Curriculum vitae

Alessandro Santirocchi si è laureato con lode in Scienze e Tecniche Psicologiche presso l’Università LUMSA di Roma (2014) e in Neuroscienze Cognitive presso l’Università Sapienza di Roma (2016), dove ha poi conseguito il Dottorato di Ricerca in Neuroscienze del Comportamento (2022). È iscritto all’Albo degli Psicologi del Lazio dal 2021. Ha svolto attività di ricerca presso l’European Brain Research Institute (EBRI) tra il 2017 e il 2018 e, dal 2018, svolge attività di ricerca presso il Dipartimento di Psicologia della Sapienza. Attualmente è assegnista di ricerca presso il Dipartimento di Psicologia della Sapienza.

I suoi principali interessi di ricerca riguardano:

  • la modulazione della memoria in ambito forense

  • la suscettibilità psicologica alla disinformazione nei social media

  • le conseguenze neurocognitive delle concussioni negli sport da contatto 

Orari di ricevimento

Il ricevimento si svolge online su piattaforma meet, con orario e giorno concordato con il docente via email: a.santirocchi1@lumsa.it

The Simulation of Judgment in LLMs

Large Language Models (LLMs) are used in evaluative tasks across domains. Yet, what appears as alignment with human or expert judgments may conceal a deeper shift in how “judgment” itself is operationalized. Using news outlets as a controlled benchmark, we compare six LLMs to expert ratings and human evaluations under an identical, structured framework. While models often match expert outputs, our results suggest that they may rely on lexical associations and statistical priors rather than contextual reasoning or normative criteria. We term this divergence epistemia: the illusion of knowledge emerging when surface plausibility replaces verification. Our findings suggest not only performance asymmetries but also a shift in the heuristics underlying evaluative processes, raising fundamental questions about delegating judgment to LLMs.
