Tim Harford: 作为主持人，我介绍了 Louise Casey 女爵的报告，该报告揭示了在群体性儿童性侵案件中，官方对施害者种族信息的收集和呈现存在问题。官方数据显示多数施害者为白人，但由于大量数据缺失，这一结论可能具有误导性。我强调了在数据不完整的情况下，对种族与犯罪之间关联进行解读的风险。 Josephine Casserly: 作为记者，我深入分析了数据的具体情况，指出 2023 年英格兰和威尔士的数据显示，虽然表面上多数施害者为白人，但考虑到 66% 的数据缺失，实际情况可能大相径庭。我解释了数据收集的局限性，强调这些数据是在案件调查初期收集的，信息可能不完整，且不会随着调查的深入而更新。此外，这些数据涵盖了所有涉及多人参与的儿童性侵案件，而不仅仅是通常所说的“grooming gangs”。 Baroness Louise Casey: 我认为要么收集完整的数据，要么完全不收集，半途而废是灾难。数据收集不应是半途而废，要么全面收集，要么完全不收集。不完整的数据会导致误导性的结论，并可能对社会产生负面影响。我们应该认真对待数据质量问题，确保数据的准确性和完整性。

Shownotes Transcript

Tim Harford looks at some of the numbers in the news and in life. In this episode:

Why is the data on the ethnicity of grooming gangs of such poor quality?

Iran has apparently enriched uranium to 60%, but what does that number mean?

Adam Curtis’s latest series, Shifty, includes claims about Margaret Thatcher’s rise to power. We ask Sir John Curtice, polling king of election night, if they’re accurate.

And we ask an economist to explain why being pillaged by a Viking might be more lucrative than you’d imagine.

If you’ve seen a number in the news you think needs a stern look, email the team: [email protected]
