| When measures share a common method (such as self-report), correlations among them are inflated by the shared method rather than reflecting only the construct being measured; agreement among same-method instruments is not independent confirmation. | Podsakoff, MacKenzie, Lee & Podsakoff, "Common Method Biases in Behavioral Research," Journal of Applied Psychology 88(5), 2003, 879-903 | https://experts.arizona.edu/en/publications/common-method-biases-in-behavioral-research-a-critical-review-of-/ | verified |
| Organizational diagnostics (health index, culture survey, engagement study, maturity assessment) read collective perception, the observable midstream; the generative cause is the organization's capacity, which sits upstream and which perception instruments cannot reach. Neurometric is the organizational diagnostic that reads the capacity layer. | Vanaya NeuroTech, Module 01, Neurometric Essentials v1.0, sections 1.2, 2.1-2.2, 3.1 | Internal document | internal |
Re-angle note (Lyra revision)
Week 4 was re-angled from "the assessment stack that agreed and was still wrong" (a hiring / individual-assessment frame, judged wrong altitude for a CEO audience) to the recurring organizational diagnostic that reports the what and never the why. The intellectual DNA is preserved (agreement among instruments reading the same layer is not triangulation of the cause), lifted from HR hiring instruments to board-level organizational diagnostics. Consequences for sourcing:
- Sackett, Zedeck & Fogli (typical vs maximum performance) dropped. It anchored the individual-hiring version and does not fit the org-diagnostic frame. Still available for any future individual-performance piece.
- Podsakoff added. Common-method variance is the clean, top-journal anchor for the shared-method point: several perception-based surveys agreeing is method-bound agreement about the perceived state, not independent evidence of a cause. This was held in reserve from the original week-4 sources; now used.
- Positioning: the close frames Neurometric as the deeper organizational diagnostic, per the guardrail's Positioning section.
Handling notes
- No named instruments or firms. Diagnostic types are rendered as generic categories (organizational health index, culture survey, engagement study, maturity assessment). The module's internal comparator tables were not reproduced.
- Villain control. The instruments are treated as valid and precise about what they measure (perceived state); the gap is located as a structural boundary of the perception layer, not a defect. No positioning against any provider.
Blade discipline
Week 3 owns "why change reverts under load" (Dias-Ferreira, Walsh & Ungson). Week 4 owns "why your diagnostics report the symptom and not the cause" (Podsakoff). Neither reuses the other's citation, and week 4 no longer overlaps week 1's or week 2's individual-level material.
