Welcome. My name is Eric Xu and I am enthusiast for turning data into meaningful insights. My research experiences have shown me that our brains are built for simplying decisions by creating heuristics (i.e. approximations of value). Specifically, I found that we generally over-value differences in quality and under-value differences in quantity. We are also innately bad at learning probability through experience and instead use salient events to heavily guide our choices. As decisions become more complex, the use of these heuristics increases due to our brain's limited memory and computational power. While these heuristics can be beneficial for fight or flight survival instincts, they can deviate far from optimality due to inherent biases in our perceptions. Data science, machine-learning, and statistics can be used to improve our ability to objectively assess value, improving decision-making. With proper A|B testing, the enhancements at the individual, corporate, and global level can be highly significant***.
