I will suppose...that some malignant demon, who is at once exceedingly potent and deceitful, has employed all his artifice to deceive me;
I will suppose that the sky, the air, the earth, colors, figures, sounds, and all external things, are nothing better than the illusions of dreams
A new bogeyman now haunts our dreams, our courts, our civic discourse. At your every turn, its threat compels you to look over your shoulder, checking and checking again whether your decision was made under its nefarious influence. Words which would have before passed innocently by now demand critical scrutiny, to be tested for any trace of the impurity. Worse, even when no trace can be found there is no relief – it only means the menace has burrowed deep beneath your ability to detect it.
The phantom of "unconscious bias" is here, inside your mind.
