The whole thing is ridiculous.
The primary ridiculous fact that it's OK to say genocide against Jews is OK depending on the circumstances, but not OK to omit quotation marks around some non-substantive descriptive passages copied from other academic works. But that's old news now.
But then there's the secondarily ridiculous fact that some news outlet is trying to pull the same trick on the wife of one of the guys responsible for the original plagiarism issue.
I mean yeah, great, let's hold highly-paid superstar academics to high standards. If these examples are really on par with what Gay did, and with what would get a student kicked out of Harvard, then yes, anyone who wrote something like this should face consequences.
But is that really what's going on? Does the Business Insider editorial board all of a sudden care so deeply about academic honesty?
What's actually bad is that "Business Insider" themselves did this investigation. Compare the breathless hysteria of this announcement to the careful and sober work done by Data Colada on the work of Gino and Ariely.
None of which ever really challenged her work overall or conclusions or points she substantiated. Which should be the total point.
