You know your an INTJ if you study for 18 hours in a single day and then study a different subject to relax.
lmao
1. You know you're an INTJ when you go out of your way to go to the washroom on the upper floor of a library based on the calculation that the probability of getting a cleaner toilet is higher on the upper floor (where the more studious introverts are who are less likely to piss on the seats and so forth) compared to the lower floor. (Note: this is assuming that the washrooms are equal distances apart from where you are situated...obviously checking one bathroom if it's on the way to another would be even more efficient).
2. You know you're an INTJ when the word "footnote" gets used in about half your conversations.
3. You know you're an NT when you have a chessboard popping out of your gymbag.
4. You know you're an NT when you answer a question with a question (Note: other types do this occasionally but not to the degree NTs do on average).
5. You know you're an NT (or just a social dork) when you talk to a baby as if he or she is another adult.
6. You know you're an NT when the obsession of a simple idea can keep you up for nights on end. For example, in BGE Nietzsche poses the question "how could something originate in its antithesis?" I contemplated that on and off for months. More recently, I was inspired by a stock options trader who spoke about a project he did in a financial engineering course that tried to answer what would happen if an option price deviated from its theoretical value--say due to a large buy or sell order which was enough to offset the price from market equilibrium? I am neither trader nor commerce student...just an INTJ obsessed with mastering systems.
7. You know you're an NT when you categorize the utility of a person not according to a good-bad dichotomy, but according to probabilities and evaluations of the relative propensities for people to carry out actions and decisions which correspond and/or deviate from your personal belief system. Is that being judgmental? A question for an NT.
