In this episode I talked with Dr. Quinn Cummings (@resus_bae) about the topic of cognitive bias and some ways we can reduce the influence of biases in our practice. Quinn is an emergency physician with a special interest in this topic.

During an average shift an emergency medical provider makes hundreds to thousands of decisions. To make these decisions, our brains use a combination of conscious and subconscious information. We tend to think that all our decisions are made objectively but, in fact, much of our decision making comes from knowledge or ideas that we are not even aware of. This is the concept of cognitive bias. A cognitive bias is a systematic error in thinking which can skew our ability to process information properly and accurately. This can lead to an improper diagnosis or treatment path for our patient. There are numerous examples of specific biases such as anchoring bias, confirmation bias, premature closure, etc. We discuss a few examples in the podcast but we encourage you to research more to see which ones you may be more susceptible to (see resources below).
