The question has been studied by people such as Carl Rogers, Carl Jung and Sigmund Freud. These men put together theoretical models that were intended to demonstrate how our personalities might develop within the often conflicting and always interacting elements of our internal and external structure. Among these models, though, Carl Jung developed a relatively uncomplicated approach on which many of the personality theories today have been based. Originally building his research off of the ideas of Sigmund Freud, who was his mentor for a while, Jung proposed that the personality was comprised of the interaction among four essential factors that related to the way in which a person gathers information and then how that person processes the information gathered. “Carl Jungs psychological theory fundamentally underpins most of the popular and highly regarded personality systems today” (Chapman, 2010), but it has not gone untouched. Following in his footsteps as well as they could, Katherine Briggs and Isabel Briggs Myers developed his ideas further to create a strong personality test that types people into one of 16 possible personalities (Carroll, 2009). The test found at 41 Questions did not provide the kind of four letter results I expected after doing research on personality theory and personality testing, but I was surprised at the accuracy of the results.

First, they have to take in information from around them through their five senses – hearing, sight, taste, touch and smell. Next, they have to make decisions about these things and what they mean. After he identified these functions, Jung then determined that there are two ways in which we might approach each of these functions. While taking in information, we rely to varying degrees on
