Start with the mental age test. Personality, memory, reaction, creativity, logic, and focus are here when you want a second angle.
The test the shelf is built around
The tests index opens on the mental age test because that is the center of Mindz. Thirty questions cover free days, changed plans, novelty, other people, and unfinished problems. Fixed weights turn the answers into trait bars and one estimated age, and the same answers always give the same age. Nothing is shuffled to freshen the card. The age is an entertainment metaphor you can share, not an IQ score and not a reading of brain health.
Personality, memory, reaction, creativity, logic, and focus sit beside it as second angles, not rivals. Personality sketches eight archetypes from how you decide, make, and stay with people. Creativity asks what you do when a brief is blank. Memory, reaction, and focus are short tasks with a clock. Logic is eight puzzles with a correct answer. Take mental age if you take only one, then use the others when a single number feels thin.
They are not the same instrument
A row of tests looks uniform until you ask what kind of answer each one accepts. Mental age, personality, and creativity are self-report: you pick the option closest to what you do, and weights add up. There is no correct box. Memory asks you to recognize words and rebuild a flashed grid. Reaction time is the gap between a panel change and a tap. Focus is a go or no-go round: tap the circle, leave the other shapes alone. Logic marks an option right or wrong.
Treating them as one score is how a website borrows the costume of a clinic. A slow tap is not a shy personality. A missed logic item is not a weak memory. A high creativity percentage is not a fast hand. Mindz keeps the pages separate so the result can say which instrument you used. Compare sittings of the same test. Reaction history is about taps on this device. Mental age history is about answers. Mixing the two charts invents a story the math never told.
What self-report can hold
Self-report is useful because you have watched yourself for years, and slippery because you also report the person you would prefer to be. The personality items are situations, not compliments: a messy problem, a sharp disagreement, a free afternoon. The archetype is the pattern among analysis, imagination, warmth, and steadiness, or a blend when two axes sit close. Creativity scores recombination, a playful constraint, or a step off the obvious path. A precise, careful style still gets a reading. It is a default, not a failure to be interesting.
Mood, language, and the week you are having will move those answers. That is not a defect. A second sitting can teach more than the first. Work and home can pull different archetypes without either being the true you. Treat the page as a hypothesis. If people do not rely on you as the name claims, the items caught a self-image. If they do, they caught a habit. The result is not a cage, a hiring screen, or a measure of kindness or intelligence.
Clocks, taps, and a short hold
The memory test shows a short word set, asks you to pick those words from a longer list, then flashes a grid to rebuild. The parts become one percentage. A high score means a small set survived long enough to recognize. It does not promise the same hold for names, study, or talk. A low score often means the grid overwrote the words. Interference is the point. Noise, a small screen, and an extra tab belong in the story before any claim about a permanent trait.
Reaction time is five waits. The delay changes so a rhythm will not help. Early taps are discarded, and an impossibly fast tap counts as a false start. You get an average of valid trials, in milliseconds. Phone, trackpad, and fatigue sit inside that number, so compare your own history on one device first. The focus test is a short go or no-go: for about forty seconds, tap only circles. Misses and false alarms both lower the score. A false alarm means the hand moved before the shape finished registering.
Right answers, and how to read a result
Logic is the odd page on a shelf of preferences. Eight items, one correct option each, scored as a percentage. You will meet a sequence, a syllogism, a conditional, the bat-and-ball trap, and a three-switch puzzle. Several are written to catch the obvious guess. Missing one or two traps is ordinary. A perfect score means you were careful with these eight sentences, not that every later argument will be sound. These are puzzles for practice. They are not an IQ battery and not a test of job performance.
Read the paragraph before you memorize the number, and name the instrument you used. Self-report wants a check you can run this week: do you delay reversible choices, or did you only say so? A timed task wants your last round, not a stranger on other hardware. A logic score wants another look at the item that felt easy. If the nickname feels decorative, the thinker quiz is a shorter sketch of an unclear problem. It will not replace the thirty questions.
Where a browser score stops
None of these pages diagnose a condition or rank you for school or work. They do not know your sleep or the week you walked in with. A surprising score is a reason to retake once in a quieter room and to read the notes on the page. It is not a reason to invent a clinical story from a percentage. When a task score rises, you mostly learned the task: a scanning route, a chunk, a slower tap. That is practice on the item, not a new identity.
A worried change in daily memory, attention, or mood belongs with a clinician, not with a browser. If ordinary life is getting harder and staying harder, talk to a qualified person. Mindz is for curiosity, a private half hour, and a score you may doubt. History stays on this device until you clear it. Share the label if you want. The answer sheet is not in the link, because it was never uploaded. The limit is part of the product, not a footnote you are meant to skip.
