Why the name System1?
Our inspiration comes from groundbreaking prospect theory research by Nobel laureate Daniel Kahneman and his partner Amos Tversky. Their findings distinguish between two modes of thought: System 1, which is fast, automatic and frequent – similar to how users engage online – vs. System 2, which is slower, more effortful and infrequent.
