Greatness Cannot Be Planned
Why does modern life revolve around objectives? From how science is funded, to improving how children are educated — and nearly everything in-between — our society has become obsessed with a seductive illusion: that greatness results from doggedly measuring improvement in the relentless pursuit of an ambitious goal. In Why Greatness Cannot Be Planned—The Myth of…

Blink and you see it
“Blink and you see it“ Every few seconds, our visual world disappears behind a thin fold of skin that maintains the tear film on the corneal surface and, for more than a tenth of a second, blocks light from falling onto the retina. “Blink and you miss it” is a common idiom that captures how…

Humans rationally balance abstract world models
This work adds to a growing body of research showing that the brain arbitrates between approximate decision strategies. The current study extends these ideas from simple habits into usage of more sophisticated approximate predictive models, and demonstrates that individuals dynamically adapt these in response to the predictability of their environment. How do people model the…

Defining intelligence: Bridging the gap
“Defining intelligence: Bridging the gap between human and artificial perspectives“ Achieving a widely accepted definition of human intelligence has been challenging, a situation mirrored by the diverse definitions of artificial intelligence in computer science. By critically examining published definitions, highlighting both consistencies and inconsistencies, this paper proposes a refined nomenclature that harmonizes conceptualizations across the two disciplines.…

Is Ockham’s razor losing its edge?
Is Ockham’s razor losing its edge? New perspectives on the principle of model parsimony The preference for simple explanations, known as the parsimony principle, has long guided the development of scientific theories, hypotheses, and models. Yet recent years have seen a number of successes in employing highly complex models for scientific inquiry (e.g., for 3D…

Why probability probably doesn’t exist
(but it is useful to act like it does) David Spiegelhalter All of statistics and much of science depends on probability — an astonishing achievement, considering no one’s really sure what it is. In our everyday world, probability probably does not exist — but it is often useful to act as if it does.— David…

Explanation in Biology
The most recent publication from the series “Philisophy of Biology” is “Explanation in Biology“, available for free download at the site. The book introduces and elaborates scientific explanations in biology and the life sciences. Explanations are viewed as a “primary” objective of science – theyoffer deep understanding and knowledge of the world, as opposed to…

The unbearable slowness of being …
The unbearable slowness of being: Why do we live at 10 bits/s? This article is about the neural conundrum behind the slowness of human behavior. The information throughput of a human being is about 10 bits/s. In comparison, our sensory systems gather data at ∼109 bits/s. The stark contrast between these numbers remains unexplained and touches…

Bayesian Models of Cognition
“Bayesian Models of Cognition Reverse Engineering the Mind” is a new MIT-press Open Access book available for online reading. The definitive introduction to Bayesian cognitive science, written by pioneers of the field. How does human intelligence work, in engineering terms? How do our minds get so much from so little? Bayesian models of cognition provide…

Energy cost of computation: stochastic thermodynamics?
“Is stochastic thermodynamics the key to understanding the energy costs of computation?” The relationship between the thermodynamic and computational properties of physical systems has been a major theoretical interest since at least the 19th century. It has also become of increasing practical importance over the last half-century as the energetic cost of digital devices has…

Functional Trade-offs in Cognition
“Basic Functional Trade-offs in Cognition: An Integrative Framework” by Marco Del Giudice and Bernard J. Crespi, 2018. Trade-offs between advantageous but conflicting properties (e.g., speed vs. accuracy) are ubiquitous in cognition, but the relevant literature is conceptually fragmented, scattered across disciplines, and has not been organized in a coherent framework. This paper takes an initial step toward a general…

Will We Ever Have Conscious Machines?
The question of whether artificial beings or machines could become self-aware or conscious has been a philosophical question for centuries. The main problem is that self-awareness cannot be observed from an outside perspective and the distinction of being really self-aware or merely a clever imitation cannot be answered without access to knowledge about the mechanism’s…
