使用する際の注意点

Although dubious is largely synonymous with doubtful, there is a notable difference when describing statements or facts: dubious is used when the statement is a cause of doubt, while doubtful is used when a fact is in doubt. For example, “the company’s earnings report was dubious” (questionable) versus “his chances for recovery are doubtful” (uncertain or unlikely). See also doubtable § Usage notes.
