Thanks for coming to my site! I’m Spencer, a mathematician and entrepreneur. This is where I record my thoughts about decision making, rationality, education, philosophy, science, and other subjects that I enjoy thinking about. I especially love exploring topics like “How can we modify our expectations to be happier?”, “Why do smart, knowledgable people disagree so often?”, and “How can we become more rational decision makers?” This site now has 50 of my essays. I hope you enjoy them!
