I thought the difference between religious and scientific teachings was that scientific teachings didn't have to worry about dilution?

More of a difference between things that are hard vs. easy to teach and measure. Businesses have the same problem with a great CEO trying to hire great employees, dilution of corporate culture, etc. - they have highly quantifiable output at the end of the day, but in the middle of the day and the middle steps of the process, it's not as easy to measure.

I anticipate a beginning period extending for at least several years when we don't have good metrics because we're still trying to develop them.
