,” which are subsequently queried to estimate quantities and conduct tests that matter substantively. This workflow is model-agnostic; it can be applied in a consistent fashion to draw causal or descriptive inference from a wide range of models. We illustrate how to implement this workflow with the marginaleffects package, which supports over 100 different classes of models in R and Python, and present two worked examples. These examples show how the workflow can be applied across designs (e.g., observational study, randomized experiment) to answer different research questions (e.g., associations, causal effects, effect heterogeneity) while facing various challenges (e.g., controlling for confounders in a flexible manner, modelling ordinal outcomes, and interpreting non-linear models). Figure illustrating model predictions. On the X-axis the predictor, annual gross income in Euro. On the Y-axis the outcome, predicted life satisfaction. A solid line marks the curve of predictions on which individual data points are marked as model-implied outcomes at incomes of interest. Comparing two such predictions gives us a comparison. We can also fit a tangent to the line of predictions, which illustrates the slope at any given point of the curve. A figure illustrating various ways to include age as a predictor in a model. On the x-axis age (predictor), on the y-axis the outcome (model-implied importance of friends, including confidence intervals). Illustrated are 1. age as a categorical predictor, resultings in the predictions bouncing around a lot with wide confidence intervals 2. age as a linear predictor, which forces a straight line through the data points that has a very tight confidence band and 3. age splines, which lies somewhere in between as it smoothly follows the data but has more uncertainty than the straight line.

🚨Our paper `Reclaiming AI as a theoretical tool for cognitive science' is now forthcoming in the journal Computational Brain & Behaviour. (Preprint: osf.io/preprints/ps...) Below a thread summary 🧵1/n #metatheory #AGI #AIhype #cogsci #theoreticalpsych #criticalAIliteracy

The idea that human cognition is, or can be understood as, a form of computation is a useful conceptual tool for cognitive science. It was a foundational assumption during the birth of cognitive science as a multidisciplinary field, with Artificial Intelligence (AI) as one of its contributing fields. One conception of Al in this context is as a provider of computational tools (frameworks, concepts, formalisms, models, proofs, simulations, etc.) that support theory building in cognitive science. The contemporary field of Al, however, has taken the theoretical possibility of explaining human cognition as a form of computation to imply the practical feasibility of realising human(-like or -level) cognition in factual computational systems; and, the field frames this realisation as a short-term inevitability. Yet, as we formally prove herein, creating systems with human(-like or -level) cognition is intrinsically computationally intractable.

There’s plenty of eye popping numbers in this thread but this in the FT article really strikes: “When the base case is for 1,900 per cent revenue growth by 2028, isn’t it worth considering the risk of a shortfall?”

The crux of their argument is that if they're found liable, then the consequences of their own actions that no one forced them to take could ruin them and the rest of their industry that undertakes similar practices. To which I say motherfucker did you never hear about Napster

Likening PhD holders to a (non-functional) algorithm is a form of dehumanisation & anti-intellectualism that is a bellwether for contemporary fascism. Essentially it's a typical — if not the archetypal — first step towards fascism: to dehumanise, deskill, defund, and, ultimately, fire the academics.

I say this & I hate everybody who has a PhD mostly, primarily, & importantly: myself, BUT — lemme tell you! — killing us off is taking the cake. Let us live. We do pointless & useful stuff for a reason, knowledge production is valuable inherently. Without us: fascism. Give us a chance. 🥰

A lot of small birds take a bit of time splashing in shallow water when they bath. Not swallows. This barn swallow flew directly into the marsh at Mach 5, completely submerged for a second, and then exploded out in a shower of water drops to continue on its way! #Birds #photography #wildlife 🪶

A soaking wet barn swallow shows its bright rusty/ orange tummy as it explodes out of the water in a shower of water drops. They bath by flying into the water , submerging and then popping out and continuing on their flight!

An energy revolution is underway in this century, though it’s unfolded in ways slow enough and technical enough for most people not to notice (and I assume it’s nowhere near finished). It is astonishing – a powerful solution to the climate crisis... [Wrote it a while ago; came out yesterday.]

There’s an intersection with research on reading where there’s a suggestion that more accurate understanding of the information in text requires ‘active’ processing but text written to be easy to read can induces a feeling of understanding that reduces active questioning approaches to text

To return to the topic of the video then, I wonder if what @acollierastro.bsky.social is reacting to is the experience of having physics, for the first time in a long time, (fake) pulled by LLMs into that plain-language-breeds-contempt space that the humanities have been in for a long time.13/

But without an esoteric language in which a field must operate, the plain language works to conceal that and encourages the bystander to hold the field in contempt - @acollierastro.bsky.social hits this when she talks about how little value these folks had for art, until a machine could do it. 10/
