Skepsis organizes public lectures and publishes articles and books related to skepticism, including a quarterly magazine Skeptikko.
Skepsis is known for its annual Huuhaa ("humbug") Prize which is awarded to a person or an organization that has diligently promoted pseudo- or fringe science, and for its Socrates Prize which is awarded for work promoting Socratic, rational thinking.
Skepsis also offers a prize of €10,000, sponsored by the astronomer Hannu Karttunen and the magician Iiro Seppänen, to anybody in Finland who can produce paranormal phenomena under satisfactory observing conditions.
The same sum is also offered as an ET scholarship to anyone who can prove that she/he/it is an extraterrestrial by providing a DNA (or equivalent) sample for investigation.
