proudest achievement of the semester: made my first ever single page double sided handout that’s for a conference presentation

Now things are all settled: I’ll be a visiting student at the University of Southern California in Fall 2026, sponsored by the wonderful @dmitrigallow.bsky.social :) I’m super excited about this—friends in SoCal HMU!!

This semester, I taught an undergraduate course on Probability and Rational Choice for the first time. My lecture notes are here: jdmitrigallow.com/teaching/par...

Me putting on Roger White's universal persuasion machine, which makes you rationally have any arbitrary credence in any proposition (in this case, 'the ship is seaworthy').

my life in a nutshell

Actually just found a second one

Just wrapped up an absolutely dreamlike three-day-marathon at the Northeastern Epistemology Workshop and realized that I have taken only one (!) photo to capture the wonderful memory. Featured: @wiglet1981.bsky.social, Branden Fitelson, me, and me & Richard's scribbles.

when you’re over caffeinated and happen to do formal epistemology

Love: also systematic and productive

The official version is available online! It's open access. (And yes, it's in double column.) onlinelibrary.wiley.com/doi/10.1111/...

A grad student put up a bunch of these MIT philosophy themed valentines. I thought this one was fantastic and told them so. Turns out I came up with it a couple years ago and they had just parroted me. Perry’ed again

this is the weirdest valentine thing I've seen (it's MILDLY SWEET tho)

I'm excited to share that my first paper "Guessing and its Limits" is forthcoming in Philosophy and Phenomenological Research! Thread below. TLDR: I present a novel puzzle for a recent "question-sensitive" theory of guessing/belief in multi-question scenarios. philpapers.org/rec/FANGAI-2

Come to our session at the Eastern APA next week! @chenhao345.bsky.social will present an excellent solution to my puzzle about inter-question guessing (so-called "weak belief"); then @benholguin.bsky.social and I will respond. (AFAIK this is the first response in the literature!) Should be fun.

I’ve been harassing every single person I know over the past couple of months about this paper nonstop and now here’s an even better promotion

I know of some work vaguely in this direction (e.g., studies on how non-human primates don't learn language) but wanted to ask: does anyone know studies/literature on whether non-human animals ask questions? (My understanding is they don't but want to read the lit before I form a strong view.)

There’s more. She reviews “Steffan Yabble” here.

Happy to report that this paper is now out (Open Access!) onlinelibrary.wiley.com/doi/epdf/10....

writing my paper for my history course at harvard in the most mit way possible:

Everything I know about legal formalism I learned from It’s the Great Pumpkin, Charlie Brown.

or as Helena calls it "simple-modelogy"

As a formal epistemologist AND rhythm game nerd I just came to the realization that the two fields ARE THE SAME---both are about MAXIMIZING ACCURACY

Okay this is for next week

me: so i decided to write my fifth term paper on a cursed topic; guess which one my committee: de se belief me: not THAT cursed

Having so much fun making my advising meeting handouts

Pleased to announce that my paper, “Common Ground, Conditionals, and Ceteris Paribus Pragmatics,” is forthcoming in the Australasian Journal of Philosophy! 🧵

Happy to announce that my paper "How Language-Like is the Language of Thought?" is forthcoming at Ergo! Thread with a TL;DR below! philpapers.org/rec/MURHLI-3

New theory of deontic modality just dropped

Yale Philosophy offers a course on “Formal Philosophical Methods” — a broad introduction to probability, logic, formal semantics, etc. Instructor Calum McNamara has now made all materials for the course (78 pages) freely available static1.squarespace.com/static/6255f...

Last semester, I taught a graduate seminar on Bayesian epistemology. Here are my lecture notes: jdmitrigallow.com/teaching/epist25/aitbe.pdf

Four reasons why one should come to Iceland: 1. For my FEW 2. For @somayehtohidi.bsky.social 's amazing comments and epic table 3. For seeing a normal distribution in real life 4. For THE CLOCK (a marked one though)

increasingly convinced that philosophy is all about preorders

Did 3 presentations in 4 days consisting of (i) my first talk in a room full of strangers (ii) a prosem presentation where I made my handout in an hour and (iii) presenting for the epistemology reading group during prospective visits on a paper almost impossible to present. EXTREMELY proud of myself

Absolutely horrendous truth: I didn't know how to flip a coin. (Until was taught this morning.) I literally did not know. Even though all my papers are on coinflips rip

my second fav argument in philosophy: argument from elegance

@chenhao345.bsky.social : i think when ppl say 'might or might not p' they simply ARE conveying trivial information (hence triviality doesn't matter) Me: oops guess i should stop writing like that in my paper

am at a point where I simply hate partition sensitivity: it makes everything too easy that it makes everything too hard

everything in Knowledge and its Limits

Same thing almost made Lewis give up Humeanism

First two chapters of Inquiry *obviously*

Finally found my way here!
