The Personal Coherence Index (PCI) is a behavioral assessment instrument designed to estimate the structural coherence of an individual's decision system. It measures the alignment between stated priorities, enacted habits, decision stability, and social reinforcement structures. The resulting score provides an orientation snapshot of how consistently an individual’s decisions support their intended direction.
The PCI produces a Normalized Coherence Score (NCS) ranging from 0 to 100. The score integrates responses from: • 18 behavioral items measured on a Likert scale • 3 situational indicators reflecting current environmental conditions Behavioral items contribute 65% of the score, while situational indicators contribute 35%. The model ensures that stable behavioral patterns form the primary signal while remaining sensitive to current environmental pressures.
Most participants complete the instrument in approximately five minutes. The assessment consists of 18 behavioral items and three situational indicators.
Assessment responses are processed locally within the browser session and are not stored on our servers. If a participant chooses to request the extended report, only the email address required for delivery is stored. Anonymous aggregated statistics may be used to calibrate the instrument and improve cohort comparison models.
Yes. Because the PCI measures current decisional alignment rather than fixed personality traits, repeating the instrument after meaningful changes or reflection periods can provide useful comparison points.
The Extended Analysis is a detailed interpretive report that expands the participant's coherence profile. It includes dimensional breakdowns across the four domains, structural conflict mapping, cohort percentile comparisons, and a structured six-week reorientation framework based on the participant's lowest-scoring dimension.
Project Coherence is an independent research initiative exploring narrative identity coherence as a measurable behavioral construct. The theoretical framework and scoring methodology are described in the Method document.
