The KDI, answered straight
Everything people actually ask about the test: cost, privacy, accuracy, the axes, the 16 types, and where consent fits. If your question is missing, the contact page reaches a human.
What is the KDI?
The Kink Dynamics Indicator is a free, anonymous BDSM test for consensual power-exchange and S&M dynamics. It measures where you sit on four independent axes and maps you to one of 16 archetypes, each with a full written profile of how that dynamic tends to work.
Is the BDSM test really free?
Yes. The 48-question test, your complete type profile, sharing and partner comparison are all free. No account, no email address, no app to install.
How long does the test take?
About 7 minutes. There are 48 statements, all answered on the same five-point scale, plus two optional calibration questions at the end.
Is the test anonymous? Do you store my answers?
Anonymous by design. Your answers are scored inside your browser and never transmitted or stored by us. Your result lives in a permalink that only you hold; the only thing ever stored is a result you explicitly choose to donate to the open validation pool, and you get a deletion code for it.
What are the four axes?
Power (Dominant to submissive), Sensation (Sadistic to Masochistic), Channel (Psychological to Physical) and Structure (Ritualistic to Instinctive). Each axis is reported as an equal-share split between its two poles, never as a ranking or a score out of 100.
What do the four letters in my type code mean?
One letter per axis: your leaning pole on Power, Sensation, Channel and Structure, in that order. DSPR, for example, reads Dominant, Sadistic, Psychological, Ritualistic. The letters are shorthand for the permalink; the profile always spells out the full pole names.
What is a Switch, and how does the test handle it?
A Switch moves between poles depending on partner, mood or context. When an axis lands in the middle band, the KDI marks that axis as unresolved rather than forcing a side, and your profile explains what a mid-band reading tends to mean, including that it may sharpen on a retake.
How is this different from MBTI or 16personalities?
The four-axis, 16-type format is deliberately familiar, but the KDI measures something MBTI does not touch: consensual kink and power-exchange dynamics. It is built from its own item pool and scoring model, and it makes no claim to measure your general personality.
Is the KDI scientifically validated?
It is a self-report reflection tool, not a clinical instrument, and we are honest about that. Reliability statistics are computed live from the open validation pool of donated results and published once each statistic reaches its minimum sample size. Nothing is invented and no number appears before its floor is met.
What are the 16 types?
Every combination of the four axis poles yields one archetype, from the Architect to the Stormchaser. The Library page lists all 16 with their full profiles, and every profile is reachable without taking the test.
Which type is the rarest?
We only report distribution numbers computed from donated results, and only once the sample floors are met, so the honest answer is: check the open pool statistics rather than any invented rarity chart. Rarity also shifts as the pool grows.
Can my type change over time?
Yes, and that is expected. Context, partners and experience move people, and mid-band axes are especially likely to resolve differently between sittings. The retake flow preloads your previous result so you can compare sittings directly instead of guessing from memory.
What is the Intensity Dial?
A separate 1-to-5 self-calibration of how far you like to take things, from light and playful to edge-oriented. It is deliberately kept out of your type: two people with the same archetype can sit at very different intensities.
What is the Connection Frame?
An optional setting for which context you answered from: a single scene, an ongoing relationship, or a lifestyle dynamic. The same person can read differently across frames, which is exactly what the retake comparison is built to show.
Do I need BDSM experience to take the test?
No. The statements are written to work from instinct and imagination as much as from history. If you have never played, answer with what draws you; the result reads as a map of inclination, not a record of experience.
Is BDSM safe? Where does consent fit?
BDSM as practiced by the community is built on informed, enthusiastic and revocable consent, with explicit negotiation before anything happens. Frameworks like SSC (safe, sane, consensual) and RACK (risk-aware consensual kink) exist precisely because practitioners take risk seriously. A type is never a consent shortcut, and our Resources page lists real organizations for learning the craft properly.
Are D/s and S/M the same thing?
No, and conflating them is the most common mistake in casual kink talk. Dominance and submission is about authority and control; sadism and masochism is about sensation. The KDI scores them on separate axes because a person can run high on one and barely register on the other.
How does partner comparison work?
From your result you can send an invite link. Your partner takes the same test, and the pairing read computes chemistry axis by axis, a structural fit tier, and the specific conversations that pairing tends to need first. Both results stay in your links; we never see them.
Is there a paid version?
Everything currently on the site is free, including the full type profile. If a paid deep-dive report is ever offered, it will be a clearly labeled one-time purchase, never a subscription, and the free result will stay complete on its own.
Who is behind the KDI, and how do I reach you?
An independent small team; no institute, no invented credentials. Corrections, questions and findings are genuinely welcome via the Contact page.
