How might dowsing be based on faulty reasoning?

Dowsing may be based on faulty reasoning because it often relies on confirmation bias, where practitioners remember successful finds while disregarding failures. Additionally, the ideomotor effect can lead individuals to unconsciously move their dowsing tools in response to their expectations, rather than any actual detection of water or minerals. Scientific studies have consistently shown that dowsing lacks empirical support, suggesting that any perceived success is more likely coincidental than a result of any genuine ability.
