By "invent" I presume inventio which is to say "finding or discovering of something"[0]. The concept of risk is virtual in the comprehension of all human beings and it takes abstraction[1] and analysis to extricate the concept from the understanding. In which case, you should absolutely expect many people to discover the concept independently, as it were. (See logos or logos spermatikos.)
