Betsy Sparrow
Betsy Sparrow is a psychologist, formerly of Columbia University, and the first author of the 2011 Science paper that gave the world the Google effect: the finding that people who expect a fact to be saved for them remember it less well than people who expect it to be erased. It became one of the most quoted results in popular writing about the internet, including in The Shallows. It has since failed to replicate twice. What makes Sparrow's case worth a page of its own is what she did in between the two failures, which is publish suggestions for how the effect ought to be retested, suggestions the second attempt was then built around. That is how the process is supposed to work, and it is rarer than it should be.
Who they are
The 2011 experiments, run with Jing Liu and Daniel Wegner and published in Science, asked what happens to memory when information is reliably retrievable. Participants typed short factual statements into a computer. Some were told the statements would be saved; others were told they would be erased. The group who expected the file to be there afterwards recalled the statements less well. Alongside it sat a priming experiment testing whether difficult general knowledge questions made people think about computers, measured with a Stroop task. The interpretation that travelled was that we are increasingly remembering where to find things rather than the things themselves, and it fitted the mood of 2011 so precisely that it was quoted as established fact almost immediately.
In 2018 it was included in Camerer and colleagues' high-powered preregistered multi-laboratory replication of social science experiments published in Nature and Science between 2010 and 2015. It did not replicate: p = .26 in the first round, p = .45 pooled. Sparrow responded to the replication by specifying what a fair retest would need, which leaves the question open rather than closed.
What happened next is the part worth dwelling on. Rather than leaving the dispute at the level of an objection, Sparrow set out in 2018 what a fair retest of the effect would need to look like. A study team took her up on it. Hesselmann and colleagues (2020), published in PeerJ, was constructed around the original author's own stated conditions for a proper test. It found no conclusive evidence for the effect either.
That sequence is the reason we treat her generously here. Two nulls, one of them built to her own specification, is about as clear an outcome as this kind of argument produces, and it exists only because she made her response testable. A great many disputed findings never get that far, because the dispute stays a matter of opinion about materials and nobody runs the study that would resolve it. Sparrow's result did not survive, and her conduct after it was challenged is a better model than the result would have been.
Where that leaves the Google effect: the strong version, in which the internet has changed what human memory does, cannot be cited as established. It nevertheless is cited that way nearly everywhere, including in Nicholas Carr's The Shallows, where it carries a substantial part of the argument about memory. A weaker and more careful version survives. A 2024 meta-analysis finds a smaller, context-dependent cognitive offloading effect, which is a claim about behaviour in specific circumstances rather than about the reshaping of memory itself.
One more piece of credit belongs here. The 2011 study is habitually called Wegner's study, because Wegner is the famous name on the author list. Sparrow is the first author. Our own files have now caught that same pattern four times, always with the better-known name absorbing the first author's work, and it is worth correcting out loud each time rather than quietly.

Replications of that work, neither by Sparrow:
Camerer, C. F., et al. (2018), "Evaluating the replicability of social science experiments in Nature and Science between 2010 and 2015," Nature Human Behaviour, 2, 637-644. Failed to replicate Sparrow et al.
Hesselmann, F., et al. (2020), "No conclusive evidence that difficult general knowledge questions cause a 'Google Stroop effect'. A replication study," PeerJ, 8:e10325. Built to Sparrow's own suggested improvements, and also null.
Key ideas
The Google effect: information believed to be externally stored is recalled less well than information believed to be lost.
The effect as originally stated has failed two independent tests, including one designed around the original author's own conditions.
A weaker cognitive offloading effect, smaller and dependent on context, survives in later meta-analytic work.
An original author who responds to a failed replication with testable conditions for a fair retest is doing the thing the replication crisis asks for, whichever way the retest then goes.

Nothing confirmed. A search was run and no website or account could be tied to this person with enough certainty to publish. A name match on its own is not evidence, and a wrong link here would be worse than none.
Nothing found. She has left Columbia and appears in no current faculty listing there or elsewhere, her last publications date from the early 2010s, and the only surviving page is a Columbia bio last modified in 2012, which is too stale to record. She is not listed as deceased, so treat that as unknown rather than settled
Checked 2026-09-10. Handles and affiliations go out of date, so treat this block as a snapshot rather than a standing fact.
