There is no empirical or scientific evidence to support the existence of supernatural powers attributed to witchcraft, such as casting curses, flying, or altering physical reality through magical means.

Despite extensive historical accounts and cultural beliefs in the efficacy of witchcraft, no controlled scientific study has ever demonstrated the ability of individuals to perform supernatural feats associated with traditional witchcraft, such as levitation, telekinesis, causing illness or death through curses, or manipulating weather through magic. The scientific method relies on testable, repeatable observations and measurable outcomes, and claims of supernatural phenomena consistently fail to meet these criteria. When alleged magical effects are investigated, they are typically found to be attributable to coincidence, psychological suggestion (e.g., placebo or nocebo effects), misinterpretation of natural events, or outright fraud. The absence of verifiable evidence for supernatural witchcraft does not negate the historical, cultural, or psychological 'reality' of the belief in it, but it firmly positions such claims outside the realm of scientific validation.
