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 exhibit a striking tendency to persist with chosen goals. This strong attachment to goals can often appear irrational – a perspective captured by terms such as perseverance or sunk-cost biases. In this review, we explore how goal commitment could stem from several adaptive mechanisms, including those that optimise…

Decisions: Studying and Supporting
“Decisions: Studying and Supporting People Facing Hard Choices“ A lively, authoritative insider’s account of how we make decisions and how decision-making research has developed over the last half century. Decisions describes the evolution of decision science (also called behavioral decision research and related to behavioral economics) through its application to challenging personal and public policy decisions,…

Harmony in the brain
“Harmony in the brain: A narrative review on the shared neural substrates of emotion regulation and creativity” The contribution of creativity in overall well-being through regulating emotions has sparkled research interest in employing artistic interventions recently for the improvement of mental health. Although the behavioural links between emotion regulation and creativity have been established, the neural networks reflecting…

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…

“The fault, dear Brutus, is not in our stars, but in ourselves” William Shakespeare Dear Friends and Fellow Humans, I turn 70 today. For 7 decades I’ve had the privilege of living out my childhood dream, which was simply to UNDERSTAND. After spending more than half a century meeting people from all over the world…

End GDP mania
“End GDP mania: how the world should really measure prosperity” Last week’s United Nations General Assembly, held in New York City, generated no shortage of headlines. But one notable policy initiative from the world body was not discussed by world leaders when it should have been. UN secretary-general António Guterres has put together a high-level…

Fast, slow, & metacognitive
“Fast, slow, and metacognitive thinking in AI” Inspired by the ”thinking fast and slow” cognitive theory of human decision making, we propose a multi-agent cognitive architecture (SOFAI) that is based on ”fast”/”slow” solvers and a metacognitive module. We then present experimental results on the behavior of an instance of this architecture for AI systems that…

From Soundwaves to Brainwaves: “Music”
“From Soundwaves to Brainwaves: The Transformative Power of Music” The human brain physically embodies rhythmic sound in a remarkablesymphony that has the power to heal. People resonate to music. They respond positively in ways that suggest that the rhythms of the brain and body, like neurons, breathing, or cardiac rhythms, are engaged when you listen…

Critical Thinking for Medicine—Moving Beyond Illness Scripts
“Critical Thinking for 21st-CenturyMedicine—Moving Beyond Illness Scripts” Clinical Reasoning for 21st-Century Medicine: Optimal clinical reasoning will involve an appropriate balance betweenillness scripts and pathophysiological reasoning. In our view, medical education has historically overemphasized the former—to which learners are predisposed even without explicit teaching— and underemphasized the latter. The risks of this historical approach will become…

Computational Framework for cognitive biology
“Toward a computational framework for cognitive biology: Unifying approaches from cognitive neuroscience and comparative cognition” Progress in understanding cognition requires a quantitative, theoretical framework, grounded in the other natural sciences and able to bridge between implementational, algorithmic and computational levels of explanation. This review article reviews recent results in neuroscience and cognitive biology that, when combined, provide key components…

Brain-body physiology
“Brain-body physiology: Local, reflex, and central communication” Behavior is tightly synchronized with bodily physiology. Internal needs from the body drive behavior selection, while optimal behavior performance requires a coordinated physiological response. Internal state is dynamically represented by the nervous system to influence mood and emotion, and body-brain signals also direct responses to external sensory cues,…

Divergent Perception: Framing Creative Cognition
“Divergent Perception: Framing Creative Cognition Through the Lens of Sensory Flexibility” “Savoir regarder est un moyen d’inventer.” Salvador Dali. Creativity is a cornerstone of human evolution and is typically defined as the multifaceted ability to produce novel and useful artifacts. Although much research has focused on divergent thinking, growing evidence underscores the importance of perceptual…

Towards embodied intelligence
“Intelligent soft matter: towards embodied intelligence” Intelligent soft matter lies at the intersection of materials science, physics, and cognitive science, promising to change how we design and interact with materials. This transformative field aims to create materials with life-like capabilities, such as perception, learning, memory, and adaptive behavior. Unlike traditional materials, which typically perform static…

Known and Unknown Biases
“Known and Unknown Biases: A Framework for Contextualising and Identifying Bias in Animal Behaviour Research“ (This article discusses the bias in animal behaviour research, but – as known to most readers, I hope – humanes too are members of the animal kingdom 🙂 Biases in animal behaviour research are inevitable consequences of our societal and…

A Model of Creative Thinking
“Adaptive Decision-Making “Fast” and “Slow”: A Model of Creative Thinking” The late Daniel Kahneman introduced the concept of fast and slow thinking, representing two distinct cognitive systems involved in decision-making (DM). Fast thinking (System 1) operates intuitively and spontaneously. In contrast, slow thinking (System 2) is characterized by deliberation and analytical reasoning. Following Kahneman’s view, called the…

Climate Change, A Geoscience Perspective
Climate Change, A Geoscience Perspective This open access book on climate change assesses past climatic change from a geoscience perspective and directly and effectively addresses common misconceptions on climate and climate change. A geoscience perspective on the multiple causes, rates, and consequences of climate change is essential context to assess modern climate change and our…
