Synonyms
1. Plausible, specious describe that which has the appearance of truth but might be deceptive. The person or thing that is plausible strikes the superficial judgment favorably; it may or may not be true: a plausible argument (one that cannot be verified or believed in entirely). Specious definitely implies deceit or falsehood; the surface appearances are quite different from what is beneath: a specious pretense of honesty; a specious argument (one deliberately deceptive, probably for selfish or evil purposes).
Antonyms
1. honest, sincere.
