Why Did Artificial Intelligence Fail in the FIFA World Cup 2018?

There are different approaches to predict the results of FIFA World Cup. One approach is to simulate every single match in a paired comparison in terms of team's capabilities and the winning odds. Zeileis, Leitner, and Hornik (2018) used the same technique, and they predicted that Brazil would win the FIFA World Cup 2018 with a probability of 16.6%, and it is followed by Germany (15.8%) and Spain (12.5%) [1]. Swiss Bank UBS also predicted the same three teams as the top 3 teams but in a different order. They predicted Germany (24.0%) as the champion, followed by Brazil (19.80%) and Spain (16.1%).
