We are far more likely to remember previously presented news that were reported to be certain as mere speculations than to remember explicit speculations as facts

Abstract: Modern media report news remarkably fast, often before the information is confirmed. This general tendency is even more pronounced in times of an increasing demand for information, such as during pressing natural phenomena or the pandemic spreading of diseases. Yet, even if early reports correctly identify their content as speculative (rather than factual), recipients may not adequately consider the preliminary nature of such information. Theories on language processing suggest that understanding a speculation requires its reconstruction as a factual assertion first—which can later be erroneously remembered. This would lead to a bias to remember and treat speculations as if they were factual, rather than falling for the reverse mistake. In six experiments, however, we demonstrate the opposite pattern. Participants read news headlines with explanations for distinct events either in form of a fact or a speculation (as still being investigated). Both kinds of framings increased participants’ belief in the correctness of the respective explanations to an equal extent (relative to receiving no explanation). Importantly, however, this effect was not mainly driven by a neglect of uncertainty cues (as present in speculations). In contrast, our memory experiments (recognition and cued recall) revealed a reverse distortion: a bias to falsely remember and treat a presented “fact” as if it were merely speculative. Based on these surprising results, we outline new theoretical accounts on the processing of (un)certainty cues which incorporate their broader context. Particularly, we propose that facts in the news might be remembered differently once they are presented among speculations.
