According to Tali Sharot we can make relatively accurate predictions when we look back in time and say, “Last month I was late for most meetings, enjoyed only half of the films I viewed, and received no gifts from my loving partner. Therefore, this month I am more likely not to be on time for the majority of my appointments, will probably only appreciate 50% of the movies that I watch and should not expect any gifts.”
