The brain has an attentional mode called the "mind wandering mode" that was only recently identified. This is when thoughts move seamlessly from one to another, often to unrelated thoughts, without you controlling where they go. This brain state acts as a neural reset button, allowing us to come back to our work with a refreshed perspective. Different people find they enter this mode in different ways: reading, a walk in nature, looking at art, meditating, and napping. A 15-minute nap can produce the equivalent of a 10-point boost in IQ.

We really are living in an age of information overload. Google estimates that there are 300 exabytes (300 followed by 18 zeros) of human-made information in the world today. Only four years ago there were just 30 exabytes. We've created more information in the past few years than in all of human history before us.

I think, though, that we need to be armed with the critical thinking skills that lawyers and scientists and journalists such as yourself have. We all need to have those as we make our way through the day. And they're not that hard to acquire.

The most important, the longest lasting, the strongest emotional, and the most practiced memories are the ones that are embedded the deepest in the brain, and because we have retrieved them so many times previously, they are the most able to be retrieved. We all hear about people who can remember their youth, their phone number, or street address from 70 years ago, but they cannot recall what they had for breakfast. The memory of this morning's breakfast wasn't rehearsed, and wasn't very important, so it fades away quickly.

The most fundamental principle of the organized mind, the one most critical to keeping us from forgetting or losing things, is to shift the burden of organizing from our brains to the external world.

You'd think people would realize they're bad at multitasking and would quit. But a cognitive illusion sets in, fueled in part by a dopamine-adrenaline feedback loop, in which multitaskers think they are doing great.

Librarians are more important than ever before ... are uniquely qualified to help all of us separate the digital wheat from the chaff, to help us understand the reliability of the data we encounter.
