Bluff and spin
9.8 + 12.5 = 22.3Bluff20%Spin25%
Bluff counts claims that do not hold up. Spin counts questions not answered straight. Each is out of 50, and together they make the BS Index.
How the number is built
9.8 + 12.5 = 22.3Bluff = 50 × (1 − Accuracy 80%) = 9.9
Spin = 50 × (1 − Answers questions 75%) = 12.5
BS Index = Bluff + Spin = 22.3 → shown as 22
The same fixed weights for everyone. Consistency and Substance are shown alongside, never in the number.
