A team of researchers has found a way to solve a long-standing puzzle in philosophy, known as Goodman's New Riddle of induction. The riddle asks how we can be certain that our scientific theories are correct, given the complexity of the assumptions and data we use to test them. The researchers argue that the key to solving this puzzle lies in recognizing that philosophy of science is a science itself, with its own strengths and limitations. They also suggest that the concepts of complexity and direct measurement should be understood together, rather than separately. This approach is a fresh take on the problem, and challenges the common assumption that the riddle cannot be solved.
