Measuring Logical-Rational Skills

Intelligence is a complex construct, and we recognize that it cannot be fully captured in a single measurement. However, this quiz offers a valuable opportunity to assess a specific aspect of human intellect, namely logical-rational abilities (IQ, or intelligence quotient). The value placed on this skill by society is considerable; therefore, it is advisable to take this into account and engage in its practice.

Questions of Varying Complexity

Our logical intelligence assessment consists of 35 questions, some of which may appear straightforward while others are more complex. The objective is to provide the most precise evaluation possible for the individual taking the test, while also taking into account individual predispositions. Be warned not to underestimate the apparently trivial questions. This challenge is appropriate even for younger individuals due to the diverse range of questions it delivers. Consequently, the interpretation of the final score is adjusted based on the user’s age; if you are under 18, please refer to this article: How to properly interpret the results.

No Time Limit

Originally, tests of this type have a time limit; however, we opted to utilize the time count solely for statistical purposes, thus allowing anyone to complete the quiz at their own pace. However, those who prefer a more conventional approach, should be aware that the recommended time limit for completing the test is 20 minutes.

TEST FEATURES

Measure your logical-mathematical skills.
The test consists of 35 questions, each with several answers and only one correct.
There is an invisible timer that counts the time but does not interrupt the trial.
This is a semi-professional test to be taken with full concentration.
At the end you will view the number of correct answers, the solution of each question and an estimate of you IQ.
Find out how test results are calculated and view an example result.
In addition, you will get a certificate of participation and an email detailing your result.

WHAT MAKES IT UNIQUE
Our IQ test differs from others found online for a couple of reasons. First, it contains as many as 35 questions, some of which are quite difficult while some are easier. We implemented this strategy to give everyone, very young people included, a way to find questions within their reach and not end up getting discouraged after a few minutes. In this regard, if you are under 18, you should know that IQ calculation varies according to your age. Learn more here: IQ score normalization.
The second special feature is that the timer does not intervene to interrupt the test when time runs out (20 minutes). So, if you want to take it easy and don’t care about getting an official result, you can take as long as you need.
It doesn’t end there. Upon completion of the challenge you will find a critical in-depth article on the subject of IQ tests.

🧠 Scientific Background: Psychology of Logical Intelligence

đŸ”Ŧ Overview

Logical intelligence represents the cognitive capacity to reason systematically, recognize patterns, solve mathematical problems, and think analytically. This fundamental aspect of human intellect underpins scientific thinking, mathematical reasoning, and systematic problem-solving across diverse domains of knowledge and professional practice.

đŸ›ī¸ Historical Foundation

Charles Spearman (1904): Introduced the concept of general intelligence (g-factor) and demonstrated that logical reasoning underlies performance across various cognitive tasks.

Louis Thurstone (1938): Identified logical reasoning as one of seven primary mental abilities, establishing its distinct role in human cognitive architecture.

đŸ”Ŧ Core Scientific Concepts

Deductive Reasoning

The ability to draw specific conclusions from general principles using logical rules and systematic inference processes.

Pattern Recognition

The cognitive capacity to identify regularities, sequences, and relationships within complex information structures.

🧩 Neurological Basis

Prefrontal Cortex Activation: Logical reasoning primarily engages the dorsolateral prefrontal cortex, responsible for working memory manipulation and abstract thinking processes.

Parietal Lobe Integration: Mathematical and spatial reasoning activate bilateral parietal regions, particularly the intraparietal sulcus, supporting numerical cognition and logical operations.

Neural Efficiency: Higher logical intelligence correlates with more efficient neural processing, characterized by reduced brain activation while maintaining superior performance.

🔍 Contemporary Research Findings

đŸŽ¯ Fluid vs. Crystallized Logic

Fluid Logical Reasoning: Novel problem-solving and pattern recognition that peaks in early adulthood and gradually declines with age.

Crystallized Logical Knowledge: Accumulated mathematical and logical knowledge that remains stable or improves throughout adulthood.

📊 Predictive Validity

  • Academic Achievement: Strong predictor of mathematical and scientific performance
  • Professional Success: Correlates with performance in STEM fields and analytical careers
  • Problem-Solving Transfer: Enhances ability to solve novel problems across domains
  • Decision Making: Supports systematic and rational decision-making processes
  • Learning Efficiency: Facilitates faster acquisition of complex conceptual knowledge

đŸ—‚ī¸ Theoretical Frameworks

Cattell-Horn-Carroll Model

Positions fluid reasoning (Gf) as a core cognitive ability that influences performance across multiple intellectual domains.

Dual-Process Theory

Distinguishes between automatic (System 1) and controlled (System 2) logical processing, with higher intelligence associated with better System 2 regulation.

Working Memory Theory

Emphasizes the central role of working memory capacity in logical reasoning and complex problem-solving abilities.

âš–ī¸ Assessment Methodology

Matrix Reasoning: Visual-spatial puzzles that assess pattern recognition and logical inference without relying heavily on verbal or mathematical knowledge.

Syllogistic Reasoning: Logical argument evaluation that measures deductive reasoning ability and resistance to cognitive biases.

Number Series: Mathematical sequence completion tasks that evaluate numerical pattern recognition and logical extrapolation skills.

đŸĨ Clinical and Educational Applications

Cognitive Assessment: Logical intelligence testing helps identify intellectual giftedness, learning disabilities, and cognitive decline in clinical populations.

Educational Placement: Informs decisions about academic acceleration, remediation, and specialized educational programming based on logical reasoning strengths.

Neuropsychological Evaluation: Assists in diagnosing executive function disorders and monitoring cognitive rehabilitation progress.

âš ī¸ Scientific Limitations

Cultural Specificity: Logical reasoning tests may reflect cultural values and educational experiences rather than pure cognitive ability.

Practice Effects: Repeated exposure to similar test formats can significantly improve scores, potentially inflating estimates of logical intelligence.

Motivational Factors: Test performance can be influenced by anxiety, motivation, and test-taking strategies rather than underlying logical ability alone.

Yury – Rating: IIIII
Lots of different types of questions and some trick ones. All in all, this is a well-made quiz with a style of its own. I recommend it.

Michael – Rating: IIIII
It is not the best IQ test I have taken but not among the worst either. Some questions are weird, I had never found them in other tests, I was sure I got them right but the quiz said I got them wrong.

Richard Mann – Rating: IIIII
I got 133/170 above average. I’m pleased with the result! Some puzzles were particularly twisted and I almost got fooled.

Vincent Viney – Rating: IIIII
Everyone tells me I’m very smart and I’m very good at school, so I think this exam is inaccurate and some questions dont make sense.
