Explore a 20-minute conference talk from the Models of Consciousness Conferences examining the concept of negative indicators for detecting consciousness in artificial systems. Learn about probability-raising indicators and their role in determining consciousness, while diving into two distinct types of negative indicators - indirect and direct. Understand how indirect negative indicators influence the effectiveness of other consciousness indicators, and discover how direct negative indicators can independently lower the probability of consciousness in artificial systems, regardless of other present factors. Gain insights into the challenges of assessing consciousness in artificial systems in the absence of empirically confirmed theories.
