The Google Effect
Sparrow, Liu, and Wegner's 2011 finding that anticipated external access to information reduces internal encoding — the search engine preempting the reference palace at the level of neural encoding.
In 2011, Betsy Sparrow, Jenny Liu, and Daniel Wegner published in Science a series of experiments documenting what they called the Google effect on memory. Participants who expected to have future access to information through a search engine were significantly less likely to encode that information in memory. They remembered where to find the information — which folder, which search path — but not the information itself. The brain, anticipating reliable external storage, did not bother with internal encoding. The palace of reference knowledge was not merely decayed. In the next generation, it was never built. This represents a more radical form of externalization than simple atrophy: the cognitive architecture preempts its own construction in the presence of a reliable external substitute.

The Sparrow-Liu-Wegner paper mattered because it moved the externalization question from philosophical speculation to measurable cognitive phenomenon. Before 2011, claims about technology's effect on memory were contested on methodological grounds. After 2011, the effect had
