Hey everyone, I’m Erik Thor, an expert on using personality psychology for flow and personal development.

Erik Thor | Subtypes | 16 Personalities Subtypes

My name is Erik Thor and I’ve mapped out four healthy subtypes and natural variations within the 16 personalities and the four letter code. So what are the subtypes?

The Observers

ES, IS, IN and EN Subtypes

Observers are people that primarily focus on gaining information and experience about something. They primarily use the right prefrontal regions of the brain, focusing to keep brainstorming and keep processing a situation, until they have gained as much knowledge about it as possible. They can at times struggle to make decisions, and like to keep things open when possible.

The Reviewers

EF, ET, IT, and IF Subtypes

Reviewers are usually focused on how they feel about something, or on processing a situation logically. Their goal is to understand how things work or why things work the way that they do. They are good at scoring or rating life, 1-10, what did they like, and what did they dislike? How can things be improved or adjusted?

The Navigators

NJ, SJ, SP, and NP Subtypes

These subtypes are known to be explorers and discoverers, focused on getting from point A to point B. They tend to be project oriented types, that often focus on what’s next, what will happen, or preparing for what is to come. They’re usually on the go, walking in a fast pace, eager and enthusiastic, they are full of dopamine, but can at times be inconsistent.

The Deciders

FJ, TJ, TP, and FP Subtypes

Decision-making subtypes primarily focus on trying to reach or make a judgment about a situation, categorizing life into good or bad, right or wrong, yes or no. They focus on their judgment, and the left, prefrontal regions of the brain, focused on execution. They can sometimes struggle to listen or take in information if it doesn’t match their compass.

Mostly A’s: Observers
You have a natural curiosity and thrive on gathering information and insights. Your preference for understanding the world around you aligns you with the Observers, who are continually processing information to deepen their knowledge.

Mostly B’s: Reviewers
Your introspective nature and focus on evaluating emotions or logical aspects of situations suggest you resonate with the Reviewers. You excel at assessing and reflecting on various aspects of life.

Mostly C’s: Navigators
Your adventurous spirit and project-oriented approach place you among the Navigators. You’re always looking ahead, eager to explore and discover what life has to offer.

Mostly D’s: Deciders
With a decisive nature and a focus on making judgments, you align with the Deciders. Your ability to make quick decisions and set a clear direction is a hallmark of your personality type.

What are the 16 personalities subtypes?

What is a subtype?

Subtypes are variations within a personality type. They can be influenced by your unique development and your current mood and situation. This means that even if you have the same dominant personality traits as someone else, your subtypes could be very different.
