Fan analysis by the LifeScore Editorial Team, reviewed September 2026. Contains mild spoilers. How we estimate
What is Kurisu Makise's IQ?
Kurisu has a stronger paper trail than almost any fictional prodigy: she is published in the journal Science while still a teenager, and she is the lab's theorist. She is the person who makes the time machine make sense. What limits her is range. We see her excel in one cluster of fields, and she is not shown inventing widely across domains or out-planning an opponent. That puts her in the exceptional band, not the extraordinary one.
Age-normed for an 18-year-old who skipped a grade.

Scene-by-scene evidence
A paper in Science as a teenager
Strong evidenceSteins;Gate, character background
Kurisu is introduced as an 18-year-old neuroscience researcher at an American university who skipped a grade and whose work has already appeared in the journal Science. It is an outside benchmark, not a boast from another character, and very few researchers of any age reach that stage. It is the anchor for her score, since it says the world inside the story treats her as a real scientist, not just as a clever student.Putting a theory under the microwave
Strong evidenceSteins;Gate, early and middle episodes
When the lab's modified microwave and phone begin to behave like a message system into the past, Kurisu is the member who treats it as a serious physics and information problem. She works out what the device would have to do to be reliable and what could break it. Turning a strange result into a structured investigation is what a strong researcher does, and it is why the lab's tinkering becomes a real project.Building the Time Leap Machine
Strong evidenceSteins;Gate, middle episodes
Kurisu creates a device that sends a person's memories back through the microwave, so that the person effectively leaps into the past. With Daru handling the hardware, she does the theory, and her neuroscience gives the leap a mechanism that fits her field. It is her clearest feat of invention, and it is the tool that lets Okabe try again and again to fix what has gone wrong. Without her theory the plot has no working machine.The last word on technical details
Moderate evidenceSteins;Gate, throughout
Kurisu regularly corrects Okabe and the others on technical points and does not accept vague claims. Within the show she is the one who ends technical arguments, and the story rarely proves her wrong. That consistency in a technical setting supports a low error rate in her own field, which is a large part of why she sits above the gifted band and not merely in it. Her authority is earned scene by scene.A theory worth stealing
Moderate evidenceSteins;Gate, later episodes
Her father, Dr. Nakabachi, is driven by a need to outshine her and takes her time travel theory to publish under his own name. The theft shows how valuable her idea is, and that it was hers to begin with. It is indirect evidence of originality, since someone who is expert in the field wants it badly enough to take it, and it is one of the reasons we score her invention high.
What holds the number down
Narrow evidence base
Steins;Gate, throughout
We see Kurisu working in a small set of fields: neuroscience, and the physics needed to make the time leap work. She is not shown designing across many domains. That keeps her estimate below a more general figure, even though what she does in her lane is excellent.Not a strategist
Steins;Gate, later episodes
Kurisu is not shown out-planning an adversary. In the key crises she relies on Okabe's persistence and the group's resources, and the plans that win are not hers. Her genius is scientific, not tactical, which limits how far the estimate can rise. Nothing in the story shows her closing that gap.Her idea is taken from her
Steins;Gate, final arc
Nakabachi steals her theory and the consequences run all the way to a world war. She could not stop him from taking her work, and she does not see him coming as an enemy in strategic terms. Being outmanoeuvred by an academic rival is a real, if modest, ding on her adaptability.
Why 155, and not higher or lower
Her credentials are external and checkable inside the story: a peer-reviewed paper, a research post at an American university and a skipped grade. Those weigh more than what other characters say about her. Her lab work is fast and, as far as we can see, correct. We hold her below 160 because she never outplays a serious adversary and because her read on people is uneven. 155 fits a genuine research prodigy.

Kurisu Makise's personality and MBTI type
Fans most often type Kurisu Makise as INTJ. Kurisu Makise is most often typed INTJ by fans: skeptical, independent and driven by ideas. INTP is the usual alternative.
- Openness
- Very high
- Conscientiousness
- High
- Extraversion
- Low
- Agreeableness
- Moderate
- Neuroticism
- Moderate
Kurisu is curious, disciplined and more introverted than she seems when arguing. She is kind underneath the sharp tongue, and her anxiety shows mostly around her father.
Personality typing is interpretive. It describes how Kurisu Makise behaves in the story and does not affect the IQ estimate.
The debate
The usual argument is Kurisu against Senku Ishigami, or against Okabe within her own show. Against Okabe there is no contest: she is the scientist. Against Senku she wins on theory and on a verified publication record, but loses on breadth and on the sheer volume of things built. We put her about ten points below Senku and comfortably above the rest of her cast. Against the wider genius cast she is a strong specialist, not a polymath.
For a real-world parallel, Einstein's relativity is the reason time travel is even discussed in physics. Kurisu's work picks up exactly where his ideas lead: what time is, and whether information can move through it. See Albert Einstein's IQ estimate.
