Five reasoning questions

Three pattern puzzles and two word-and-number questions, from easy to harder. There is no time limit here. Pick an answer to see whether you are right and to read how the rule works.

Pattern questions

  1. Question 1

    Easy

    Which option completes the grid?

    Worked solution

    Two rules run at once. Down the columns the shape stays the same (hexagon, triangle, circle). Down the rows the size increases: small, then medium, then large. The missing cell is in the third column (circle) and the third row (large), so it is a large blue circle. Every shape is blue, so colour carries no information.

  2. Question 2

    Medium

    Which option completes the grid?

    Worked solution

    Three attributes change independently. Fill follows the row: solid, outlined, solid. Colour follows the column: red, blue, yellow. The number of triangles forms a Latin square, so each row and column contains one, two and three triangles once. The bottom row already has three and one, so the missing count is two. The last column is yellow and the last row is solid: two solid yellow triangles.

  3. Question 3

    Hard

    Which option completes the grid?

    Worked solution

    In every row the third cell has as many shapes as the first two cells combined: 1 + 1 = 2, 1 + 2 = 3, and 2 + 2 = 4. Shape and colour stay fixed within the row. The bottom row is yellow diamonds, so the answer is four yellow diamonds.

Words, numbers and logic

  1. Question 1

    Number series

    2, 3, 5, 8, 12, 17, ?

    Worked solution

    Look at the gaps between numbers: +1, +2, +3, +4, +5. The gap grows by one each step, so the next gap is +6 and 17 + 6 = 23.

  2. Question 2

    Logic

    Ana is taller than Ben. Ben is taller than Cy. Dev is shorter than Cy. Who is second tallest?

    Worked solution

    Put the facts in one line from tallest to shortest: Ana, Ben, Cy, Dev. Ben is second.

The short answer

Psychologists define intelligence as a general mental capability: reasoning, planning, solving problems, thinking abstractly, understanding complex ideas and learning quickly from experience. Being smart is not the same as knowing a lot, being educated or being quick in conversation.

The five questions below sample that capability in a few minutes. They cannot tell you how smart you are, but they can show how you cope with rules you have not seen before. Studies find our own guesses about our intelligence correlate only about .30 with measured results, so a test tells you more than a hunch.

What psychologists mean by smart

A widely cited 1997 statement by 52 researchers, written by Linda Gottfredson, described intelligence as a very general mental capability. It includes the ability to reason, plan, solve problems, think abstractly, comprehend complex ideas, learn quickly and learn from experience. It is not book learning, a narrow academic skill or test-taking smarts.

That definition is why matrix puzzles and number series are common in IQ tests: they need no specialist knowledge, so they show how well you handle something new. It is also why being knowledgeable, well-read or good at trivia is a different thing. Those are learned, and they reflect how much time you have had and what you cared about.

Signs that hold up, and ones that do not

Popular signs of intelligence and what the research supports
SignWhat the research says
Learning new things quicklyPart of the standard definition of intelligence. Speed of learning from experience is central.
Strong reasoning with unfamiliar problemsThe core of most IQ tests. Working memory and reasoning are strongly related.
A rich vocabularyVocabulary reflects accumulated knowledge and correlates strongly with IQ, but also with reading habits and education.
Curiosity and openness to new ideasA modest, consistent positive link. Openness is the personality trait most tied to intelligence.
Faster processing on simple tasksA modest relationship. People with higher IQ tend to respond a little faster on simple decision tasks.
A messy desk, poor handwriting or staying up latePopular claims with little or no solid support.
Being socially awkward or bored at schoolCommon stereotypes. There is no good evidence they signal high intelligence.

Why guessing your own intelligence is hard

People are only moderately accurate at judging their own intelligence. Freund and Kasten pooled 41 studies and found self-estimates correlate about .33 with measured scores. Patzl and colleagues pooled 115 samples covering more than 36,000 people and found .30, and .25 in general-population samples. Self-estimates were most accurate for numerical ability, at about .43.

A correlation of .30 leaves most of the difference between people unexplained. It means your own sense of how smart you are is a starting point at best. It also means a friend calling you smart, a good school record or a high vocabulary are weaker evidence than they feel like.

Ways to find out properly

  • A supervised test. A psychologist-administered test such as the WAIS is the accurate route, and it costs money.
  • A score you already have. If you sat the SAT, ACT, GRE or similar, the score converters give an estimated IQ with a range.
  • A longer online test. A 25-question reasoning test gives you more than five questions can. Treat the result as an estimate.
  • Practice with question types. The IQ test questions and answers page has twelve worked examples.

Am I smart? Common questions

How smart am I?+

Only a standardised, supervised test can measure it. A quick reasoning quiz gives you a first impression of how you handle new problems, and self-assessment alone is a weak guide, correlating only about .30 with measured intelligence.

What makes someone smart?+

Psychologists point to general mental capability: reasoning, planning, problem solving, abstract thinking, understanding complex ideas and learning quickly from experience. Knowledge and education add to that, but are not the same thing.

Am I smart if I do well at school?+

Good grades correlate with intelligence but also depend on effort, teaching, health and motivation. Plenty of high-ability people do badly at school, and plenty of hard workers do well with average ability.

Is getting all five right a sign of genius?+

No. Five untimed puzzles are a taste of the format, not a measure. A high score means these rules are easy for you, and a lower score means little, especially the first time you meet this kind of puzzle.

What IQ is considered smart?+

The average is 100. Scores of 110 to 120 are above average, 120 to 130 are high, and 130 and above is about the top 2%. Those labels are conventions, and every person is more than a number.

Why are we bad at judging our own intelligence?+

We compare ourselves with the people around us, we remember successes better than failures, and we rarely get to do the same task as everyone else under the same conditions. Even across dozens of studies, self-estimates correlate only about .30 with measured scores.
