I am an independent research and programmer working at my own consultancy, Shapley Maximizers ÖU. I like to spend my time acquiring deeper models of the world, and generally becoming more formidable. I’m also a fairly good forecaster: I started out on predicting on Good Judgment Open and CSET-Foretell, but now do most of my forecasting through Samotsvety, of which Scott Alexander writes:

Enter Samotsvety Forecasts. This is a team of some of the best superforecasters in the world. They won the CSET-Foretell forecasting competition by an absolutely obscene margin, “around twice as good as the next-best team in terms of the relative Brier score”. If the point of forecasting tournaments is to figure out who you can trust, the science has spoken, and the answer is “these guys”.


I used to post prolifically on the EA Forum, but nowadays, I post my research and thoughts at nunosempere.com /​ nunosempere.com/​blog rather than on this forum, because:

But a good fraction of my past research is still available here on the EA Forum. I’m particularly fond of my series on Estimating Value.


I used to do research around longtermism, forecasting and quantification, as well as some programming, at the Quantified Uncertainty Research Institute (QURI). At QURI, I programmed Metaforecast.org, a search tool which aggregates predictions from many different platforms, which I still maintain. I spent some time in the Bahamas as part of the FTX EA Fellowship, and did a bunch of work for the FTX Foundation, which then went to waste when it evaporated.

Previously, I was a Future of Humanity Institute 2020 Summer Research Fellow, and then worked on a grant from the Long Term Future Fund to do “independent research on forecasting and optimal paths to improve the long-term.” I used to write a Forecasting Newsletter which gathered a few thousand subscribers, but I stopped as the value of my time rose. I also generally enjoy winning bets against people too confident in their beliefs.

Before that, I studied Maths and Philosophy, dropped out in exasperation at the inefficiency, picked up some development economics; helped implement the European Summer Program on Rationality during 2017, 2018 2019, 2020 and 2022; worked as a contractor for various forecasting and programming projects; volunteered for various Effective Altruism organizations, and carried out many independent research projects. In a past life, I also wrote a popular Spanish literature blog, and remain keenly interested in Spanish poetry.
