Since the dawn of the Earth, organisms have been transforming, evolving and adapting into life as we know it today. Each animal has developed a brain that supports its needs.

The human brain is the most complex. It enables us to think, learn, and feel emotions. Why, if we have one of the most complex brains, do humans act in highly irrational ways? Why do they say or think one thing, and then do something that contradicts it? Why is it so difficult to do what we say we will do?

Blame Your Lizard Brain

The “lizard brain” is part of the human brain that dates back more than 285 million years. It is the part that is most similar across many different species; it is found in fish and the source of its nickname, lizards. It comprises the brain stem, cerebellum, and basal ganglia.

The lizard brain is the organ’s most dominant section. It controls primitive instincts such as reproduction, fear, and rage. It allows basic survival functions and therefore takes precedent in making major decisions. As such, it influences human behavior, sometimes ignoring what the other parts of the brain are saying. This portion of the brain offers strong resistance when we try to work against it. It is deeply rooted in our psyche and because it controls fear, a strong motivator, it makes us act irrationally.

Four steps to tame your lizard brain

Step 1: Name your lizard brain.

This exercise can help to define what is resisting rational behavior. Your lizard brain is the most active part and if you name it, draw a picture and visualize the thing that is causing the resistance you conquer it more easily. With a visible reminder of the “lizard” behind the irrational actions, you can become more conscious of it and find humor in the process.

Step 2: Develop self-awareness.

If you understand what drives your lizard brain you will become more aware what actions you’re taking because of it. The lizard brain is programmed to run on fear. If you are aware of your most vulnerable times and most limiting beliefs, you gain control. In those times, you can be on guard for the lizard brain to take over. Then you can consciously switch on the neocortex, which allows for rational thinking.

Step 3: Suspend judgment.

You will be more comfortable in relationships and social situations when you tame your lizard brain. Due to its innate fear response, your lizard brain may leap to judgement in these situations. The human being lifestyle is not as hazardous as it once was. Therefore, the lizard brain has adapted the “fight or flight” response to everyday social situations. It tends to make the snap judgments in every interaction and every minute. It remembers the time you were embarrassed, or places judgment on something due to the fear of failure. If you hold off on the quick judgments and take time to understand the situation, your will feel more comfortable. In turn, you will display positive body language and make others feel more comfortable. (Their lizard brains will be happy too!) These actions will facilitate productivity, build relationships in a work environment.

Step 4: Prepare to Be Uncomfortable.

Lastly, make strides to step outside of your comfort zone to tackle fear head-on. Our lizard brain acts from the desire to feel safe and comfortable. In order to fully tame our lizard brain, we have to become more comfortable with being uncomfortable. Interactions that cause discomfort and get us out of our normal interactions will allow us to change, adapt and grow.
