You will know when an INTJ is angry because they will tell you.
My INTJ says they do not easily get angry because they are logical (it's possible a mature INTJ may never get angry). If you say something that is true about them, even if it's hard to hear, there is no reason for them to get angry at truth. Rather, they will take the true information and use it to better themselves. If you say something that is false, there is no reason to get angry because what has been said isn't true. Interacting with a lie is a waste of time and energy. Either way, you will find that INTJs are very neutral most of the time. And if for some reason they are not, they will tell you what and why.
