Wood can conduct enough electricity to deliver a shock when damp
Scientific literature confirms that wood is a semi-conductive material whose electrical resistance decreases significantly as its moisture content increases, meaning damp wood can indeed conduct electricity.
The retrieved papers examine the electrical properties of wood, consistently showing that electrical resistance drops and conductivity rises when moisture content increases. While none explicitly focus on delivering lethal shocks to humans, the empirical fact that damp wood conducts electricity well enough to alter resistance measurements supports the fundamental premise of the claim.

Kus et al. (2021) demonstrate that wood electrical resistance drops and conductivity increases as moisture content rises, especially above the fiber saturation point.

The study by the same author group in 2025 reiterates that wood acts as a semi-conductive material whose electrical properties are heavily dependent on moisture content.
