How ideas spread from person to person

A recent article in the New Yorker discusses, with examples, how ideas spread. The article, written by a medical doctor, describes how some healthcare ideas, like the use of anesthesia, spread very rapidly -- and that was in the nineteenth century. It also describes how some ideas, like being as sterile as possible when you are going to do surgery, spread much more slowly, and indicates some of the reasons why this might be so. Then it discusses some healthcare ideas which should be spread to third world societies, for their own sakes, and how difficult that can be.

The bottom line? For at least some medical changes, technological aids don't do much good towards getting people to change. It takes one-on-one demonstration, showing how to do something, and explaining why it's important..

The article is fascinating, but I can't help but be reminded of how the gospel should be spread. Using technology is OK, but what's really needed is one-on-one demonstration, showing how, and why it's important.

Thanks for reading! Read the New Yorker article.
