Was I fooled or wasn’t I?
“What Is the Name of This Book?-The Riddle of Dracula and Other Logical Puzzles, by Raymond M. Smullyan” My introduction to logic was at the age of six. It happened this way: On April 1, 1925, I was sick in bed with grippe, or f lu, or something. In the morning my brother Emile (ten…

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…

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…

ostracism across contexts
“Psychosocial and behavioural consequences of ostracism across contexts“ Ostracism (being ignored and excluded) thwarts basic psychological needs fundamental for human survival. As a painful experience, ostracism has various mental health, cognitive and behavioural consequences. In this Review, we outline the main psychosocial and behavioural consequences of ostracism and consider how these consequences might be unique…

Insight –> selection of ideas
“Insight and the selection of ideas” describes the mechanisms underlying Eureka heuristic, explained within an active inference framework. Perhaps it is no accident that insight moments accompany some of humanity’s most important discoveries in science, medicine, and art. Here we propose that feelings of insight play a central role in (heuristically) selecting an idea from…

The Edge of Sentience
“The Edge of Sentience: Risk and Precaution in Humans, Other Animals, and AI.” by Jonathan Birch Can octopuses feel pain and pleasure? What about crabs, shrimps, insects, or spiders? How do we tell whether a person unresponsive after severe brain injury might be suffering? When does a fetus in the womb start to have conscious experiences?…

On principles of emergent organization
Adam Rupe, James P. Crutchfield published “On principles of emergent organization“: After more than a century of concerted effort, physics still lacks basic principles of spontaneous self-organization. To appreciate why, we first state the problem, outline historical approaches, and survey the present state of the physics of self-organization. This frames the particular challenges arising from mathematical intractability and…

Fast walkers have higher IQ and larger brains than slow walkers.
These findings are from a 5-decade cohort study of 904 participants in New Zealand published in @JAMANetworkOpen which tested the hypothesis that slow gait speed reflects accelerated biological aging at midlife. Slow gait was associated with multiple indices of compromised structural brain integrity, including smaller total brain volume, global cortical thinning, and reduced total surface…

42 and 5
Today, 42 years ago, we had the great pleasure of discovering the reality of 5-fold crystals. On the morning of 8 April 1982, an image counter to the laws of nature appeared in Dan Shechtman’s electron microscope. In all solid matter, atoms were believed to be packed inside crystals in symmetrical patterns that were repeated…

Bayesian model: prior–cost
Sohna and Jazayeri discuss in “Validating model-based Bayesian integration using prior–cost metamers” the two competing views on how humans make decisions under uncertainty. Bayesian decision theory (BDT) posits that humans optimize their behavior by establishing and integrating internal models of past sensory experiences (priors) and decision outcomes (cost functions). An alternative hypothesis posits that decisions…

Representation of priors and decisions
The PLOS article by Marshall, Ruesseler, Hunt, O’Reilly “representation of priors and decisions in the human parietal cortex” discusses how both humans and animals actively sample the environment using their sensory organs, far from being passive recipients of sensory information. In rodents, active sampling processes include whisking and sniffing; in primates, the most important and…

Interoception and Active Inference for mental health
Interoception refers to the process by which the nervous system senses and integrates signals originating from within the body, providing a momentary mapping of the body’s internal landscape and its relationship to the outside world. Active inference is based on the premise that afferent sensory input to the brain is constantly shaped and modified by…

The Future of Artificial Intelligence by Melanie Mitchell
AI is all around us recognizing our faces in photos, transcribing our speech, constructing our news feeds, navigating our driving routes, answering our search queries, and much more. But rapidly improving AI is poised to play a much bigger role in all of our lives. In this lecture, AI expert Melanie Mitchell demystifies how current-day…

Wicked7 – looking for “Regenerative” solution
12 jul 2022, TedX@Athens. Christian Sarkar makes bold statements: Globalization has failed. Income inequality has exploded. COVID hasn’t disappeared yet. And War is at the gate. What can be done in your neighborhood, in your city? We learn the lessons of regeneration from Palermo, Sicily – and the (website and) book by Christian Sarkar, Philip…
