Clearer Thinking by Spencer Greenberg as told to Sebastian Marshall
I’m a mathematician by background. I focus on the mathematics of machine learning, trying to get computers to learn from data to make accurate predictions. I founded a quantitative hedge fund that uses machine learning to invest in the stock market: it learns as it goes, and updates itself as it learns from the data.
I also founded the Clearer Thinking Project with the goal of getting people to challenge their own beliefs, improve their decision making, and avoid bias. The original inspiration for this work comes from cognitive science, where over the last few decades scientists have discovered numerous ways our brains mislead us when we’re making decisions.
