Turning personality information into better decisions

This is Part 10 of our series on Personality Neuroscience. Click here to read from the beginning.

Now that you understand some of the underlying causes of Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism, you're probably wondering... now what?

This knowledge about personality and the brain is interesting, but it's only valuable if you translate it into real-world action.

With scientific personality models like the Big Five and DISC, you can learn more about yourself and better understand your own behavior.

I think about these different levels of personality like a car...


DISC tells you how to drive the car.


The Big Five tells you about the parts of the car.


Personality neuroscience tells you how the engine works.

You can use personality tools to understand the people closest to you and improve your relationships.


Crystal (the producer of this blog) is a personality platform that provides assessments, predictions, and coaching tools for your friends & coworkers.

You can be more successful in your career by adapting to other people’s unique personalities, communicating more effectively, and learning what truly drives them.


For example, when working with a person that has a high level of Neuroticism, ambiguous feedback may produce a more negative response than negative feedback.


When you’re working with a team of people with high Extraversion and Openness, understand that details may fall through the cracks if left to their own devices.

Most importantly, you can take better care of your brain.


There is substantial evidence that you can increase your serotonin levels with exercise, diet, meditation, and exposure to natural light.
