Molodinow’s message is that while sloppy thinking and our biology may drive us to think in illogical ways about randomness, we can use the science of probability to interpret more accurately what we observe in the world around us. Garnash stalked past, stopped, and backed up to snarl wordlessly at him. In addition he shows that often the true probability of an event is not intuitive, yet we think they are and mistakenly base serious life decisions on them. Evolutionary biology and faulty intuition lead us to make mistakes that can radically distort our perception of reality. We incorrectly attribute causes to random events, make flawed decisions in the face of uncertainty and consistently underestimate the role of luck. For instance, if you flip two coins, there are not three, but four potential outcomes: (heads, heads), (heads, tails), (tails, heads), and (tails, tails).
