The science behind Sensotype
Plain English. No apologies. No medical claims.
What Sensotype IS:a sensory-wiring framework that maps how each person’s nervous system takes in the world differently — and what that means for connection. Twelve archetypes. The adaptive engine usually narrows you to one in about thirty questions, and stops the moment it’s confident.
What Sensotype is NOT: not a personality test. Not Myers-Briggs (different theory, different goal, different methodology — see the FAQ). Not a clinical instrument. Not a diagnosis. Not a horoscope. Not a sealed verdict on who you are.
A personality test asks who you ARE — your traits, your preferences, your cognitive style. Sensotype asks how your nervous system TAKES IN the world: what it notices, what it misses, what’s loud for you and what’s quiet. Different question, different layer. Two people can score nearly identical on a personality test and still drive each other quietly nuts at every dinner — because they’re not noticing the same room. Sensory wiring sits underneath personality. A lot of what looks like a personality mismatch turns out to be a sensory mismatch Sensotype just couldn’t see.
How it could be wrong:if 1-year test-retest archetype stability falls below 65% across a representative sample, we will publish that and reconsider the framework. We’re committing to that bar in advance, because the difference between a working model and a vibe is whether anyone is willing to be wrong about it in print.
Who built it:Dr. Michael Neal — optometrist by training, 25 years of practice in northeast Pennsylvania — and the Sensotype team. Influences: sensory neuroscience, interpersonal-difference research, and the lived experience of two and a half decades watching how differently people’s nervous systems sort the same room.
What we’ll publish: annual reliability data, archetype-distribution data, and group-comparison data. First publication scheduled for 12 months post-launch, on the same anniversary cadence as the Sense Check.
The skeptic FAQ
The answers below are the ones we’d give a thoughtful friend who’s been burned by a personality test before. None of them say “trust us.”
Is this scientifically validated?
Not yet. Sensotype is a working framework, not a peer-reviewed instrument. The 13-factor model is drawn from sensory neuroscience and interpersonal-difference research, but the test-retest data, the cross-cultural validation, the formal psychometrics — that work is in front of us, not behind us. We will publish reliability data annually. The first publication is scheduled for 12 months after public launch.
Why should I trust this over MBTI?
Different theory, different goal. MBTI sorts people into types based on Jungian preferences and is mostly used in HR contexts. Sensotype is a sensory-wiring framework — it asks how your nervous system takes in the world, not what your cognitive preferences are — and it exists to make connection easier, not to assign you to a quadrant for a corporate offsite. Both can be useful. They aren't trying to do the same thing.
What if I score differently next time?
Two reasons that might happen. One: Sensotype isn't perfect (it's a v1; expect drift). Two: mood, sleep, recent life events all color how you answer. We treat the secondary archetype as real signal. If your top two flip and the third is far behind, you're probably one of the two and the difference is which one is louder this month. If the entire top three reshuffles, that's a measurement issue and we want to know about it.
Can my archetype change?
Some traits are stable — sensitivity, anchoring — and don't really shift across a lifetime. Others — sociality, pace, seeking — do shift, especially across major life transitions. Your archetype is a label that summarizes both. So: probably not in 18 months, possibly across a decade. The Sense Check is the annual recalibration that tracks this without making it weird.
Who profits from this?
Dr. Michael Neal, the founder, and the Sensotype team. The free Sensotype, the result page, the share assets, the explore page, the SenseMap, and the basic pair dynamics will stay free. Premium tier (Argument Translator, full pair playbooks, Pairing Drips, group reports) is paid. Honest answer: this is a business, and we'd rather tell you that than dress it up as a passion project.
Is this a cult?
Said playfully, answered honestly: no. There is no in-group/out-group, no escalation funnel, no charismatic guru, and no event you have to attend. We'd be a bad cult — we tell you the framework's limitations on the second screen.
What if my friend's result doesn't fit them?
Two possibilities. Either Sensotype got it wrong (it does, sometimes — flag the thumbs-down on the result page and we'll see the data), or your read of them is the part that's off (also common; Sensotype is partly designed to surface that). Either way, the conversation is the point. The label is a starting hook, not a sealed verdict.
What would convince you Sensotype is wrong?
If 1-year test-retest archetype-stability falls below 65% across a representative sample, we'll publish that and reconsider the framework. If the connection-type predictions don't track relationship outcomes any better than chance in a controlled comparison, we'll publish that. We're committing in advance because that's the difference between a working model and a vibe.
Why 12 archetypes — not 4 or 9 or 16?
Twelve is what fell out of clustering the 13-factor model for distinctness AND memorability. Four is too few — the differences between Quiet Reader and Loud Reader collapse into one bucket, and the framework loses descriptive power. Sixteen is too many for everyday recall — most users can't name them all without reference. Twelve gives you enough resolution to feel seen and few enough labels that you can hold them in your head.
Why these 13 factors?
They were chosen for two things: independence (each factor explains variance the others don't), and behavioral consequence (each factor predicts something you can actually see in someone's life — not just self-report). They draw from sensory neuroscience (sensitivity, seeking, processing speed), interpersonal-difference research (sociality, anchoring, pace), and the lived experience of clinical practice in optometry, where Mike spent 25 years watching how people's nervous systems sort the world differently before he had a framework for it.
Who built this?
Dr. Michael Neal — optometrist by training, 25 years of practice in northeast Pennsylvania, Sensotype's founder, working with a team across research, engineering, and product. Influences: research traditions in sensory processing, interpersonal differences, and connection psychology. The honest framing: this is a working model built by a curious practitioner with a team around him, not a credentialed psychometrician's career-capstone instrument. That's the bet — that the practitioner's lens will see something the credentialed-only lens misses.
What will you publish?
Annual: archetype-stability data (test-retest at 12 months), archetype distribution data (population frequencies), group-comparison data (do same-archetype pairs report different relationship outcomes than mixed pairs?). All public. All on the same anniversary cadence as the Sense Check.
The white paper
Long-form (~3,000 words) for the skeptic who keeps clicking. Covers the 13-factor model, clustering decisions, planned validation work, and the falsifiability commitment in detail. Coming with the public launch.
