Losner Briones

¡Hola!

I am Losner Briones. This is my website. I am a predoctoral researcher in philosophy of social sciences at the Department of Logic, History and Philosophy of Science of UNED, in Madrid. Here, I pursue my PhD studies as an FPI [Formación de Personal Investigador] fellow at 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 project New Approaches to Evidence: Theoretical and Practical Developments (NATE), likewise funded by the Ministry. In addition, I am a member of METIS research group in analytical philosophy, based at UNED.

My primary research focuses on the predictive extrapolation of causal effects from experimental and quasi-experimental evaluations of policy interventions to real-world settings (effectiveness). More broadly, I address epistemological and methodological issues concerning evidence and causal extrapolation in the social sciences.

Currently, I am investigating how the evidence-based policy framework structurally excludes the investigation and evaluation of redistributive policies, including paradigmatic cases such as basic income. In parallel, I am exploring pluralistic alternatives to these limitations through mixed-methods research and the application of Evidential Pluralism to the social sciences. 

Here is my CV.
