"We are more wired than ever before, and as a result need to be more mindful of managing email or it will end up managing us."[30]

The Daily Telegraph quoted Nicholas Carr, former executive editor of the Harvard Business Review and the author of The Shallows: What The Internet Is Doing To Our Brains, as saying that email exploits a basic human instinct to search for new information, causing people to become addicted to "mindlessly pressing levers in the hope of receiving a pellet of social or intellectual nourishment". His concern is shared by Eric Schmidt, chief executive of Google, who stated that "instantaneous devices" and the abundance of information people are exposed to through e-mail and other technology-based sources could be having an impact on the thought process, obstructing deep thinking, understanding, impedes the formation of memories and makes learning more difficult. This condition of "cognitive overload" results in diminished information retaining ability and failing to connect remembrances to experiences stored in the long-term memory, leaving thoughts "thin and scattered".[31] This is also manifest in the education process.[32]
