Here’s a tiny little window into Brazil thanks to our friends at Itau.

Like Goldman Sachs and Bloomberg, Brazil’s largest private bank did a statistical analysis of who will win the World Cup. Unlike Goldman Sachs and Bloomberg, they refused to reveal the results of their statistical analysis, which is hilarious given that they sent it to every journalist in the country.

Why the reticence?

Is it a lack of transparency and accountability? Very possibly. The bank is notorious for treating clients poorly (as I blogged about here), going as far as making it impossible to call branches to talk to account managers or staff.

Lack of confidence in their results? Unlikely. Their partial predictions (why reveal half your results?) were hardly controversial. They boldly predicted the semi-finals will feature Spain, Germany, Brazil and Argentina.

A desire not to offend? Most likely. In bars and in foreign policy and in everything in between, Brazilians are averse to giving strong opinions with strangers lest they hurt someone’s feeling.

My prediction? Like Goldman and Bloomberg, I go for Brazil. But it’s a funny old game. Anything can happen. Roll on June 12.
