During the World Series, Google ran an ad for Gemini noting several correlations between home runs and full moons, FlowingData reported. Marcos Huerta analyzed data on full moons and home runs to debunk each statement, according to the article. The ad included 3 stats that are all a little true if you ignore the error bars, and the home run stat in particular has some enormous error bars, the article said. The piece suggested this resembles what might happen if an LLM is asked to do data analysis without careful supervision, describing it as “Agentic p-hacking?” while noting it is not really p-hacking since it still could not find a statistically significant result. The article characterized the ad as “Just fluffy marketing and not much else.”
