The Information Age – the revolution in collecting and disseminating information made possible by computers, the internet, email, mobile phones, and digital media - is the main force now shaping the evolution of human society. Unfortunately, a great deal of the information is irrelevant or suspect, and the sheer amount of it is drowning us. We've seen an explosion in irrelevant, unclear, and simply erroneous data fragments. This overabundance of low quality information has been called "data smog." The inability to process this excessive information can make people feel less in control of their lives. That feeling and an associated sense of helplessness are strongly correlated with both depression and anxiety.
