# Reading the Corpus Critically: Rhetoric vs. Evidence

These eight pieces are HBR *practitioner manifestos*, not empirical studies. Every source vault's enrichment overlay flags the same recurring gap between a defensible core and a rhetorical edge. A downstream agent should carry these calibrations.

**Rhetorical amplifications to soften:**
- "Consensus is *fatal*" ([[claim-consensus-fatal-post-ai]]) and "boards are *failing fiduciary duty*" ([[claim-boards-failing-governance]]) — directionally sound, normatively overstated.
- "Regulations add no value" ([[contrarian-regulations-lack-value]]) and "technical directors are a waste of time" ([[contrarian-recruiting-cyber-directors]]) — the balanced read is a hybrid.
- "Ad models *inevitably* corrupt agents" ([[claim-ad-model-misaligns-ai]]) — an inference, not a demonstration.
- "Near-universal consensus on nightmares" ([[claim-nightmares-create-alignment]]) — true for obvious disasters, false for contested, profitable ones ([[question-nightmare-disagreement]]).

**Numbers that are directional, not canonical:**
- SMB breach costs and budget figures ([[claim-smb-breach-cost]], [[claim-smb-budget-insufficiency]]) — order-of-magnitude, survey-specific.
- Failure rates ([[claim-failure-rate-bcg]], [[claim-failure-rate-reengineering]]) — proprietary or historical estimates with fuzzy definitions.
- "One year / five months," "6–10 weeks," "four decisions a year" ([[claim-standard-rai-too-slow]], [[contrarian-four-decisions-a-year]]) — consulting heuristics.

**And one outright fiction:** [[entity-anthropic-mythos-fable]] — "Mythos 5"/"Fable 5" never existed. The verifiable anchor by contrast: [[claim-cybercrime-losses-increasing]] (FBI IC3, $16.6B, +33%). Rule of thumb: represent the conviction, then attach the calibration.
