This, ultimately, is why yesterday’s keynote was so disappointing. Last year, before Facebook realized it could just leverage its network to squash Snap, Mark Zuckerberg spent most of his presentation laying out a long-term vision for all the areas in which Facebook wanted to innovate. This year couldn’t have been more different: there was no vision, just the wholesale adoption of Snap’s, plus a whole bunch of tech demos that never bothered to tell a story of why they actually mattered for Facebook’s users. It will work, at least for a while, but make no mistake, Facebook is the only winner.
But it may not take coercive suggestion to affect a person’s memories. The testimony of eyewitnesses is notoriously subject to suggestion and to error, frequently with dire effects on the wrongfully accused. 6 With the advent of DNA testing, it is now possible to find, in many cases, an objective corroboration or refutation of such testimony, and Schacter notes that “a recent analysis of forty cases in which DNA evidence established the innocence of wrongly imprisoned individuals revealed that thirty-six of them (90 percent) involved mistaken eyewitness identification.”
