Welcome to the March 2022 Ask Me Anything episode of Mindscape! These monthly excursions are funded by Patreon supporters (who are also the ones asking the questions). I take the large number of questions asked by Patreons, whittle them down to a more manageable size — based primarily on whether I have anything interesting to say about them, not whether the questions themselves are good — and sometimes group them together if they are about a similar topic.

If extraterrestrial life is out there — not just microbial slime, but big, complex, macroscopic organisms — what will they be like? Movies have trained us to think that they won’t be that different at all; they’ll even drink and play music at the same cafes that humans frequent. A bit of imagination, however, makes us wonder whether they won’t be completely alien — we have zero data about what extraterrestrial biology could be like, so it makes sense to keep an open mind. Arik Kershenbaum argues for a judicious middle ground. He points to constraints from physics and chemistry, as well as the tendency of evolution to converge toward successful designs, as reasons to think that biologically complex aliens won’t be utterly different from us after all.Support Mindscape on Patreon.Arik Kershenbaum received his Ph.D. in Evolutionary Biology and Ecology from the University of Haifa.

We’re pretty well-calibrated when it comes to dealing with common, everyday-level setbacks. But our brains aren’t naturally equipped for dealing with unlikely but world-catastrophic disasters. Yet such threats are real, both natural and human-induced. We need to collectively get better at anticipating and preparing for them, at the level of political action.

Advances in technology have gradually been extending the human self beyond its biological extent, as we augment who we are with a variety of interconnected devices. There are obvious benefits to this — it lets us text our friends, listen to podcasts, and not get lost in strange cities. But as it changes how we interact with other people, it’s important to consider the possible downsides. Sherry Turkle is a psychologist and writer who specializes in the relationship between humans and their technology. She makes the case for not forgetting about empathy, conversation, and even the occasional imperfection in how we present ourselves to the world.Support Mindscape on Patreon.Sherry Turkle received her Ph.D. in sociology and personality psychology from Harvard University.

One of the brilliant achievements of Darwin’s theory of natural selection was to help explain apparently “purposeful” or “designed” aspects of biology in a purely mechanistic theory of unguided evolution. Features are good if they help organisms survive. But should we put organisms at the center of our attention, or the genetic information that governs those features? Arvid Ågren helps us understand the attraction of the “selfish gene” view of evolution, as well as its shortcomings. This biological excursion has deep connections to philosophical issues of levels and emergence.Support Mindscape on Patreon.Arvid Ågren received his Ph.D. in Ecology and Evolutionary Biology from the University of Toronto.

Artificial intelligence is everywhere around us. Deep-learning algorithms are used to classify images, suggest songs to us, and even to drive cars. But the quest to build truly “human” artificial intelligence is still coming up short. Gary Marcus argues that this is not an accident: the features that make neural networks so powerful also prevent them from developing a robust common-sense view of the world. He advocates combining these techniques with a more symbolic approach to constructing AI algorithms.Support Mindscape on Patreon.Gary Marcus received his Ph.D. in cognitive science from MIT.

Modern particle physics is a victim of its own success. We have extremely good theories — so good that it’s hard to know exactly how to move beyond them, since they agree with all the experiments. Yet, there are strong indications from theoretical considerations and cosmological data that we need to do better. But the leading contenders, especially supersymmetry, haven’t yet shown up in our experiments, leading some to wonder whether anthropic selection is a better answer. Michael Dine gives us an expert’s survey of the current situation, with pointers to what might come next.Support Mindscape on Patreon.Michael Dine received his Ph.D. in physics from Yale University.

Reality is just out there — but how we perceive reality and talk about it depends on choices we human beings make. We decide (consciously or not) to conceptualize the world in certain ways, whether it’s because those ways provide elegant predictive descriptions or because they serve a more subtle political purpose. To get at the true nature of reality, therefore, it’s important to think about which aspects of it are socially constructed, and why. I talk with Sally Haslanger about these issues, and the techniques we can use to understand the world and make it a better place.Update (22 March): Our discussion here could have (and did) leave some listeners with the wrong impression of how Sally and I feel about trans rights -- we are entirely for them! My fault for not making things more clear during the conversation. So I have added a brief note during the podcast intro to make our position perfectly explicit.

A good story takes you on an emotional journey, with ups and downs along the way. Thanks to science, we can quantify that. Peter Dodds works on understanding the structure of stories and other strings of words (including Twitter) by analyzing the valence of individual words, then studying how they are strung together in different kinds of stories. Understanding these structures offers powerful insight into how people communicate and how to reach them. As Peter says, “Never bring statistics to a story fight.”Support Mindscape on Patreon.Peter Dodds received his Ph.D. in mathematics from the Massachusetts Institute of Technology.
