In this talk, I will address common misconceptions about the predictability of high dimensional complex systems, from weather to economic markets and social systems. Specific quantitative approaches that are able to predict human collective behaviors will be described. I will consider the possibility of developing early warning signs for crises in a wide range of natural and engineered systems. There are important implications for the future of science, and the responsibility of science for society. Questions and discussion about both practical (policy) and philosophical aspects of these issues (free will) are welcome.
