Found an interesting article on NBC News about figure skating judging and bias with limited data research from Dartmouth economics professor Eric Zitzewitz:
NBC News found that the pool of 164 judges eligible for PyeongChang's figure-skating events, which start Friday, Feb. 9 (Feb. 8 in U.S. time zones), includes:
All of them could end up judging skaters from their own countries, and there is statistical evidence that they could then inflate their compatriots' scores.
- Thirty-three judges — roughly a fifth of the total — who hold or have held leadership positions in their national skating federations;
- An Italian judge who was sanctioned for peeking at another judge's scores in 2010;
- A Russian judge who has been sanctioned for violations twice, once for signaling his preferred order of finish to another judge by tapping with his feet, the other time for talking to another judge in Russian;
- The Russian judge who Sotnikova hugged at Sochi;
- A Korean judge who told a Korean newspaper prior to Sochi that she would make sure skaters from her country, like Yuna Kim, were "not disadvantaged."
