When we are told that a prediction is from an automated system, most people are more likely to believe it and not subject it to the same skepticism and critical thinking that we do to predictions from humans. Even if there is a human-in-the-loop system that requires a human to confirm it, that's often just laundering the machine's prediction through a human. When we are primed by being told this is what The System predicted, we're more likely to override our normal processes. This is especially the case when The System has worked 99% of the time --- which is still a lot of false positives.
Although this can also be the case with priming from predictions or judgments by other humans. The Asch conformity experiments involved planting fake test subjects in a group activity where subjects had to give answers to a very obvious perception question, and the real test subject could hear everyone else's answers. The fake subjects went first and all gave the blatantly wrong answer. The percent of people who conform varies with how you run the experiment, but typically a majority of the subjects end up giving the obvious wrong answer that everyone else did: https://en.wikipedia.org/wiki/Asch_conformity_experiments
