We found robust evidence that lower freedom of speech increases conspiracy beliefs.

This effect was consistent across contexts and held even when controlling for perceived levels of democracy, highlighting the specific nature of this relationship.

This trilemma may have detrimental consequences for open science practices, turning them into a form of virtue signalling that compensates for low transparency.

Boycott behaviors may be hard for sports fans to maintain due to the lack of alternative products.

Ultimately, boycott may reflect low fandom rather than high political engagement.

In the end, lasting boycotters may be those uninterested in sports events, making the boycott poorly consequential.

Even more puzzling was the finding that this decrease occurred regardless of French fans' political concerns about minorities and environmental issues—the best predictors of boycott intentions.

In other words, politicized fans struggled to maintain the boycott.

Then, we compared fans' intentions before the WC with their actual boycott behavior after the tournament.

We observed a decrease in all countries, but it was only significant in France—likely due to limited statistical power in other countries and the strong performance of the French team.

We investigated boycott intentions in France, Belgium, Canada, and Switzerland (N = 1,635).

Boycott intentions were tied to concerns about environmental and minority issues.

Rejection of the boycott was best predicted by strong identification with the team and enjoying football’s aesthetic appeal.
