Response to quibbles: So, deferring to the powerful and popular is your plan for becoming a man? You are cutting through to the decent human being hiding in the confused lunkhead.

Core message: All you have to say, but you do have to say it, is "dude, cut that out." If you are feeling a little brave, you could say "miss, are you alright?" You have to say it right in the moment.

Situational opening: Passers-by. Graduate students. _Swedes_. How did that make you feel? Possibly too gentle, and you have to write it. Suggests you have thought about specifics. Also 100% instant comprehension.

Evergreen opening: The University should admit some men. Boys aren't working out. Possibly too blunt, but you are trying to cut through to a confused lunkhead. 100% instant comprehension in my experience.

As LLMs become increasingly important, we're seeing experiments that explore their behavior. (I expect Susan Calvin, Asimov's fictional robopsychologist from the1950 collection I Robot, will soon have scientists following in her footsteps.) #econsky marketdesigner.blogspot.com/2026/09/expe...

I understood how successful these ghouls would be when far, far too many smart and thoughtful people mired themselves in semantics about the plagiarism accusations against Claudine Gay. Arguing with known bad faith actors (and a love for minutiae) gave them the ultimate playbook.

I’ve always thought it was too bad that the Game Theory Society gave ownership of GEB to Academic Press when it was founded as opposed to retaining ownership themselves. The fact that it and the JET belonged to commercial publishers the main reason we started Theoretical Economics.

🚨Elsevier forces out Games and Economic Behavior (GEB) Editor, entire editorial board has resigned, current board only handling new submissions until Nov. 14 #econsky
    Dear Advisory Editor of GEB
    We are very sorry to be the bearers of bad news for GEB.
I learned from Elsevier on Wednesday July 28 that, contrary to my expressed willingness to continue, my 3-year contract will not be renewed.
    "Moving towards a closer alignment with Elsevier strategic priorities and publishing policies" was offered as the motive for this decision. Requests for explanations, first by me, then in a collective letter by the other six Editors, were dismissed by Elsevier which simply reaffirmed its legal power to make such decisions.
    Elsevier then started precipitously its own search for new Editors without input of the Editorial Board.
    By Friday August 14 all seven Editors have sent their resignation, requiring a 3-month advance notice.
    Therefore, we will continue to manage as before the papers currently under review and the new submissions until Saturday November 14. After this date we will only complete the evaluation of papers still waiting an editorial decision.
