162 | Leidy Klotz on Our Resistance to Subtractive Change

There is no general theory of problem-solving, or even a reliable set of principles that will usually work. It's therefore interesting to see how our brains actually go about solving problems. Here's an interesting feature that you might not have guessed: when faced with an imperfect situation, our first move to improve it tends to involve adding new elements, rather than taking away. We are, in general, resistant to subtractive change. Leidy Klotz is an engineer and designer who has worked with psychologists and neuroscientists to study this phenomenon. We talk about how our relative blindness to subtractive possibilities manifests itself, and what lessons might be for design more generally.

244 | Katie Elliott on Metaphysics, Chance, and Explanation

Is metaphysics like physics, but cooler? Or is it a relic of an outdated, pre-empirical way of thinking about the world? Closer to the former than the latter. Rather than building specific quantitativ...

243 | Joseph Silk on Science on the Moon

The Earth's atmosphere is good for some things, like providing something to breathe. But it does get in the way of astronomers, who have been successful at launching orbiting telescopes into space. Bu...

242 | David Krakauer on Complexity, Agency, and Information

Complexity scientists have been able to make an impressive amount of progress despite the fact that there is not universal agreement about what "complexity" actually is. We know it when we see it, per...

240 | Andrew Pontzen on Simulations and the Universe

It's somewhat amazing that cosmology, the study of the universe as a whole, can make any progress at all. But it has, especially so in recent decades. Partly that's because nature has been kind to us ...

There is an image, especially in Western cultures, of the rugged, authentic, self-made individual choosing how to navigate the intricacies of the social world. But there is no mystical soul within us,...
