Doug Bower and Dave Chorley tricked the world into believing crop circles were made by mysterious forces, starting in 1978. They revealed the hoax in 1991 after many theories, including one published in Nature, suggested otherworldly causes.

Infact verdict: True (87/100).

The claims regarding Doug Bower and Dave Chorley's involvement in creating crop circles and their subsequent confession in 1991 are well-documented and supported by multiple credible sources.

Overall, the claims are factual, with strong historical evidence supporting them.
