Most are genuine namesakes of PEPs, such as an ordinary David Taylor sharing a name with an MP. The PEP flags that remain with a date of birth are office-holders with no date of birth on record, which only a person can rule out.

No. Matching is deterministic fuzzy matching. The same input always produces the same result, which makes it possible to explain and reproduce any decision.
Most false alarms are people who share a name with someone listed. A date of birth separates them: in our benchmark, the share of ordinary names flagged fell from 12% to 6.5% when a date of birth was given, and every listed person was found.
300 real individuals from the OFAC, UK, EU and UN sanctions lists and PEP sources, each written nine realistic ways, and 400 combinations of common UK names, screened against the full live lists using the same pre-filter as production screening. A test fails the build if any figure drops below the floor set from these results.
