As a rule this sort of fraud isn't. If the result is important, people will try to do work based on it and sooner or later figure out that the foundation is rotten and why. Most of the time the work isn't important, except to the "scientist" himself in accumulating published papers ("publish or perish"). This is one of the reasons there's no need to directly double check every scientific conclusion, instead you tend…

I disagree with your assertion, due to the consequence of a similar series of faked results first reported on earlier this week. Essentially, people wasted 2 months of distributed computing time trying to use the data from a fake crystal structure. Unsurprisingly, these were unsuccessful. Hundreds of thousands of compute hours were wasted and people were diverted from making real discoveries because the structure was…

I've wasted 2 months of distributed computing time on just bad assumptions made by mistakes I made, so as noted below, in the big picture, that's a relatively minor loss. Does it set back science. Of course, but is it catastrophic, no.

As someone pointed out above, in fields where you collection and analysis times are measured in years if not decades you could run into trouble, but for chemistry and biology where you are at significantly shorter collection timescales, it isn't that big of an issie

a similar series of faked results first reported on earlier this week Wait, is this a separate scandal? What's with all this bogus crystallography?

A crystallographic paper is more or less just a structure determination in a common file format (CIF - the article talks about it). There's very little in the way of interpretation. As such, they're way easier to falsify than papers in even really closely related fields. I've spent plenty of time pulling structures from ICSD and other databases populated off Acta Cryst; my PhD was in computational mineralogy - but a…
