What star ratings are most effective?

I couldn't find specific details in the retrieved data about the effectiveness of star ratings. Shane Parrish might not have extensively discussed this particular topic.

If you're looking for deeper insights into decision-making and review systems, I recommend exploring more of Shane Parrish's work on Farnam Street, where he often delves into how people make decisions and evaluate information. If you have any other questions or a different topic you'd like to explore, please let me know!
