Two tests, same data, opposite conclusions. Wei, Nathoo & Masson show how model misspecification makes Bayes factors contradict ANOVA in repeated-measures designs, and random-slope models resolve the paradox! 🔗https://www.sciencedirect.com/science/article/pii/S0022249626000039

If we only see the choices people make, can we mathematically deduce their hidden internal rankings? By applying Shannon’s Maximum Entropy principle, this paper derives an exact algebraic formula for hidden ranking probabilities in random utility models. www.sciencedirect.com/science/arti...

How does the brain tell correlation from causation across time? Niels Verosky shows one small tweak to a classic associative learning rule lets the same machinery behind temporal difference learning compute causal contingencies, not just co-occurrences.

The connectivity hypothesis, that stronger symptom interactions increase vulnerability to mental disorders, has been influential but never formally proven. Van der Mass & Waldop provide the first analytic derivation using mean-field Ising models of depression. www.sciencedirect.com/science/arti...
