Current and popular are not necessarily characteristics that make a source credible. A credible source should be accurate and believable, as it should have evidence-based information that can be verified. Famous and original does not automatically make a source credible either. Biased and persuasive are actually qualities that undermine the credibility of a source, as bias can indicate a lack of objectivity and persuasion can indicate an attempt to manipulate the audience rather than provide objective information.
