Introducing “Pretend Battleship”: you’re told where all the ships are but then have to play like you never got that information. Could you do it? And what would your performance reveal about your understanding of your own mind? A joy to be part of this creative project led by @matanmazor.bsky.social
Very happy to see "Pretending not to know reveals a capacity for model-based self-simulation", a collaboration with @chazfirestone.bsky.social and @ianbphillips.bsky.social, out in Psych. Science!

❤️ the best news!! For Jorge, Duke, and the field as a whole. Jorge & his work are absolutely incredible, not least because he sets an example for the rest of us of how to do deep & impactful work across disciplines. Jealous of Duke phil+psych+neuro community for scoring such an excellent colleague!!
I have news! After 4 fabulous years at Northeastern, this July I will be moving to Duke—with tenure! It’s hard to convey how grateful I am to everyone who has made this possible: from old professors in Mexico and mentors in the US to students, colleagues, and, of course, my amazing wife and family.

this reminds me that I should tell Jeremy Goodman that he was right and I was wrong about this, I tried to work on it for a while and the common knowledge case does create a ton of complications that don't arise for K-omega

Now out in @science.org: @chazfirestone.bsky.social and I review Steven Pinker's new book "When Everyone Knows that Everyone Knows...". We learned a ton from it, but think its central thesis—that common knowledge explains coordination—faces a powerful challenge. 🧵

Love this work by @dillonplunkett.bsky.social and @jorge-morales.bsky.social! Representational momentum beyond motion 👇
When we see something that's moving, our memories about it end up projected forward in time: We remember it further along than it was. In a new paper in 𝘗𝘴𝘺𝘤𝘩𝘰𝘭𝘰𝘨𝘪𝘤𝘢𝘭 𝘚𝘤𝘪𝘦𝘯𝘤𝘦, out today and led by @dillonplunkett.bsky.social, we demonstrate that this happens even when there is 𝙣𝙤 𝙢𝙤𝙩𝙞𝙤𝙣 𝙬𝙝𝙖𝙩𝙨𝙤𝙚𝙫𝙚𝙧.🧵
