Quick Definition: A proclaimed skeptic that fails to meet the definition of skeptic
Pseudoskepticism (or pseudoscepticism) is a term referring to a philosophical or scientific position which appears to be that of skepticism or scientific skepticism but which in reality fails to be so.
In 1987 Marcello Truzzi revived the term specifically for arguments which use scientific-sounding language to disparage or refute given beliefs, theories, or claims, but which in fact fail to follow the precepts of conventional scientific skepticism. He argued that scientific skepticism is agnostic to new ideas, making no claims about them but waiting for them to satisfy a burden of proof before granting them validity. Pseudoskepticism, by contrast, involves “negative hypotheses”—theoretical assertions that some belief, theory, or claim is factually wrong—without satisfying the burden of proof that such negative theoretical assertions would require.
