The most popular couple pairing is "E+I" (e.g., ENFJ × INFP)—where the extrovert handles "social icebreaking" and the introvert takes care of "deep bonding." When two INTJs date, it's not uncommon to see them "spending an entire afternoon each glued to their computers, yet finding it utterly romantic."

According to statistics, INTP types spend over three hours daily on average contemplating abstract problems, often immersed in their own mental worlds. In contrast, ESTP types tend to explore the world through hands-on action, participating in outdoor activities three or more times per week on average.

Data from the American Marriage Research Institute shows that the divorce rate for ENFP and INTJ couples reaches 62%, as ENFPs seek novelty while INTJs are overly rational, resulting in significant personality differences. British police data indicates that INFJs, due to their excessive empathy and trust in others, are a "high-risk group" for telecom fraud.

The four dimensions of the MBTI (E/I, S/N, T/F, J/P) are actually extensions of Jung's theory of psychological types. The test was later developed by mother-daughter team Katharine Cook Briggs and Isabel Briggs Myers.

MBTI test results are not "set in stone"—long-term environmental changes (e.g., working in a social job for years) may cause your type preferences to undergo subtle adjustments, though core traits rarely change completely.

Among extroverts (E), ENFPs are known as "happy puppies," initiating social interactions more than three times daily on average. Meanwhile, over 60% of introverts (I) like INTPs report needing "an hour of alone time to recharge after talking to strangers."

ISFPs, known as "artists," have the highest proportion of people working in creative fields (painting, music, design) among all 16 types—accounting for nearly 35% of ISFPs surveyed.

Research indicates that the brains of INTJs exhibit heightened activity in the parietal cortex when processing abstract concepts, granting them an advantage in comprehending complex theories. Conversely, ESFJs show higher amygdala activity, making them more sensitive to emotional stimuli.
