In teaching, it is a common practice to repeat a peace of information several time, hoping that it will eventually reach the majority of the class. Likewise, in marketing, potential consumers are continuously bombarded with repeating advertising messages. There are many examples of this kind of repeatability, and while it obviously works, it is also clear that this approach is wasteful in terms of the information bandwidth that each of us is capable of receiving or transmitting during s typical day (or a lifetime.)
The balance between delivering the message and annoying the audience by unnecessary repeating it is very relevant for photographers. For example, when I want to share my travel photos with friends, I send them a link my Flickr photo stream before I leave for a trip, so that they can follow along, if they like. It turns out that most friends (those who genuinely want to see the photos) visit the link once and expect it to be re-sent periodically as a reminder. Wouldn’t it be nice if each of us was able to cut through the chatter and not need to be repeated things twice? Perhaps, our minds are not wired to capture things right away. But there are certainly exceptions, or rather, exceptional people out there.
Richard Feynman, in his autobiographical “Surely You’re Joking, Mr. Feynman!” describes an episode when prominent physicists were debating a technical problem, which was a part the Manhattan project. Despite tremendous time pressure, no one felt the need to repeat his statement in order to promote his point of view – there was an implicit trust that the other would hear what was stated just once. As Feynman said, “These were very great men indeed.”
