You are one of the main characters in a detective novella. You are about to find yourself at the center of a mystery where your decisions could be the difference between life and death. A little more than a week after moving to Los Angeles, you twice narrowly escaped death from a sniper's bullet. Being new to the city, you can't imagine who could possibly have an axe to grind with you. So, you've come to me: Jack Wilshire, private detective. If we're going to solve this case and keep you alive, we need to follow the evidence and be as rational as we can. Our biggest enemy, outside of whoever is trying to kill you, is cognitive bias. By the end of the story, you will discover the most commonly identified cognitive biases and come to realize your own level of bias so that you can be better prepared how to be a more critical thinker.
