My Dual Personality

Recently, Douyin keeps recommending INFJ personality videos to me.

My earlier test results and algorithmic recommendations had always been INFP.

From high school through university, I took the sixteen-type MBTI test four or five times. The result barely changed: INFP. Eventually I assumed I was a typical idealist prone to wandering thoughts.

Recently, however, INFJ videos filled my screen, describing it as a one-in-a-hundred personality, about 1% of the population. Personality tests had become popular again, and I had not taken one for a long time.

I thought: this is the AI age; why not let AI analyze me directly?

I gave several different large models my recent writing and reflections, asking them to combine those with memories of our earlier conversations and assess my personality.

Interesting.

Their answers were remarkably consistent: INFJ.

Claude said:

INFJ is driven by meaning and emotional attachment. It uses analysis to understand its inner life, rather than control the world.

Impressively, Claude concluded that I seemed more like a combination of INFJ and INFP.

—Below is Gemini’s answer—

Apparently Douyin’s algorithm knows something.

It recommended INFP for years, then suddenly switched to INFJ. It seems to have noticed something before I did.

Thinking about it, that is rather nice.

Does this mean I have collected INFP’s lively romanticism and INFJ’s deep insight?

Accidentally, I have become a master of “dual personality.” Ha! All the advantages of two personalities for free.

Later I thought seriously about it. Changing personality is quite normal.

MBTI’s sixteen-type classification has a rigorous psychological model behind it and can serve as a tool for self-narration. It helps many people first understand themselves and differences between people.

Like a mirror, it helps us understand our emotions, behavioral patterns, and why we once felt so lonely or sensitive.

But a mirror remains a mirror.

It can reflect you, but cannot define you.

Humanity’s millions of different souls cannot fit easily inside sixteen little boxes.

A childhood INFP result does not mean I must remain there forever. A few letters cannot write someone’s destiny in advance.

People are fluid.

Experience reshapes us, pain refines us, love nourishes us, and time quietly changes everything.

This recalls a point in a video when the eminent psychologist Philip Zimbardo joined Bilibili: personality tests such as MBTI help us understand our present and past selves, but should not box in our future selves.

A beautiful comment beneath it remains with me:

“Personality is not a fixed specimen, but a flowing poem.”

After the personality test, I decided to tease AI a little.

I asked:

“Based on all the above, seriously analyze which zodiac sign I am.”

The models’ responses were interesting this time.

Claude was very “honest,” saying directly:

Astrology has no scientific basis. An attempted analysis would probably just flatter my descriptions, so it refused to guess.

Gemini was different.

It gave a long, serious analysis of my expression, emotional tendencies, and thinking habits, then solemnly answered:

Capricorn.

Something felt wrong.

Why was it so certain? It had not sounded so firm when analyzing personality.

No.

It probably already knew my birthday.

Well then: working backward from the result to a supposed cause.

I asked further, and that was exactly what happened.

It had not “calculated” my sign; it had inferred backward from existing information.

We often imagine AI as overly mysterious, as though it can see through someone’s soul.

It reasons, empathizes, and offers emotional support.

But this “understanding” does not necessarily equal genuine insight.

So keeping a little skepticism matters when talking with AI.

Still, even knowing personality tests are not absolute truth and astrology may be unreliable, humans keep pursuing the eternal question:

“Who am I, really?”

Because people naturally long to be understood.

Everything flows; nothing stays. Time strips away shifting appearances. The indelible underlying color beneath the ashes is the real you and me.
