The same rubric, side by side. A comparison of claim support—not a contest between fields.
| Criterion | GW150914: a discovery that survived scrutiny |
|---|---|
| Overall claim grade | A 96/100 |
| Claim examined | The September 14, 2015 signal recorded by the two Advanced LIGO detectors was gravitational radiation from the merger of two stellar-mass black holes. |
| Claim support40% weight | 5/5 The coherent signal and its waveform support the specified astrophysical interpretation. [1, 2] |
| Methods & controls20% weight | 5/5 The search characterized detector noise and used multiple analysis approaches rather than relying on one fitted curve. [2] |
| Independent checks20% weight | 4/5 GW151226 corroborated the phenomenon, but a second event in the same instruments is not a fully independent recreation of GW150914. [3] |
| Transparency10% weight | 5/5 The collaboration released event data, parameter estimates and supporting material for outside analysis. [4] |
| Claim calibration10% weight | 5/5 The paper reported uncertainty intervals and a conditional noise significance, with a narrowly framed discovery claim. [1] |
| Evidence status | Corroborated |
