The evidence-to-underwriting loop
The earlier briefing hypothesised that stronger evidence and controls could improve selection, losses, and underwriting economics. Treat that chain as a programme to validate, not an achieved Glacis result. GROUNDED · Glacis
Test each link
Section titled “Test each link”| Link | What would establish progress? |
|---|---|
| Declared control → execution | Reproducible evidence from the specified deployed path |
| Execution → observed effect | Downstream observation under normal and failure conditions |
| Evidence → useful review | Reviewers answer agreed questions with workable effort |
| Control → loss improvement | Suitable exposure/outcome data, causal alternatives and uncertainty |
| Loss experience → economics | Insurer-approved rating, terms, claims and capacity decisions |
Technical links can be evaluated in a bounded pilot. Loss-ratio improvement needs an experience base. A green test or receipt establishes neither a premium discount nor a safe harbour, profit share or capacity commitment. STABLE
Loss ratio, combined ratio, selection, rating, reinsurance and the underwriting cycle explain insurer decisions. The evidence supplier must understand those decisions without claiming to own them. STABLE
