The specificity problem

Picture of a lancelet

Henry Shevlin has an interesting paper from 2021 in Mind & Language that just went open access: Non-human consciousness and the specificity problem: A modest theoretical proposal. Shevlin discusses the problem of applying cognitive theories of consciousness, developed within the context of human psychology, to non-human systems, such as animals or artificial systems. For example, … Continue reading The specificity problem →

An exercise in detection

I had to watch this several times before I saw it, so don't be discouraged if you don't the first time. If you're having trouble, it auto-replays at the original TikTok. https://twitter.com/social_brains/status/1518786027288104960 When you do see it, assuming you didn't initially, what were you conscious of before you caught it? Does it make sense to … Continue reading An exercise in detection →

How much can we change the causality of the brain and keep consciousness?

James of Seattle clued me in to a thought experiment described by Dr. Anna Schapiro in a Twitter thread. https://twitter.com/AnnaSchapiro/status/1512866137809195011 It's very similar to one discussed in a new preprint paper: Do action potentials cause consciousness? Like all good thought experiments, it exercises and challenges our intuitions. In this case, it forces us to contemplate … Continue reading How much can we change the causality of the brain and keep consciousness? →

The benefits of functionalism for animal welfare

Last week, Science News had an article about the difficulty of studying animal emotions, on understanding what an animal in a particular situation is really feeling. It's an interesting article, although not one with much new information for many of you. However, I want to focus on one point raised by one of the researchers … Continue reading The benefits of functionalism for animal welfare →

Decoded: How does a quantum computer work?

This Scientific American video, shared by Aeon, is pretty good if you're looking for a quick basic primer on quantum computing. It's short, less than nine minutes. Although I do have a beef which I'll discuss below. https://www.youtube.com/watch?v=uLnGp1WTNFQ Decoded: How Does a Quantum Computer Work? The beef, which is pretty common with popular explanations of … Continue reading Decoded: How does a quantum computer work? →

Complex life may be more rare in the universe than we thought

Image of the sun

Quanta has a pretty interesting article up today: A Solution to the Faint-Sun Paradox Reveals a Narrow Window for Life. Our understanding of the physics of the sun indicate that it should have been only 70% as bright as it is today. But if so, early Earth should have been a snowball not really capable … Continue reading Complex life may be more rare in the universe than we thought →
