INFJs and INFPs Under Stress

A way to identify each type is to understand how each type reacts under stress.
The INFJ a under stress will use their weak Extraverted Sensing function a bit more. The INFJ, typically a person with a lot of planning and foresight, will engage in a lot more impulsive behaviors. The INFJ may become stressed and can engage in risky activities like promiscuity, drugs and alcohol, or spending their money foolishly.
The INFP will use their weak Extraverted Thinking function more often under stress. This can cause the INFP to become uncharacteristically more abrasive and logical than normal. They may become more forceful and domineering, while streamrolling others feelings, something that they may regret later.
