What is The Professor (Sergio Marquina)'s IQ?

Sergio Marquina plans the robbery of the Royal Mint of Spain over several years, trains the crew in a remote house and runs the operation from outside by phone. The show is built on the idea that he anticipates the police response. What it also shows is that he is outplayed more than once, usually when emotion enters the plan. A superb long-horizon planner who is human at the edges, which puts him in the low 140s.

Scene-by-scene evidence

  1. The Royal Mint plan

    Strong evidence

    First part of the series

    The Professor designs the robbery with detailed rules for the crew, an arrangement for hostages and a script for dealing with the police. Planning at this scale demands the ability to model many actors and their likely responses over weeks. It is the central evidence for strategy. It is also scripted by writers who know every step, so we give it strong weight for design and discount it for outcome.
  2. Preparing the team

    Moderate evidence

    Backstory in the first season

    He recruits specialists, builds a hideout and trains eight people to follow a protocol under stress. Directing others to behave predictably is a skill that scales with judgement of character. It shows insight into what motivates people, even if some of his picks cause trouble. We count it as moderate evidence for insight and organisation. The training is also where the plan first meets reality, since human beings do not behave like parts of a machine, and the show records both his success at organising them and the friction that follows.
  3. Contingency planning

    Moderate evidence

    Throughout the series

    The Professor has fallback plans for events that are likely to happen, and the show likes to reveal that an apparent setback was part of his design. Thinking in branches is the mark of a good strategist. Some of the reveals are cheats, because the audience was never shown the plan, so we credit the habit more than each individual trick.
  4. Facing Raquel Murillo

    Moderate evidence

    First part of the series

    Raquel is the inspector who gradually closes in on him, and the contest between them is the first real test of his plan. He manages her through conversation, but he also makes a personal error that exposes him. The duel is evidence that he can think against a skilled opponent, and also that he can be beaten by a mistake of his own.
  5. Improvising when the plan fails

    Minor evidence

    Later parts

    When the operation breaks down, he builds new plans in short order and uses the crew's skills in a different way. This proves a fast, flexible mind, although the improvised plans are less polished than the original. It is evidence that his ceiling is high but not absolute. The first plan is far better than the replacements, which suggests his real strength is preparation and that his speed under surprise is merely good. That distinction is why we keep him below the top tier of strategists.

What holds the number down

  1. Emotion undermines the plan

    First part onward

    His attachment to Raquel is the biggest crack in his planning. The show frames it as the human side of a calculating man, but a mind at 160 would have blocked that gap. It is why we treat him as brilliant but not at the top of the scale.
  2. Outplayed by determined opponents

    Later parts

    Alicia Sierra and others catch him in situations where his model of the police is wrong. Being surprised by an opponent is a legitimate mark against a character whose reputation rests on foresight. Each time, the show uses the surprise to raise the stakes, and the Professor responds with effort rather than a clean counter, which is the behaviour of a strong planner who can still be caught.
  3. The reveals are scripted

    Series-wide

    Many of his plan twists appear because the writers hide information from the audience. We cannot tell how much of his foresight is real and how much is editing, so we discount the neatest reveals and hold confidence at medium.

Why 142, and not higher or lower

Strategy and planning carry the estimate. Deduction and knowledge are good, and his ability to model how the police will react is the main evidence. Adaptability is the weak side: when Raquel Murillo, Alicia Sierra or events beyond his control break the plan, he improvises with real skill but loses ground. That mix is a strong strategic mind, not an unbeatable one.

The debate

The Professor invites comparison with Lelouch Vi Britannia and Light Yagami, two fictional planners who run a large operation from behind the scenes. Lelouch is more adaptive in real time, and Light is more ruthless in controlling information. The Professor's edge is patience and preparation, and his weakness is attachment. On pure planning ability he is close to them, but the repeated surprises keep him lower. He belongs in the same tier as Petyr Baelish.

The Professor (Sergio Marquina) IQ: frequently asked questions

Does Money Heist state the Professor's IQ?

No. The series presents him as a mastermind but never gives an IQ. Our estimate is about 142, range 132 to 152, based on his planning, the crew he trains and his mistakes.

Is the Professor smarter than Lelouch?

Lelouch is more adaptable in real time. The Professor is better at slow, preparation-driven plans. We put Lelouch slightly higher because he recovers from surprises more convincingly.

Who beat the Professor in Money Heist?

Several opponents get close, most notably Raquel Murillo and Alicia Sierra, and he is thrown by events he did not plan for. The details are spoilers, so we describe the pattern rather than the plot.
