This is an era of fragmented information overload, where people seem to be gaining more and more information and expanding their cognitive space, but in reality, they are increasingly living in islands of information. In an era of underdeveloped information, people struggled to obtain the truth. In the age of information explosion, people only believe in truths that align with their own values.
The increasing amount of information does not bring about rational understanding, peaceful discussions, or self-awareness through self-examination. In this "post-truth era," people only retain information fragments that are compatible with their existing knowledge. The more they retain, the more "confident" they become. The more homogeneous the content, the more biased they become. People are not becoming smarter in the wave of information, but rather they appear smart on the surface while becoming increasingly foolish in reality. In the polarization of thoughts, different groups of people are swayed by emotions and biases, making rational dialogue increasingly difficult, and social cognition is continuously heading towards fragmentation.
