Abstract: In the age of rapid development of technology, the massive amount of information on the Internet gives users more browsing options. However, algorithms, based on big data, which canse a series of negative consequences of one-sided unliberated phenomena in people's social life, have plunged users into the "information cocoons" during their browsing time. According to Marx's theory on the universal liberation of human beings, and based on the analysis of the causes of "information cocoons", this paper observes the problems of unequal information dissemination and loss of social stickiness caused by "information cocoons", and puts forward the liberation path. In today's era when people are increasingly dependent on technology, this paper puts forward the importance and thinking of value rationality, and also some suggestions that Marxist theory should be actively supplemented in the process of breaking the shackles of "information cocoons".
