Damn I thought you were extroverted based on some of your posts lol

Im probably a Type A Introvert

“Type A Introverts These people are sometimes the life of the party and are often mistaken for classic extroverts, but this is a practiced skill. Being social is work for these people, and can only be practiced when the tank is full. Key here is to not engage socially when the tank is low.”

Most people think I’m like 70% Extroverted or something, but what it comes down to is where you derive energy. It’s pretty draining for me to be around others all day long, whereas an extroverted person may feel energized by all the people and talk.

I am captivated by the moment, no doubt - but it’s draining for me over long periods of time.

Agree with this. Professor Jordan Peterson (love him or hate him for cultural commentary, he is a highly acclaimed clinical psychologist) runs understandmyself.com which hosts a 10 minute, big 5 based personality test. From memory the test cost $10 (and you can only take it once) but the end product with validated descriptions in-line with your percentiles was nothing short of eerily accurate.

 
The Invisible Hand:
MBTI has no scientific validity.

Scientific validity? Not sure what that means.

But, it has proven to be an effective management tool for businesses that choose to use it.

It’s all over Pub Med. Its not like there is a lack of research on it. What do you mean?

https://www.ncbi.nlm.nih.gov/m/pubmed/3193230/?i=2&from=/8265080/related

‘Decision-making styles: managerial application of the MBTI and type theory.’

“The MBTI is useful not only in identifying individual preferences, but also in developing effective managerial and working terms. Knowledge of one's own type and the type of others can help managers motivate others, maximize human resources, persuade others, and gain cooperation”

It may prove an effective management tool, but I imagine that is because of the power of suggestion. MBTI flatters people by describing all of the possible types in positive terms, and this may make people feel encouraged, empowered, etc.

It has been shown to be unreliable, meaning that there is little consistency in the same individual's results over time or using different versions of the test.

It has been shown to lack validity meaning there is no evidence that understanding a person's type allows one to predict behavior or occupational effectiveness.

It also happens that the binaries are not actually mutually exclusive. I.e., portraying certain traits (excluding perhaps Introverted / Extroverted, which also appears on the Big Five) as opposites is unwarranted.

The Big Five was created by factor analysis. They looked at personality survey results and figured out which responses correlated to one another and found five distinct clusters and some subclusters for each. Rather than arbitrarily ginning up some random distinctions, researchers performed empirical work to find the traits that are non-overlapping, predictive, and reasonably consistent over time. One nursing school study from 1988 does not a consensus make.

Your viewpoint and response is much better than I expected. I can see your points.

There is a lot of research and data on MBTI ~ 250+ studies on PubMed.

I am quite biased to MBTI as I have been to a few conferences on it through my old company and have met an author on the topic who has explained some of the key aspects to me.

It is imprecise at times and yes the same person can arrive at different classifications throughout their life, but I feel knowledge of it can help the person - as well as providing a form for proper organizational behavior in companies.

I once interviewed a guy who defined his entire existence around that categorization. He gave me 3-4 answers about his personality based on that and got mad when I pointed out there might be something more nuanced in his personality rather than 4 capital letters and the discourse behind it.

Never discuss with idiots, first they drag you at their level, then they beat you with experience.
 

The actual Myers-Brigg site charges 50 bucks for the assessment, but they'll provide you with additional items and tools on top of providing you your results.

There are several sites that provide a free version of the 16-type assessment:

http://www.humanmetrics.com/cgi-win/jtypes2.asp - I can't seem to find the site I used a few years back, that one had a questionnaire of close to 100 statements... but I did this one this week, it's got less than 65 statements and I came up INFJ again.

https://www.16personalities.com/free-personality-test

 

All my personality tests have come back negative.

Jokes aside, I'm an INTJ based on tests and the descriptions I've read of them. I have my outgoing moments, but being around groups of people drains my energy.
