Rich Bello explains cognitive bias as a deviation from rational thinking that causes decision errors, especially under time pressure. Our brains evolved to make fast, life-saving choices like fleeing predators, but those same shortcuts misfire in modern situations. A timed math test shows how speed forces heuristic-driven mistakes.

So the definition of a cognitive bias is a deviation from our rational and objective thinking process. They may lead to errors in our decision making. Is this some type of cruel hoax by the great architect of our minds? Right? No. This is created to be able to enable us to make fast decisions in times of danger. Like when a saber toothed tiger is chasing us. Our brains gather all the information really quickly. And then based on our past experience, in order to make the fastest decision, we have to act quickly. So what happens though, when you make decisions fast? We can make errors. I'm sure you guys remember your 8th grade math class where the teacher would say, show the work. When you're doing a math problem, like, show the work. Test time, right? Teacher's like, all right, 30 more seconds. There's no time to show the work. You just do the best you can. So that's what these cognitive biases are. If you're just doing the best you can quickly. They were meant for olden times when we had in an environment where tigers were chasing us, literally. They're not so much meant for these days where we're not having these emergency type situations.
