A serious claim looks like: name N’s count in office O, year Y, rose after event E, and similar names without E did not.
Most dinner-party claims skip the last clause. Lieberson lives in that clause.
Findings
- Lieberson — Stars are over-credited
Internal fashion (endings, distinction) explains movements that look like copycat fame.
- Social Security Administration — Visible post-media jumps
Some rare names show step-changes after a film or series year — inspect the actual year rows.
- Office for National Statistics — UK-jurisdiction media events
Royal and screen names can move E&W lists in dated releases — still not a world cup.
- Statistics Korea — Keep the file Korean
Export fame ≠ automatic domestic frequency change; check the year.
- Bertrand & Mullainathan — Fame does not cancel bias
A trendy celebrity name can still be stereotyped in a résumé stack.
- Brand/celebrity studies — Attention is short
Many spikes fade within a few cohorts — historical pattern, not a prediction of next year’s star.
Mechanisms
- Attention shock — A name enters many ears in one season.
- Character detachment — Fans file a fictional string as a legal given name.
- Class filter — Some fame reads as “too much” for a birth certificate.
- Neighbour riding — A star name pulls lookalikes — Lieberson’s cluster again.
Debates
- Are character names unfair to the child? — Association risk vs. parental art. A values fight, not a statute in most places (some registrars balk at trademarks).
- Does refusing celebrity names mean good taste? — It means a taste. Lieberson would not give you a medal.
- National file vs global fame — A worldwide show, a local registrar — mismatched scales.
Celebrity is a hypothesis about a curve. Test it with a dated file.
