Considering the totality of the circumstances, and all relevant factors, the immigration judge may base a credibility determination on the demeanor, candor, or responsiveness of the applicant or witness, the inherent plausibility of the applicant’s or witness’s account, the consistency between the applicant’s or witness’s written and oral statements (whenever made and whether or not under oath, and considering the circumstances under which the statements were made), the internal consistency of each such statement, the consistency of such statements with other evidence of record (including the reports of the Department of State on country conditions), and any inaccuracies or falsehoods in such statements, without regard to whether an inconsistency, inaccuracy, or falsehood goes to the heart of the applicant’s claim, or any other relevant factor. There is no presumption of credibility, however, if no adverse credibility determination is explicitly made, the applicant or witness shall have a rebuttable presumption of credibility on appeal.
