Kaidah Sagan

Kaidah Sagan adalah sebuah neologisme yang merujuk pada pepatah bahwa "klaim luar biasa memerlukan bukti luar biasa", "extraordinary claims require extraordinary evidence" (ECREE).^[1] Julukan pepatah ini diambil dari nama astronom Carl Sagan, yang memperkenalkan frasa ini di program televisinya, Cosmos. Kaidah tersebut menggambarkan prinsip inti dari metode ilmiah dan skeptisisme, serta dapat digunakan untuk menilai keabsahan suatu klaim.

Pernyataan yang serupa sebelumnya pernah dinyatakan oleh tokoh-tokoh seperti Théodore Flournoy pada tahun 1899, Pierre-Simon Laplace pada tahun 1814, dan Thomas Jefferson pada tahun 1808.
