Continuing to pick World Cup matches according to what the countries have done for my career as a scholar. The approach does ok because of a spurious correlation: populous & rich countries are likely to have both (1) good performances in international sports and (2) strong universities.
Here are the June 12 matches:
Switzerland v. Ecuador -- A big thank you to ETH Zurich. Switzerland all the way!
USA v. Sweden -- USA! USA!
Japan v. Cameroon -- I'm still waiting for my invitation to visit Japan. I even published an article about the country with Daniel Yew Mao Lim. And my students put me on an excellent panel with scholars of Japan back in 2011. So, I am with Japan (but only barely).
