IQ tests are designed to measure a person’s reasoning ability and intellectual potential. They are not perfect indicators of intelligence but can reflect problem-solving speed, pattern recognition, and memory capacity.
In this free online test, you’ll answer 20 questions that evaluate logical thinking, spatial awareness, and number reasoning. The result gives you an estimated IQ score with explanation.
1. Please answer all questions honestly and independently. This is essential for obtaining valid results.
2. The personality analysis shows your personality tendencies, not your knowledge, skills, or experience.
3. The MBTI personality type descriptions are provided only for test takers to identify their personality type. There is no good or bad personality type, only differences. Each personality type has its own value and advantages, as well as disadvantages and areas that need attention. Understanding your personality's strengths and weaknesses clearly helps you better utilize your strengths while avoiding potential pitfalls in dealing with people and making important decisions.
4. There are 93 questions in total. There are no right or wrong answers. Please choose based on your actual situation.
Test results are for reference only.
The Myers–Briggs Type Indicator (MBTI) is a personality framework that groups people into 16 types based on four dichotomies: Extraversion (E) vs. Introversion (I), Sensing (S) vs. Intuition (N), Thinking (T) vs. Feeling (F), and Judging (J) vs. Perceiving (P). MBTI does not measure ability or mental health; it summarizes preferences in how you gain energy, process information, make decisions, and approach daily life.
Tip: answer based on long‑term, natural behavior rather than temporary roles at work or school.
An IQ test estimates problem‑solving performance (logical, spatial, numerical), while MBTI describes preference patterns. They answer different questions: IQ looks at speed/accuracy under puzzles; MBTI explains why certain environments feel energizing or draining. Many visitors use both: take the MBTI to understand collaboration style, and the IQ test to practice reasoning.
Identify environments that support your focus and motivation, then set habits that match your type.
Knowing teammates' preferences reduces conflict and speeds up decision making.
Type patterns can suggest tasks you may find energizing, but they should not be used as hiring criteria.
MBTI has mixed evidence in academic research. We present it as a reflection tool, not a diagnostic exam.
Preferences can look different across life stages. Results near the middle of a scale may shift with context.
