Artificial Intelligence promises to create vast enhancement in products and services, from smarter and cheaper algorithmic financial advisors, to self-driving that surpass human driver safety. Yet, people often mistrust new technologies, due to a variety of psychological and cultural reasons. Furthermore, introducing AI often alters the tradeoffs involved—e.g. increase speed but reducing accuracy. This project tries to identify the causes of trust in, and aversion to, AI products. We explore when fears by consumers and citizens are warranted, and what tradeoffs different stakeholders are willing to accept. We identify how to overcome excessive trust or irrational aversion to AI-driven decision-making in consumer products and government services.
