- Careful statistical attempts to look for lunar effects over long periods
- generally come up empty-handed.
-
- However, it's not hard to understand how these tales get started. For
- one thing, lighting effects are indeed significant -- the rate of things
- like burglaries really does vary with outdoor illumination. For another,
- the lunar cycle is sufficiently close to an exact number of weeks that
- near-full moons often line up with weekends for several months in a row...
- and all kinds of things, starting with alcohol consumption and proceeding
- from there to automobile accidents and hospital admissions, show quite
- strong 7-day cycles. Finally, there is a well-known and well-understood
- human tendency to remember the unusual and forget the mundane. Yes, odd
- things sometimes happen at the full moon... but to draw any meaningful
- conclusions from this, you have to figure in the times when odd things
- happened without a full moon, or the times when nothing noteworthy happened
- during a full moon. Coincidences do happen; to establish correlation, you
- have to look at the non-coincidences too.
