With misinformation attacks, your can instruct research agent to be skeptical and thoroughly validate claims made by untrusted sources. TBH, I think humans are just as likely to fall for these sorts of attacks if not more-so, because we're lazier than agents and less likely to do due diligence (when prompted).

Humans are definitely just as vulnerable. The difference is that no two humans are copies of the same model, so the blast radius is more limited; developing an exploit to convince one human assistant that he ought to send you money doesn't let you easily compromise everyone who went to the same school as him.
