I have an interest in cognitive personality type or the MBTI. As a study of the types, here are my personal notes and observations about each of the types that I have encountered.
| ESTJ | ESTP | ISTJ | ISTP |
| ESFJ | ESFP | ISFJ | ISFP |
| ENTJ | ENTP | INTJ | INTP |
| ENFJ | ENFP | INFJ | INFP |
Empathic as hell, very observant of social dynamics and unsaid things; sees right through people to their true motivations. Deeply cares about the inclusion of everyone. Furious at injustice and mistreatment. Rarely puts themself in a leadership role, but is skilled at managing group dynamics in a harmonious manner. íAlso unproportionally insecure about themself and their judgements; an "ungrounded" kind of person who is open to being anything, somehow. Kind of so insanely open that they lack discernment, to a degree. Doesn't know their own boundaries that well, it's like the concept of boundaries is somewhat of an abstraction. Strange fascination with the dark and destructive aspects of humanity. Smart as hell. Tend to go overboard with drinking, etc.
Creatures of HABIT! They want things done the way they have always done it. Skeptical and critical of new ideas. ISTJ's are the ones to say things like "I've never been there before", "we didn't do it like that in my childhood".
Like to do whatever feels best for them in the moment. Impatient and incapable with things that seem boring or pointless. Does not like to think deeply about meaning or implications. Very concerned with physical appearance and their physical surroundings; fitness and health freaks; can be obsessive about order and cleanliness. Sensitive to things they find disgusting or overstimulating environments. Low social inhibitions or shyness, unafraid of putting themselves out there. Friendly and energetic disposition. Find great enjoyment and humor in stirring the pot, provoking and being inappropriate.
Workaholic busybodies, want to be involved in everything. Prioritize being dutiful and responsible for the causes and projects they are involved with; enjoy being of help and useful to others – a number one supporter. Intelligent, logical and fact-oriented. Have nerdy interests; enjoy theoretical learning with concrete practical applications. Very sociable peoples-people, can talk about almost anything freely and openly, conversations focused on current events, people and previous experiences "what happened and how did I feel about it"; little interest in considering underlying meaning, implications or abstract possibilities. Very attached to and romantic about their past experiences, can explain the physical details of their memories vividly, as if replaying a film scene. Very focused on physical details. Have a deep internal value system, moral and concerned with doing what's right according to their standards. They feel things deeply and intensely on some level, but it's rarely expressed save for when they are under too much stress to handle or their emotions have festered inside for a long time. There is a very soft heart with deep and strong emotions at the core, and they have sensitive and romantic souls, but it's an aspect of themselves which is usually ignored or hidden. Great at interpersonal problem solving and conflict resolution when prompted, find pragmatic solutions, but might have difficulty with understanding and honoring others' emotions, focusing instead on what's right and what makes sense. Have difficulty understanding and expressing their own emotional motivations. Concerned with doing the right thing and being a good person in their relationships, struggle with guilt when this conflicts with their busy lifestyle and career/personal ambitions. Extremely sensitive to expressions of anger, emotional outburst, passive aggressiveness, sarcasm from others.
Other things: Will lie if it seems like the most effective thing or in order to "save face" and upkeep status. Pretend to be "too tough", but secretly very concerned with how others view them. Seem to have a deep seated fear that they are a "bad person", and when they have hurt someone or made interpersonal mistakes, struggle intensely with guilt in a black-and-white manner and are unable to forgive themselves. Try to supress, deny, avoid or run away from mistakes or difficult emotions instead of properly repairing (to a greater extent than others). After expressing true emotions or vulnerabity, they will later redact the truth by rationalizing it away and saying they meant something else.
"I will get what I want when I want it" type A kind of people, want to get things done in the most efficient way in the quickest manner with the least hassle. Hard workers, fast paced, high energy. Unapologetically ambitious and confident, but have a tendency to have unrealistic expectations. Very impatient and get frustrated at obstacles, whether that be systems, rules or people. Quite often angry, aggressive or irrtable. Get frustrated at things like "talking about it" or "thinking things through" or "considering options" because they are quick problem solvers and often have the best solution already. Inconsiderate of others and their feelings at times; does whatever is best for them without considering the effects on others. Not above arguing with, yelling at or subjugating others if it is "necessary" or effective. Can be socially smooth, manipulative and exploitative in order to get what they want. Smart, mentally quick and agile, pick up on things (which interest them) quickly. Socially quick witted, clever and hilarious company; manouver social scenes with great ability and confidence; great socialites. However, despite being incredibly sharp, insightful and socially skilled, they have moments where they seem completely oblivious to pretty basic things in regards to others. Can be arrogant and seemingly completely oblivious to their own flaws and shortcomings; pride coupled with low self-insight impedes them from adjusting course when necessary. Tendency to blame others or systems which get in their way instead of looking inwards and correcting their own behavior. Can be hypocritical and blame others harshly for things they are worse at themselves. Seemingly oblivious to their own feelings, will deflect and deny till the bitter end. Deny frustration and anger despite obvious aggression (because to them the external problem is the focus; their aggression is not a part of it). Tendency to walk around with a lot of stress; do not pick up on bodily signals of stress and exhaustion until they manifest in other physical symptoms (because they prioritize effectiveness and efficiency over things like physical needs). Respond to being hurt (i.e. in a relationship) with pretending theyr're above it and do not care (because being hurt is a weakness). Have difficulty considering others' perspectives or even apologizing when they have caused harm or hurt; seem to take it as a personal attack and focus on being right (because they know they are ultimately right). They do feel guilt, hurt, sadness, insecurity and regret like everyone else – they are not inhuman! But they would rather not dwell on it and be weak, and their pride seems to get in the way of processing a lot of things. Tendency to withdraw, loom and feel lost and "out of sorts" when long term plans stall or expectations and dreams are dashed and they are not making progress towards their own goals, but seem unable to admit or consider their own actions or strategy contributed to it, or to adjust their expectations (which seems like it would feel like failure or loss).
