Static electricity can cause discomfort and minor shocks that may startle or cause reflexive reactions, but it rarely causes serious physical harm under normal circumstances.

Key Evidence
Static shocks deliver high voltage but very low current, making them generally harmless to humans.

Most injuries related to static shocks come from reflexive reactions rather than the shock itself.

Static electricity can damage electronic components and cause fires in hazardous environments but rarely causes direct physical harm to people.

What the Evidence Shows
Static electricity is the buildup of electrical charge on the surface of objects, which can discharge suddenly and cause a shock. While these shocks can be surprising and sometimes painful, they generally do not cause significant injury to humans. The voltage involved in static shocks can be quite high (often thousands of volts), but the current (amperage) is extremely low, which limits the potential for harm.
However, there are some important nuances:
Static shocks can cause involuntary reflexes that might lead to secondary injuries, such as falling or dropping objects.
In sensitive environments like electronics manufacturing, static discharges can damage components, which is a different kind of 'harm.'
In rare cases involving flammable gases or dust, static discharge can ignite fires or explosions.
For everyday human experience, static electricity is mostly a nuisance rather than a danger. It can hurt in the sense of causing a sudden shock or discomfort but does not typically cause lasting physical injury.
Therefore, the statement "Static can hurt you" is mostly true if interpreted as causing minor pain or discomfort but misleading if taken to imply serious injury is common.
