If you look at the mathematical achievements of frontier models recently, their strength has been to bring in information from a vast array of sources and to consider them within the context of each other.
I anticipate that it won't be long before this ability to look into every nook and cranny with be able to identify academic fraud. Identifying every piece of academic fraud to date would probably come soon after.
It wouldn't take much to extend that ability to identify deliberate misinformation. That's in the future, but it looms close enough on the horizon that you would have to be a fool to create an evidence record like this in and attempt to trick the models of today.
