Individual skill

converging-evidence-design

Use when the user is designing a survey and using single items per construct, OR when the user has survey results that they suspect are unreliable but can't pinpoint why. Triggers: "I'm using one item to measure X — is that enough?" / "should I have multiple items per construct?" / "I want a robustness check for my survey" / "my survey result looks fragile" / "I want to validate this finding with another question". Default: For every survey hypothesis, design at least 2 items using *different elicitation methods* (state vs. choose, recall vs. infer, abstract vs. concrete, or different framings of the same construct). Not for: experimental-design robustness (treatment vs. control arms); survey-mechanics fixes (use pilot-protocol).
