Professor Haynes gave an example of piolets CRM training: cockpit resource management. This training teaches new piolets how to communicate and teach them about perception. She explained that it takes demonstrations to convince people that we are flawed. We are very overconfident in our own cognition. We watched a video from theinvisiblegorilla.com of a man presenting an example of this. In this video he talked about the illusion of attention: that we think we arepaying a lot more attention to a lot more than we think. The illusion of memory if that our memories are much more perfect than we think they are. Failure source memory is when you remember something but you don’t remember its source of where you learned that information. Change blindness was an experiment done where a college student on campus asked a random stranger for directions to a building. In the middle of him giving directions, two men walk right between them carrying a table, at the same time the person who asked for directions was swapped out by someone else and most of the time the person giving the directions failed to notice. These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.The illusion of confidence is the confidence in our own abilities. Some examples given of this was someone tried to pay for his groceries with a million dollar bill, the clerk wouldn’t take it and he got really angry. He was overconfident in himself. An example given about this in class was someone was in a car accident and fractured their hand, one surgeon said they had to screws and rods in her hand and there was no other was of going about it. Three other doctors did not agree at all and said a cast would do the job. Another example is American Idol; thousands of people from every city think they have what it takes to win and be the #1, when the judges disagree and don’t send them through, they get angry and say, “I’m meant to do this, this is my dream, I’ll be back next year” when in allactuality they were horrible.Something else he talked about was receiving objective feedback on one’s own abilities. The experiment they ran on this was asking people at a competitive chess tournament to rate his abilities. They found that the players with the least amount of skills overrated themselves the most. The illusion of knowledge is when we think we understand somethingThe illusion of cause is our ability to figure out the cause & effect. Our minds are built to draw out sequence of events or make decisions. An example of this is when a medical doctor is able to give you a diagnosis based on certain symptoms.Our illusions keep us from seeing or navigating
