    Transcript
    Now, let’s take a look at these heuristics in action a little bit more and we’re goingto look at the impact that it can have. So in terms of logic and our decision-making. So humans are not always logical. We do things, and you’ve done it, I’ve done it. You know people around you have done it, and you’re saying, well, that kind of doesn’t make sense. How did you come to that point? Well, heuristics are the shortcuts that we mentioned and these actually increase the efficiency in decision-making but can lead to errors in judgment. Because you’re following that shortcut and the shortcut is just that, you’re skipping steps, you’re introducing error. And it also, if you’re following a heuristical approach, you are following these shortcuts, you can actually make some mistakes in terms of choosing the inappropriate heuristic, and so we call that an error in judgment. So representativeness heuristic is a tendency to judge the likelihood of an event occurring based on our typical mental representation of those events. So, again, if you already know the outcome or you think you know the outcome and you have a representation of that outcome, of that shortcut, then that’s going to determine sort of what you believe and what you think. So let’s go through an example so this makes a little more sense. I’m going to present these three things here. So, what is more likely to happen to you? Right now, I’m asking you, getting crushed by a vending machine, getting killed by a shark, or getting killed by a tornado? So, is it A, is it B, is it C? Is it the Coke machine, is it Jaws, or is it a twister? Now, your inkling might be, say, well, yeah, shark attack because sharks...
