ASSESSMENT SCOPEWhat this score covers
All included contribution titles and notes are available in English. The complete original text remains available in Chinese; both editions use the same scores and source links.
Uncovered contributions and unresolved harms are not treated as zero. This is not a complete assessment of a lifetime.
2 included contributions have incomplete evidence; the relevant gap appears with that contribution.
Original scope note
This research record currently includes 2 outcomes within a limited scope; M and attribution shares are revisable judgments. Uncovered content and negative effects not yet clarified are not treated as zero; specific gaps appear in the item-by-item explanations.
Original Chinese scope
本轮当前已列2项有限研究账；M与归功份额为可修订判断。未覆盖内容和未核清的负面作用不按零处理，具体缺口见逐项说明。
CALCULATIONHow the score is calculated
Q = 10^(M/2) − 1; Lᵢ = aᵢ × Qᵢ; L = Σ Lᵢ; S = 2 × log₁₀(1 + L).
M is an outcome’s assessed magnitude and a is the person’s allocated share. A standalone score is only a per-item reference; the attributed light from distinct contributions is what can be combined.
SCORE DETAILS
