Cognitive offloading and its consequences

For thousands of years—maybe for as long as we've been human—we've offloaded our thinking. We've counted on our fingers. We've carved tallies into bone. We've invented a long series of tools to help us reason, remember, and manage information—tools like abacuses, calendars, writing systems, calculators, smartphones, and many, many more. So cognitive offloading is hardly new—but the questions around it seem newly urgent. As cognitive technologies accumulate, as opportunities for offloading tempt us at every turn, as headlines warn of "digital dementia" and "cognitive surrender," it seems like a good time to take stock. Yes, cognitive offloading can save us time and effort. But what are its other consequences?

My guest today is Dr. Sam Gilbert. Sam is a Professor of Cognitive Neuroscience at University College London. Sam and his colleagues have been trailblazers in the study of cognitive offloading—when we do it, why we do it, what it does for us and to us.

Here, Sam and I talk about what cognitive offloading is, how deep it goes in our species' history, and how it pervades our everyday lives. We talk about the different forms that offloading takes. We discuss why some people offload more than others, and why we offload in certain situations. We walk through three bodies of research on the consequences of cognitive offloading—research on the so-called Google effect, on the photo-taking impairment effect, and on the impact of using GPS to navigate. Of course, we also address the elephant in the room: How should we think about the possible dangers—and benefits—of cognitive offloading in the new era of AI?

Before we get to it, some news: We have re-launched the Many Minds newsletter, as a Substack! We'll be sharing each of our episodes there, as well as other morsels from time to time. We've been wanting to do this, in part, to give you a better way to engage with us—and with each other. Were there questions we should have asked? Are there connections you made that we didn't? Counterarguments we overlooked? Et cetera. All that stuff can now go in the comments for each episode. So, if you're a fan of the show, please do consider subscribing and following along with us there.

Alright friends, on to my conversation with Dr. Sam Gilbert. Enjoy!
