We live in an information environment - that is, the level and type of text, images, media, etc. available to us each day. The books on "information seeking" and decision making are pointing to a new dynamic. As one of the pioneers in information theory, Herbert Simon, pointed out long ago, "a wealth of information creates a poverty of attention." With too much information at our fingertips, we tend to drown in the volume and not pay attention to the important. We need to turn on and turn off the flow.
I like what one writer about decision making said should be the sequence. Ask ourselves and others to: 1. tell me what you know; then 2. tell me what you don't know; and finally 3. tell me what you think. Having access to the flow does not make us experts. If we are awash in data and get anxious without the radio, tv, internet, blogs, twitter messages running -- then our brain's capacity is exceeded. Extra information can lead to worse decisions.
