Human innovation depends on our collective brains
A recent study investigates hunters’ causal understandings of bow design and mechanics among the Hadza, one of the last remaining foraging populations. The results suggest that sophisticated technology can evolve without complete causal understanding. Human innovation depends not on our individual brainpower but on our collective brains, on networks of diverse minds sharing information, lucky…

How Occam’s razor guides human decision-making
A rather complex but very interesting article was published @PennLibraries and (somewhat more recent) @bioRXiv But for those who want to understand by a lecture, I can recommend the Simons Faoundation lecture from Joshua Gold (also available on Youtube: How Occam’s Razor Guides Human and Machine Decision-Making) Occam’s razor is the principle stating that, all…

Brain-Behavior relationships
“Improving the study of brain-behavior relationships by revisiting basic assumptions” discusses how scientific communities tacitly agree on assumptions about what exists (called ontological commitments), what questions to ask, and what methods to use. All assumptions are firmly rooted in a philosophy of science that need not be acknowledged or discussed but is practiced nonetheless. In…

“Average is good, extremes are bad”
Traditionally, studies emphasize differences in neural measures between pathological and healthy groups, assuming a binary distinction between the groups, and a linear relationship between neural measures and symptoms. A continuous relation across the divide of normal and pathological states between neural measures and mental functions shows a relation which can be characterized by a nonlinear…

Intellectual humility
Intellectual humility involves recognizing that there are gaps in one’s knowledge and that one’s current beliefs might be incorrect. For instance, someone might think that it is raining, but acknowledge that they have not looked outside to check and that the sun might be shining. Research on intellectual humility offers an intriguing avenue to safeguard…

Language influences perception and concept formation
A neurobiologically constrained model of semantic learning in the human brain was used to simulate the acquisition of concrete and abstract concepts, either with or without verbal labels. Concept acquisition and semantic learning were simulated using Hebbian learning mechanisms. The network’s category learning performance is defined as the extent to which it successfully: (i) grouped…
