Why surveys fail at the executive level
The L&D industry runs on Likert scales. Five points, smile a little, "I learned a lot today." For a 28-year-old high-potential who feels grateful for the development budget, that survey produces something close to a usable signal. For a 52-year-old executive who has been to twelve of these in the last decade, it produces noise. Demand characteristics dominate. Social desirability dominates. The signal-to-noise ratio collapses.
We needed an instrument that did not depend on the participant's willingness to disclose. That meant moving to the autonomic nervous system.
The three signals that make up the PTI
Heart Rate Variability (HRV) — the variability between successive heartbeats. Decades of psychophysiology research show HRV correlates with vagal tone, recovery capacity, and the body's response to social-evaluative stress. Higher resting HRV under simulated pressure means the nervous system is treating the scenario as a manageable challenge rather than a threat.
Galvanic Skin Response (GSR) — sympathetic activation measured at the palms. GSR spikes when the body decides something matters. We don't want GSR to drop to zero; we want it to spike on the right moments and recover quickly. The shape of the recovery curve is more diagnostic than the peak.
Behavioral telemetry — decision latency, gaze fixation, posture, verbal hedging, and a few proprietary scenario-specific markers. These come from inside the VR scenario itself. A leader who hesitates 1.4 seconds longer to push back on a board member is telling us something measurable about their identity signature.
How the three combine
The PTI is a weighted composite. Weights are not fixed — they shift across the protocol depending on which scenario family is being run. In an escalation scenario we weight GSR recovery and decision latency. In a board-confrontation scenario we weight HRV and verbal hedging. The composite is reported as a delta from baseline, not as an absolute score, because absolute scores between participants are meaningless without normalization we are not yet ready to publish.
What the PTI is not
It is not a personality inventory. It is not an IQ-style fixed measurement. It is not a leadership scorecard. It is a change instrument — designed to detect movement under controlled exposure, not to rank you against your peers.
If we ever get to a point where the PTI is used to rank, hire, or fire, we will have failed at the ethics layer. That is not the use case.
Where the science is open
The biggest open question: do PTI deltas measured in VR predict real-world performance shifts? We design every program with follow-up signal capture from line reports and stakeholders, but our N is still too small to publish. We will publish when it is big enough.
That is the deal we are offering — measurement instead of performance theater, with the honest caveats that come with measuring things this new.
