The researchers used published fMRI results, and along the way they swipe the fMRI community for their “lamentable archiving and data-sharing practices” that prevent most of the discipline's body of work being re-analysed.
So the raw data isn't being saved so that someone else can independently verify the results. No checking the computers math, no checking the researchers settings on the machine. Just blanket trust for the people and the machine, and purging of any way of poking holes in someones findings. Even if this wasn't caused by a software bug the lack of archiving the raw dataset so that it can be rerun when software improvements are made is just infuriating.
"Spock, did you see the looks on their faces?" "Yes, Captain, a sort of vacant contentment."
