Or is it simply a case of seeing patterns in randomness? Genius scholars and Nobel Prize winners have dedicated years to answering this question. A substantial number of the decisions we make each day are rooted in two opposing beliefs: that if something happened before, it will happen again – or if it happened before, it probably won’t happen again.
