TWV Podcast Episode 470: New Science on How the Moon Affects Us

This week on The Whole View, we circle back to an older topic in order to review the updated science exploring whether the moon affects us humans. We discuss the latest studies investigating how the moon may influence our behavioral and biological functions such as sleep, menstrual cycles, and mental illness. If you have been here for a while, you know that Stacy and I have very differing viewpoints on this topic, and this podcast is no different!

While Stacy may have been hoping (again) for a causal link, I dive into some interesting considerations with statistics as a whole and how they are often not intuitive, and require certain techniques to validate that any research outcomes have not simply happened by chance. Tune in to the podcast to learn about the interesting probability case study “The Birthday Problem” and the statistical anomalies it reveals.

Throughout this entertaining dialogue between Stacy and I, we ultimately agree that it comes down to this: science has not provided any convincing proof of a causal link between our human functions with the gravitational effects of the moon cycles.
