The Takeaway

We usually assume false memories come from being lied to or seeing something misleading. But this study found that your brain will create false memories all on its own, simply because a piece of information feels 'socially relevant.'

It means your memory isn't a recording of the truth; it’s a storyteller that prioritizes what it thinks you need to know to fit in. This has huge implications for everything from eyewitness testimony to how we remember conversations with friends. Your brain cares more about being socially savvy than being factually accurate. We are hard-wired to prioritize social stories over the truth.

From the abstract

Memory is shaped not only by the information itself but also by its social relevance. The present study investigated whether, in the absence of misleading information, social relevance can increase false memory by altering encoding processes, and whether this effect depends on sensory modality. Using a social DRM paradigm combined with fNIRS, we manipulated item relevance (self-relevant, partner-relevant, irrelevant) and encoding modality (visual, auditory). Behavioral results showed that partne
