Yay for the editors of Journal of Philosophical Logic for collectively quitting Springer & starting something better!

And yay for @openlibhums for funding this new-but-venerable diamond #openaccess journal.

"All of the editors-in-chief and associate editors of Springer Nature’s Journal of Philosophical Logic have announced their immediate or pending resignation and the launch, as of today, of a new “diamond” open access journal, Philosophical Logic."

Fifteen studies of thousands of people from four countries found that more politically conservative individuals rated slippery-slope arguments as being more logical than did politically liberal individuals.

I'm happy that my proposal for an introductory course on Homotopy Type Theory / Univalent Foundations at the European Summer School in Logic, Language and Information 2026 in Prague was accepted!

A great opportunity to make use of @egbertrijke's recently published book, @MartinEscardo's lecture notes (in Agda!) and @danielgratzer and @carloangiuli's book draft!

...we know that giving people various cues can make up for their poor understanding of the #logic of conditionals.

For instance, adding a scenario to a familiar conditional makes people far more likely to realize how others would test it...if it's a rule: dx.doi.org/10.3791/67794

"The main results have shown a significant main effect of the problem content (F(2, 147) = 16.60; p < 0.0001). Post hoc analyses revealed significant differences between neutral (M = 0.50) and permission content (M = 0.97), p < .0001. There was also a significant difference between permission and obligation rules (M = 0.28, p < .027). Overall, higher logical indices were obtained with permission content, and the lowest were registered with neutral rules. A significant main effect of scenario was also obtained (F(1,148) = 19.24; p < 0.0001). For all three types of content, the logical indices were higher in the condition where a Scenario was provided (M = 0.986), than in the No-Scenario condition (M = 0.464). Finally, a significant interaction between Scenario and Framing was registered: F(1,148) = 7.64; p < 0.006.""As shown in Figure 5, performance was considerably higher when the scenario was present rather than absent when [rule-like or] deontic framing was used, but there was little effect of the scenario with indicative framing."

In the 60s Wason showed people poorly understand the #logic of testing abstract conditionals (If..., then...).

In the 70s Johnson-Laird et al. found people DO know how others tend to test FAMILIAR conditionals (If someone drinks, then they must be 21).

After many more papers...

"The overall goal of the Wason selection task is to analyze how subjects formulate and test hypotheses from a conditional "If p then q" rule. This problem has been and continues to be one of the best experimental tools for studying the mechanisms underlying human reasoning. The original abstract version of the problem 1 is illustrated in Figure 1.""Thematic" versions of Wason's card selection task which involve familiar (rather than abstract) content.

The #logic behind Australia’s #SocialMedia ban for minors applies in spades for #AI.

Why in the hell aren’t we talking about that?
