Losner Briones

¡Hola!

I am Losner Briones, a predoctoral researcher in the philosophy of the social sciences at the Department of Logic, History and Philosophy of Science at UNED, in Madrid. I am currently pursuing my PhD as an FPI [Formación de Personal Investigador] fellow within the research project Evidence and Mechanisms in the Social Sciences (EVISOC), funded by the Spanish Ministry of Science, Innovation and Universities. I am also involved in the projects New Approaches to Evidence: Theoretical and Practical Developments (NATE) and Data Modelling and the Problem of Ambiguity of Experimental Results, likewise funded by the Ministry. In addition, I am a member of the METIS research group in analytic philosophy, based at UNED.

My primary research focuses on issues of measurement, evidence, and validity as they bear on the inference and evaluation of causal effects in experimental and quasi-experimental studies of redistributive policy interventions. More broadly, I address epistemological and methodological questions concerning evidence-based approaches in the social and health-regulatory sciences.

At present, this research develops along two ongoing lines. One examines how the evidence-based policy framework systematically constrains the investigation and evaluation of the measurement of causal effects, with particular attention to paradigmatic cases such as basic income. In parallel, the other develops pluralistic methodological approaches, grounded in Evidential Pluralism, as alternatives to these limitations in the social sciences.

Here you can find my CV.
