You can read the review in the print edition and I did have the full text posted here but the good folks at the magazine have also put it online to read in full, so do check it out at the link below.
Mind Change marshals many published sources to address these claims. However, this provides little scientific insight owing to Greenfield’s difficulty with synthesising the evidence in any meaningful sense, while she also makes some glaring mistakes in her interpretation of it. Although she makes much of her use of peer-reviewed evidence, surveys done by companies for marketing campaigns are often given the same weight as scientific studies and opinions from self-appointed pundits as those of specialists.
As an end-note, what’s most interesting is that Greenfield is essentially making an argument about public health but doesn’t really have the conceptual tools to do so and consequently doesn’t seem to understand how, and how strongly, to draw real world inferences from different types of evidence.
However, in terms of Greenfield’s evolution, she is at least tackling some of the relevant evidence, but this really isn’t up to a standard that merits any of the media attention it gets.
