None of these. Assume any individual paper is wrong. If it's not your current area of research, you can afford to wait for the results to be reproduced (or disproven, or failed to replicate), and read a meta-study instead. Due to a minefield of mistakes like publication bias and multiple hypotheses, not to mention overt fraud, it seems more likely that an exciting result is wrong than that it's correct.
