Mission, Vision, and Commitments
It is our mission to provide the most accurate online intelligence test in the world.
Our vision is to provide a fair, transparent, and accurate method for individuals worldwide to assess their intelligence in a standardized manner.
Commitment to Fairness
We strive to create a level playing field for everyone by:
- Developing a culturally fair test: Our test comprises questions that utilize straightforward language and minimal academic knowledge to minimize cultural bias. While we recognize that creating a completely unbiased test is impossible, we are committed to making it as equitable as possible.
- Offering unlimited test attempts: We understand that factors such as performance anxiety, sleep deprivation, or needing more practice can impact test results. By allowing individuals to take the test as often as they wish, we aim to provide everyone the opportunity to achieve their true intelligence score potential.
- Providing open access to a vast array of questions: Our extensive question bank spans numerous categories, ensuring that no one could feasibly memorize all questions. This approach guarantees equal access to the test questions for everyone, regardless of their location.
Commitment to Transparency
We recognize that personal intelligence is a sensitive subject, and as such, we strive to be transparent about the choices we make in assessing intelligence. Our commitment to transparency includes:
- Providing open access to all test questions: After every test, we share the metadata from the questions answered by the candidate, including the average IQ of the users who answered the question, the average ratio correct per IQ range and the median time taken to answer the question.
- Being open about our scoring method: We aim to make our scoring method as straightforward as reasonably possible, ensuring that everyone understands how to achieve their best results.
Commitment to Accuracy
Our mission is to provide the most accurate online intelligence test in the world by:
- Continuously calculating the predictive value of each question for every user, allowing us to estimate a user's intelligence as accurately and efficiently as possible.
- Conducting large-scale testing: Our test has been taken by over 2 million users worldwide, resulting in a highly accurate data compilation of individual questions and test results used to determine intelligence scores.
- Regularly updating our content: We constantly add new questions and categories while removing questions with lower predictive value, ensuring that our test remains up-to-date and accurate.
Our scoring method is designed to provide a fair and accurate assessment of each user's intelligence. The process consists of several key elements.
Time Limit and Question Structure
Users are given 20 minutes to answer as many of the 30 questions as possible. The questions are divided into 20 difficulty levels, based on a Rasch and a 2PL item response theory model derived from the results of over 500,000 individual test-takers who completed the test.
Adaptive Question Level Adjustment
All users begin the test with a level 1 question. For each correct answer, the difficulty level increases by 1, and for each incorrect answer, the level decreases by 1. Points earned for a correct answer correspond to the difficulty level of the question (e.g., a correct answer for a level 12 question earns 12 points). Incorrect answers do not result in any points being earned.
Raw Score and IQ score Calculation
The points earned from correctly answering questions are summed to create the user's raw score. This raw score is then compared to the entire population of test-takers to calculate the user's IQ score, with a median of 100 and a standard deviation of 15.
