7:00 What Is Confirmation Bias?
- Let’s start by saying for whatever reason this is It seems to be an intricate part of our human psychology.
- Human beings form an opinion or a view. Once this view is formed we tend to want to be correct about this view. Therefore we turn around and embrace only information that confirms to what our point of view is. And not only do we embrace information that confirms our point of view but we also outright will reject information that doesn’t, or come up with reasons and excuses as to why this piece of the puzzle doesn’t fit in with the rest.
8:00 How Does This Apply To Hazmat?
- We often talked about Hazmat as being a jigsaw puzzle. Every bit of information that we receive whether it’s from SDS sheets, meters, interviews, patient assessment, our own observations, are all parts of a jigsaw puzzle. if we were doing a jigsaw puzzle and we took a puzzle piece that clearly wasn’t connecting with the next puzzle piece we would naturally put it off to the side and realize that that puzzle piece didn’t fit into that puzzle. With confirmation bias, we attempt to jam the puzzle piece into a place where it doesn’t fit.
- This leads us to literally become prisoners of our own assumptions which is really difficult in Hazmat because so often we’re constantly making assumptions and putting pieces of the puzzle together as information is coming in. We generally start to formulate a view or an opinion as human beings right off the bat. and there’s a certain challenge in the Hazmat Community to being able to figure it out. and it actually makes us feel good when we come across information that validates what it is that we believe.

12:00 How Can We Avoid It?
- There are a couple of different ways to go about fighting confirmation bias. One of the techniques is to use something called a ladder of inference. The ladder of inference is a thinking process that we go through anytime we make a decision. and one of the things confirmation bias does is it tends to let our minds jump these various steps or rungs on a ladder. By holding true to each step we can start to reduce The natural effect of wanting to believe things that support our point of view.

27:00 Gambler’s Fallacy
- With the gambler’s fallacy, you expect past events to influence the future. A classic example is a coin toss. If you toss a coin and get heads seven times consecutively, you might assume that there’s a higher chance that you’ll toss tails the eighth time
- This becomes dangerous when these assumptions are put into other information to form a logical outcome. Your input is flawed your output is bound to be flawed.
