I did my Ph.D in cognitive neuroscience, where I conducted experiments on human subjects. Running these kinds of experiments required approval from an ethics committee, which for all their faults (and there are many), are quite good at catching this kind of shenanigans.
Is there not some sort of equivalent in this field?
It seems they lied to the ethics committee. But I'm not holding my breath for the University to sanction them or withdraw/EoC their papers, because Universities prefer to have these things swept under the carpet.
Depends on the history of UMN CS submissions for ethics review, how they were advised to complete the exemption request, whether they made false statements or omitted something, whether they intended to deceive, etc.
The requirements arising from US Govt grant funding may well be more strict than UMN.
