Does the fact that two phenomena occur at the same time imply that one is the cause of the other? How to interpret this simultaneity, which economists, in particular, call a correlation? This is what a statistician explains to his cat Albert in this short video.

If the countries where the inhabitants consume the most chocolate are also those that count the most Nobel prizes, does eating chocolate make us all the more intelligent? The statistician points out that any correlation does not reflect a causal relationship. He warns against hasty conclusions and invites readers to use their judgment when reading the press or scientific publications.
