Abstract: All-round changes are brought to a society by the intellectualization of the information society， and new challenges are also posed on the studies of collective responsibility. Analyzing the root of the challenges faced by collective responsibility involves the bearers of moral responsibility， the attribution of responsibility， the norms of responsibility and the distribution of responsibility. The “mindless” challenge of collective responsibility subjects， i.e.， the ontological reconstruction of people and intelligent technology with information produces mindless agents; the cognitive responsibility challenge from responsibility attribution and responsibility norm change， i.e.， the hyperconnectivity of information is further improved， and the collective must bear cognitive responsibility and cannot be exempted; the challenge of information power to the collective responsibility structure， i.e.， intelligent technology has brought a more hidden form of power， which requires the structure of collective responsibility for further analysis; the challenge of distributed morality governance， i.e.， intelligent technology makes distributed morality more extensive， but the governance path is not clear. These challenges not only reflect the new demands for collective responsibility research in an intelligent society， but also demand changes in the basic framework of ethics.

Key words: intelligent information society; collective responsibility; man-machine responsibility; artificial intelligence ethics
