Paradox of Predictability
“The paradox of predictability provides a bridge between micro- and macroevolution” The relationship between the evolutionary dynamics observed in contemporary populations (microevolution) and evolution on timescales of millions of years (macroevolution) has been a topic of considerable debate. Historically, this debate centers on inconsistencies between microevolutionary processes and macroevolutionary patterns. Here, we characterize a striking…

The Universe Learning Itself
“The Universe Learning Itself: On the Evolution of Dynamics from theBig Bang to Machine Intelligence” We develop a unified, dynamical-systems narrative of the universe that traces a continuous chain of structure formation from the Big Bang to contemporary human societies and their artificial learning systems. Rather than treating cosmology, astrophysics, geophysics, biology, cognition, and machine…

Decoding the architecture of living systems
“Decoding the architecture of living systems“, by Manlio De Domenico The possibility that evolutionary forces — together with a few fundamental factors such as thermodynamic constraints, specific computational features enabling information processing, and ecological processes — might constrain the logic of living systems is tantalizing. However, it is often overlooked that any practical implementation of…

Mapping interactions between adversity and neuroplasticity across development
“Mapping interactions between adversity and neuroplasticity across development” Highlights: We propose a theoretical framework to formalize major ways in which experience (particularly adversity) interacts with neuroplasticity during human development. Adversity can uniquely influence neural circuitry depending on the state of neuroplasticity during the developmental timing of exposure (i.e., neuroplasticity as a moderator). Neuroplasticity is itself…

Statistics is not measurement
“Statistics is not measurement: The inbuilt semantics of psychometric scales and language-based models obscures crucial epistemic differences” This article provides a comprehensive critique of psychology’s overreliance on statistical modelling at the expense of epistemologically grounded measurement processes. It highlights that statistics deals with structural relations in data regardless of what these data represent, whereas measurement…

Why collective behavioursself-organize to criticality
“Why collective behaviours self-organize to criticality: a primer on information-theoretic and thermodynamic utility measures” Collective behaviours are frequently observed to self‑organize to criticality. Existing proposals to explain these phenomena are fragmented across disciplines and only partially answer the question. This primer compares the underlying, intrinsic, utilities that may explain the self‑organization of collective behaviours near…

The ‘made-up mind’.
“The ‘made-up mind’. Deriving new hypotheses on delusions from general psychological models of belief maintenance” Highlights Delusions may be maintained by changed external input and prediction error processing. Perceived belief utility and high accordance with related beliefs favor maintenance. Systematized delusions may result from deriving auxiliary hypotheses or latent causes. How well conflicting evidence is…

Social networks affect redistribution decisions and polarization
“Social networks affect redistribution decisions and polarization” “Whom you observe in your daily life alters your willingness to tax the rich” Recent research suggests that the visibility of extreme wealth within a person’s social circle drives their support for economic redistribution but simultaneously fosters political polarization and personal dissatisfaction. A study published in PNAS Nexus combines computational…

“Putting nature on the balance sheet: how to account for the ecological costs of our actions” Economists should consider forests and wetlands as well as factories and farms. A book review of “On Natural Capital: The Value of the World Around Us“, Partha Dasgupta (2025) On Natural Capital recaps the roaring economic advances of the past 75…

The immorality of too much money
“The immorality of too much money” Study across 20 countries shows extreme wealth seen as more immoral in richer, equal societies — tied to moral purity beliefs. “Filthy rich” takes new meaning. In Fast Company: ow.ly/zJBe50XsSWx In PNAS Nexus: ow.ly/JyJ950XsSWy In some societies, people find excessive wealth immoral, while others are structured so that having…

Stubborn Goals: the adaptive value
“The adaptive value of stubborn goals” Humans show strong attachment to goals they have selected. While often framed as a maladaptive bias, we outline three adaptive functions leading to stable goals: efficient cognitive resource allocation, shielding from interference, and scaffolding motivation in the absence of immediate and tangible reward signals. These considerations shape the algorithmic…

Blocking of associative learning by explicit descriptions
“Blocking of associative learning by explicit descriptions” People given written descriptions often learn and decide differently from those learning from experience, even in formally identical tasks. This paper presents two experiments detailing how telling participants about the value of one stimulus impacts a keystone learning effect – blocking. The paper investigates if descriptions can be…
