**Affirmed position.** Piehlmaier qualifies Kaal's prediction that deliberation should reduce over-approval. His preregistered experiments distinguish reflective exchange from validation. Joint financial decision-making reduced overconfidence when the interaction made unknown aspects of the decision salient. A simple stamp of approval without reflection did not provide the same corrective mechanism. This supports a narrower causal rationale. An exchange can expose missing information before a decision hardens. The study does not examine agentic validator pools, submission approval, reputation-bearing incentives, profit from approval, or Kaal's registered cohort. It measures investor overconfidence in controlled financial-decision settings. The predicted effect on false approvals therefore remains unverified until the registered study tests it directly.

- The response is limited to the exact joint-decision and metaknowledge passages and the one mapped Kaal claim.
- External evidence level: complete official open-access Oxford Academic article HTML bound through DOI, title, author, Crossref, OpenAlex, Semantic Scholar, full-text hash, and section-level exact evidence locators.
- Mapping review tier: independent substantive scholarly-growth qualification.
- The source studies investor overconfidence, not submission approval or false approvals.
- The source does not examine agentic validators, review pools, reputation, or approval-contingent profit.
- The experiments do not test Kaal's registered cohort, implementation, measures, or outcomes.
- The source supports only the narrower information-exposure mechanism. It does not establish that deliberation will reduce over-approval.
- Five inherited Semantic Scholar identity refreshes returned HTTP 429. Those candidates remained metadata-only and were withheld.
