Whether to Lean or Enrich

need to move into the
21st century where there exists hard data from scientific testing.

Can you refute THIS hard data:

February Program: Sentry Cylinders

anecdotal data snipped

jls: what you cited is NOT hard data, but someone's personal
experience. It may be valid, but it absolutely does not come from
controlled experiments following scientific principles.

But don't feel bad. Most engineers, and even many scientists, don't
really understand what science is nor the scientific method.

It's no wonder the world is generally f***ed up. Especially the
mid-east. The further a society is from following scientific
priniples in the culture, the more screwed up it is. American society
is usually one of the better societies about this though the current
president is reversing course.
