Meaning:

The Myers-Briggs Type Indicator (MBTI) personality test classifies individuals into two main types: the “I person” representing introverted personalities and the “E person” representing extroverted personalities. The primary distinction between these types lies in their preferences. The “I person” seeks solace in solitude while the “E person” gains energy from social interactions. These terms can be likened to popular concepts like “social phobia” and “social butterflies.” However, it is important to note that the results of the MBTI test are not definitive, as personal attributes can change over time, and individuals can differ even within the same personality category.

Example:

A: 你觉得自己是I人还是E人？

Nǐ juédé zìjǐ shì I rén háishì E rén？

Do you identify more as an “I person” or an “E person?”

B: 总体而言我不喜欢社交，可以算是I人。

Zǒngtǐ éryán wǒ bù xǐhuan shèjiāo，kěyǐ suàn shì I rén。

I personally lean towards the “I person” as I generally dislike socializing.
