"As far as I can tell, the BICEP2 scientists haven’t suffered much professionally from the fiasco. When David Spergel talked here at Columbia about the subject, he noted that this hadn’t stopped the PI, John Kovac, from getting tenure at Harvard. In the book, Keating mentions some “embarrassment and guilt”, but no negative professional consequences"
In the long run, it is good for society if researchers can make mistakes and keep their careers.
In the long run, it is good for society if journalists are sometimes embarrassed by reporting on a story when they don't have access to the data behind the story.
So in the long run, it is probably for the best that these researchers suffered no adverse effects. If anyone changes their behavior, I'd rather it be the journalists. They should not give too much publicity to teams making big announcements while hiding their data.
