"A Study into Muggle Suspicions about Magic" was a report conducted by a committee of the Ministry of Magic that was headed by Harold James Potter and Phoebus Penrose. It examined some of the ways in which Muggles have noticed things from the wizarding world.
- The crop circles Muggles believe are made by extraterrestrials are actually made by wizards and witches competing in the Contorting Cereals contest of the Annual International Wizard Gardening Competition.
- The UFOs which Muggles spot in the sky are in fact escaped Quaffles.
- The Loch Ness Monster Muggles claim to have seen is a real animal.
