“Lightning never strikes the same place twice.”

The idea that lightning never strikes the same place twice is a widely used idiom, often meant to suggest that a rare or unfortunate event is unlikely to reoccur. This metaphorical usage has likely contributed to its popular acceptance as a literal truth. However, from a scientific perspective, this common saying is entirely false.

In reality, lightning frequently strikes the same locations multiple times, especially objects that offer an easy and direct path for electrical discharge. Lightning, being a powerful electrical current, seeks the path of least resistance between charged storm clouds and the ground. Tall, isolated structures such as skyscrapers, radio towers, and mountain peaks act as natural "preferential strike points" because they significantly reduce the distance lightning needs to travel. The Empire State Building in New York City is a prime example, experiencing dozens of lightning strikes each year, sometimes multiple times within a single storm.

The persistence of this misconception may stem from a combination of factors. For a vast, flat, and unremarkable patch of ground, the statistical probability of being struck twice by lightning within a short timeframe is indeed very low, which might lead to the casual observation supporting the myth for everyday locations. Additionally, the idiom's long history as a figure of speech has embedded it deeply in our culture, making it difficult to dislodge despite clear scientific evidence to the contrary. However, physics dictates that if a location provides the most efficient channel for electricity, lightning will repeatedly choose that path.
