In this paper we review some recent results about the efficiency of random strategies for complex systems. Inspired by physical systems, we discuss several successful examples of the beneficial role of randomness in the realm of socio-economic systems.

We dedicate this paper to Alfredo Ferro to celebrate his distinguished career.
