Peer-reviewed; ablation-study design isolates the marginal contribution of alt-data.\n\n**Caveats.** \"Significant\" is statistical-significance language, not magnitude — read the underlying paper for the specific lift before quoting a number. Multiple studies show direction; specific lift varies by dataset.\n\n**Implication / use.** Use to support the *direction* claim (\"alt-data improves default prediction\") without quoting a single number.
