Beginners Guide to Understanding the Cognitive Functions

The Myers and Briggs personality system is more complex than it appears at first glance. Beyond the basic four-letter structure, the overall framework of the MBTI® assessment includes eight cognitive functions, which reveal how your mind works and how you relate to the world at large. They guide your interactions with others and your environment. They also explain how your belief systems emerge and how they influence your thinking and behavior.

Do you ever meet someone and feel like you already know them? While there are 16 possible personality types in the Myers and Briggs system, some are more common than others. 

The most common personality types appear time and again in the general population, so you can start to notice similarities between the way people think, socialize and structure their lives.

Here’s everything you need to know about the most common personality types and their shared traits.

What is Introverted Intuition?

It doesn’t matter if you’ve just taken the TypeFinder Personality Test or you’ve known about the 16-type system for some time—there’s always something new to learn. One of the least understood details of the 16-type system is type dynamics. Each personality type is made up of four type dynamics, and one of these is the primary cognitive function that determines how you view the world and interact with it. For example, for INFJs and INTJs, their primary function is something called Introverted Intuition. 

What is a Social Introvert—and Could You Be One?

Under the right circumstances, an Introvert can enjoy socializing just as much as an Extravert. An Introvert who enjoys it immensely can be classified as a social Introvert, in recognition of their need for regular and stimulating interactions with other people.

The social Introvert is still not an Extravert. But their need for social contact is undeniable, and that motivates many of their actions.

What is Type A Personality? 7 Signs that you May Be One

Odds are you’ve heard someone mention they’re a Type A personality before. Maybe you’ve even labeled yourself as Type A without understanding its whole meaning. The Type A and Type B personality theory is nothing new. The theory, first developed by cardiologists Meyer Friedman and Ray H. Rosenman, has been around since the 1970s. These doctors based the Type A and B Personality Theory upon the idea that people can be categorized into two groups based on their behavioral responses to stress. The theory also includes two other Types, which are less publicized, Type C and D.  

What Is an Introvert? 7 Traits All Introverts Have, Even If They Don’t Know It

Although you’ve probably heard the terms “Introvert” and “Extravert” thrown around in conversation, you might not know exactly what these traits mean and how they differ. It’s easy to say Introverts like to stay in while Extraverts like to go out, but few people know why. Because  generic statements are so prevalent, people often find these personality terms confusing and unknowingly perpetuate falsehoods about them. So what is an Introvert, exactly?
