In today’s media-rich world, we are more than used to seeing photographic images that have been tweaked and tampered with, and most people know—at least implicitly—that convincing digital trickeries are easy to produce. Whereas the entertainment value of Photoshopped images is limitless, seeing these images can also have rather more meaningful consequences. Numerous studies published over the past decade have shown that doctored images can change people’s beliefs about major public events, and even about their own personal experiences. In fact, more than this, doctored images can change people’s memories of past events, and can even implant memories of entire events that never occurred at all. In this seminar I will outline a series of studies in which we explored the capacity of fabricated images to alter people’s beliefs and memories. These studies comprise data examining possible boundary conditions of the effect, and also data that begin to tease apart the cognitive mechanisms responsible. With these data in mind, I will discuss the broader question of what the ‘doctored-evidence effect’ teaches us about the (re)construction of autobiographical and episodic memories, and the extent to which belief is necessary for such memories to persist. Finally, I will illustrate some behavioural consequences of falling prey to this trickery.
