We are human because we can fantasize.

If you wanted to create an education environment that was directly opposed to what the brain was good at doing, you would probably design something like a classroom.

Here's why this matters: Studies show that a person who is interrupted takes 50 percent longer to accomplish a task. Not only that, he or she makes up to 50 percent more errors.

A third or more of the brain is devoted to visual processing, not true of any other sense. We have color vision and it is truly binocular. This sophistication is not true of other senses, such as smell, where many genes are actually mutated and no longer work.

Human learning is a very aggressive style in its native state. I am not sure why, though it is a very useful trait in an unstable, unpredictable living environment.

To put it bluntly, research shows that we can’t multitask. We are biologically incapable of processing attention-rich inputs simultaneously.

What's obvious to you is obvious to you.
