Knowing about your biases does not automatically make you immune to them, and saying “but I told them the bias I was exploiting” doesn’t excuse you from responsibility for knowingly exploiting a bias.
I didn’t claim automatic immunity, I said “can”. While deontologists might object to “knowingly exploiting a bias” full stop and virtue ethicists might claim that a person who does such things is probably vicious, a consequentialist must determine whether, in this case, using the Dark Arts might lead to better or worse outcomes (which seems non-obvious to me).
