The battle for our Attention?

WIKIPEDIA: Attention is the behavioral and cognitive process of selectively concentrating on a discrete aspect of information, whether considered subjective or objective, while ignoring other perceivable information. William James (1890) wrote that "Attention is the taking possession by the mind, in clear and vivid form, of one out of what seem several simultaneously possible objects or trains of thought. Focalization, concentration, of consciousness are of its essence."^[1] Attention has also been described as the allocation of limited cognitive processing resources.^[2] 

Attention is manifested by an attentional bottleneck, in terms of the amount of data the brain can process each second

The weapon of spiritual warfare against attention is "distraction"...
