We learn more about how human brains work. And that leads us to ideas about how to make human brains work better.

When someone is in a state of flow, that person's brain is not thinking about anything - it's just processing things through chunks at a total instinct level. Athletes in a state of flow describe knowing what will happen just before it does - knowing how a defender will react to a certain move an instant before doing it. Of course, if you know what will happen, you can succeed at doing it, so an athlete in flow has a stand-out game.

If you spot a market where the only choices are at either one end or the other - high fidelity or high convenience - there's probably a big opportunity at the other end. That was the opening for Federal Express, for instance. When it started, there was only one mail service in America - the US Postal Service, which was high convenience. Fred Smith created a high-fidelity mail service.

Some of what we're learning suggests a balance between exposing children to new things, yet giving them a chance to repeatedly experience something they enjoy, which builds "chunks" of information in their brains.

Who "wins" and who "loses" depends on when you measure it.

In the long run magazines can't be a convenience play - the Web has stolen that. So magazines have to be high fidelity - a fantastic experience - to thrive. Magazines will survive the Internet age, but only the ones that give people an experience they just can't get anywhere else. A magazine will have to be truly loved to make it.

If you want to stand out, find a way to be either high fidelity or high convenience in whatever you do. If you're halfway in between on both measures, you're not going to make people feel very excited about you.
