The authors appeared increasingly ambivalent about the social implications of their work. On the one hand, they announced that these new predictive capabilities could be used to “improve numerous products and services.” They concluded that online businesses can adjust their behavior to match each user’s personality, with marketing and product recommendations psychologically tailored to each individual. But the authors also warned that automated prediction engines run by companies, governments, or Facebook itself can compute millions of profiles without individual consent or awareness, discovering facts “that an individual may not have intended to share.” The researchers cautioned that “one can imagine situations in which such predictions, even if incorrect, could pose a threat to an individual’s well-being, freedom, or even life.”
