A pejorative form of neo-logical positivism that maintains that the only way to acquire knowledge is by the scientific method even to the exclusion of all other forms of knowledge acquisition such as empiricism and rationalism.

No members in the GDC exposes position to the best of our knowledge... but we have yet to use the scientific method to test this.

As a pejorative, Scientism is frequently misused, but applicable to much of the skeptic community.
