Arrogance

Arrogance is commonly defined as : offensive display of superiority or self-importance; overbearing pride dictionary.com

I define it as: Believing one is correct without a thorough knowledge, or understanding.

In the Myers-Briggs system, an extrovert is someone who is externally focused while and introvert is someone who is internally focused. Both can be divided into two groups, Perceivers and Judgers. 

Perceivers focus on external information and internal decision making. This means that they will put off drawing a conclusion until they have enough information to be certain that conclusion is correct, and then they are only going to make the conclusion relate to themselves or to one thing because they would need to acquire more information before they could draw the same conclusion about someone  or something else.

Judgers are the opposite. They focus on internal information and external decision making. This means they will draw conclusions based off of information they already have and then later, if necessary, they will acquire more information.

How much perceivers put off conclusion, and how much judgers put off carefully acquiring information to make the right decision will depend on their level of arrogance.

If a perceiver is arrogant, they will believe they know what decision is the best for them to make at all times. This is why perceivers tend to be impulsive. If a perceiver is arrogant, they will believe they are aware of all the information that is presently available to them. Once a perceiver believes they have enough information, they will not hesitate to make decisions; thus, they impulsively act on the first thought that comes into their head.

If a judger is arrogant they will make decisions without considering new information. Judgers, can be known as people who are stubborn, inconsiderate, rash, and it all has to do with this. Quick judgements save time and energy, so it's very tempting to make them for judgers; however, one that is not arrogant will consider many different angles before reaching a single conclusion. The problem an arrogant judger will have, depends on their level of arrogance, : 1. Not considering new information at all when drawing conclusions, and 2. taking new information into consideration, but only acknowledging the information that reaffirms their judgements/conclusions.

A healthy, well rounded individual with avoid the pit-fall of arrogance. If you are a perceiver learn that even though the information may seem to clearly point to one course of action or conclusion, that you may be interpreting the information wrong. If you are a judger, learn that while the information you have seems to affirm your decision, you may be missing key bits of information that could alter your decision. All types are the risk of becoming arrogant, so all must be self aware and mindful.
