Specious
adjective /ˈspiːʃəs/ — Superficially plausible but actually wrong.
Definition
Appearing correct or logical on the surface, but actually false or flawed — misleadingly attractive in appearance.
Beyond the definition
Specious is the word for arguments that almost work — that have the shape of reason without its substance. The danger of specious reasoning is that it's flattering: it looks intelligent, sounds careful, and isn't.
Origin & history
From Latin speciosus (good-looking, plausible), from species (appearance). Originally meant beautiful or impressive in appearance. By the 17th century, the ironic sense had taken over: looking good while being wrong.

Specious vs fallacious
Fallacious simply means logically incorrect — an argument that contains a flaw in its reasoning, regardless of how it appears. Specious is more insidious: it means appearing correct or sound while actually being flawed — the problem is its plausibility, not just its wrongness. A fallacious argument is wrong; a specious one is dangerously convincing. You might catch a fallacious argument on first read; a specious one requires more careful examination.
