Cognitive Reflection Test – 7 Reasoning Practice Questions

What Is the Cognitive Reflection Test?

The Cognitive Reflection Test (CRT) is a type of reasoning exercise built around questions that seem easier than they are. A familiar-looking number or a quick mental shortcut may suggest an answer immediately, but checking the wording can lead you somewhere else. The interesting part is not simply whether you can do arithmetic. It is whether you notice when your first answer deserves a second look.

This ReflexBenchmark page is a seven-question cognitive reflection practice quiz. It combines three well-known reflection problems with four additional everyday reasoning questions. You type a whole-number answer, or choose to skip, and receive your score and explanations only after completing all seven. The question order changes between attempts, but the question set does not.

It is suitable for trying out short logic problems and noticing your own answering habits. It is not a standardized CRT administration, clinical assessment, intelligence test or dependable measure of how you make decisions in daily life.

How to Take the Seven-Question Quiz

1. Read the whole problem. The exact wording matters; small phrases such as “all but” or “overtake” can change the question.
2. Enter an answer from 0 to 999. The game accepts whole numbers rather than sentences or multiple-choice selections. Follow the unit shown beneath the question, such as cents, minutes or a position number.
3. Submit, or skip if unsure. The “I don't know — skip” control records an unanswered question and advances the quiz. You cannot revisit a previous item during the same attempt.
4. Finish all seven. There is no visible countdown timer, but the page measures how long you spend on each question.
5. Read the result review. After the last answer, the page shows the total correct, rounded accuracy, median answer time, number skipped and an explanation for every question.

The quiz intentionally withholds correctness feedback until the end. This keeps later answers from being influenced by seeing explanations halfway through the attempt. If you switch away from the browser tab during a running quiz, the current attempt is interrupted and no score from that attempt is submitted; restart to try again.

How the Cognitive Reflection Score Is Calculated

The main score is straightforward: one point for each correct response, from 0 to 7. An incorrect number earns zero points. A skipped question also earns zero points. There is no partial credit, speed bonus or automatic penalty for taking longer to think. All seven problems contribute equally to the total.

The accuracy percentage on the result screen is calculated as (correct answers ÷ 7) × 100, rounded to a whole percentage. Because the quiz always evaluates seven items, answering five correctly means your result is 5/7; skipped questions still count as part of the seven-question denominator.

The server checks the submitted answer records against the fixed quiz answers before accepting the result. That helps reject inconsistent uploads. It does not independently prove that every browser response was unaided, or that a response time is a laboratory-grade cognitive measurement.

Understanding the Result Chart and Answer Times

The seven-bar result chart reflects what you actually submitted in that attempt. Green identifies a correct answer, and orange identifies an incorrect or skipped response. Each bar represents one question in the order it appeared for you. The chart is a picture of your own seven decisions, not a graph of other players or a made-up performance curve.

The page also reports your median answer time. It records an elapsed time for each question using the browser clock, including time spent reading, reasoning and entering your answer. Those seven values are sorted; the fourth value is the median. For instance, if the sorted times were 3, 4, 5, 7, 9, 12 and 18 seconds, the median would be 7 seconds. Skipped items still have recorded elapsed time.

Median time is descriptive, not a second score. A thoughtful answer that takes longer still earns its point. A fast answer that is wrong still earns zero. It is also important not to compare browser times with clinical norms: device responsiveness, interruptions, familiarity and question-reading speed all affect them.

Open “Show all 7 answers and explanations” to see the original wording, your submitted number (or “Skipped”), the correct number and a brief explanation for each item. Reviewing why an intuition failed is often more useful than focusing only on the total score.

Why These Reasoning Questions Can Be Misleading

Some problems encourage a quick pattern match: an answer comes to mind because the question sounds similar to one you have solved before. Others depend on a small logical distinction that is easy to overlook on the first reading. The useful habit is to turn the sentence into a simple statement you can verify rather than trusting how familiar the answer feels.

Fast intuition and deliberate checking

Popular explanations of cognitive reflection sometimes contrast intuitive “System 1” thinking with more deliberate “System 2” thinking. That vocabulary can be a useful way to discuss why a tempting answer arises. Still, a seven-question browser score does not isolate two mental systems, measure their activity, or label someone as an inherently “intuitive” or “analytical” thinker.

A practice example without spoiling the quiz

Suppose two objects cost $14 together and one costs $6 more than the other. Guessing that the cheaper object costs $6 would make the other $12, giving $18 in total. A more reliable method is to let the cheaper object cost x, then solve x + (x + 6) = 14. That gives x = 4 and the more expensive object costs $10. The lesson is to check the relationship and the total, not simply choose the first plausible number.

Similar verification habits help with quantities, order, elapsed time and wording puzzles. You do not need advanced mathematics for these seven questions. You do need to distinguish what the question actually states from what you expected it to say.

Practical Ways to Approach Each Problem

• Restate the task. Before entering a number, identify exactly what the question asks you to count or calculate.
• Test the obvious answer. If a number appears immediately, substitute it into the original sentence and check whether all conditions hold.
• Use a tiny equation or timeline. Relationships between costs, production rates or intervals are often easier to inspect when written out.
• Separate certainty from familiarity. A question you remember from a previous attempt is different from one you solved independently today.
• Skip rather than guess blindly. Skipping is available if you cannot find a defensible answer. Review the explanation later.
• Avoid speed as the only goal. The primary score rewards correct answers, not how quickly they were entered.

If you want to compare attempts, note which questions were already familiar and whether you changed your approach. A higher result after reading the explanations may reflect memory of those fixed answers. That is normal for practice, but it limits the value of treating repeat scores as fresh measurements.

What Your Score Can and Cannot Tell You

A result of 3/7, 5/7 or 7/7 tells you exactly how many answers matched this page's fixed answer key. It does not translate into an IQ score, a percentile among people your age, a diagnosis or a prediction about your finances, risk-taking or everyday judgment. Even when a rank appears, it compares eligible recorded attempts on this website under comparable settings—not a representative population sample.

The original three-item Cognitive Reflection Test was introduced by Shane Frederick in 2005. Research studies can use particular questions, sampling methods and administration conditions to investigate relationships between reflection and other behaviors. This page adds four practice problems and is not the original three-item instrument. Its raw results should therefore not be compared directly with published research averages.

Other limits matter as well: the questions are reused on every attempt, some are widely known, browser-based times vary, and the quiz does not control for outside assistance. Use the result as feedback on a short set of reasoning exercises, not as a fixed verdict on your ability or personality.
