Hitching has written on earth mysteries, dowsing, paranormal and ley lines. In his book Pendulum: the psi connection (1977) he came to the conclusion that dowsing is genuine, he listed a number of alternative explanations such as electromagnetism and psychic ability which he thought were associated with dowsing. Stuart Fleming in the New Scientist gave Hitching's book Earth magic (1978) a positive review; the book linked many of the megaliths around Europe to groups of men whom he called "megalithic mathematicians" who - according to Hitching - could connect with a spiritual energy from the universe.
Hitching also wrote The world atlas of mysteries (1981); an atlas which listed many earth mysteries from around the world. The book was criticised in the New Scientist for some of his conclusions such as linking animal extinctions to reversals in the earth's magnetic field.
Hitching is a non-Darwinian evolutionist. He wrote the book The Neck of the Giraffe or Where Darwin Went Wrong (1983) in which he criticised both creationism and Darwinism, instead supporting a form of Neo-Lamarckism.
