6. A HARD FACT OF LIFE<br />

replacement. The effectiveness of face-to-face dealings is recognized<br />

among businesspersons today as much as it was among the emissaries<br />

of antiquity.<br />

Serious doubts are raised as to whether technological means will ever<br />

satisfy the social need for communicating through personal contact. It is<br />

difficult to compare quantitatively the amount of information exchanged<br />

through personal contacts to that exchanged through technological<br />

means. The information content of body language, for example, cannot<br />

easily be measured in units, like phone calls or pieces of mail. But the<br />

insistence with which executives and politicians cling to their costly<br />

missions suggests that such a substitution may after all be “unnatural”<br />

or, at best, a slow one, much slower than the telephone-for-letter substitution.<br />

Another reason for which an a priori reasonable substitution may not<br />

display the expected trajectory is that the variable is not properly defined.<br />

The example of detergent substituting for soap mentioned earlier<br />

would not have followed a straight line had Fisher and Pry taken all<br />

soap. They carefully considered laundry soap only, leaving cosmetic<br />

soap aside. Complications can also arise in substitutions that look “unnatural”<br />

in cases of a niche-within-a-niche, or a niche-beyond-a-niche.<br />

In both cases two different S-curves must be considered for the appropriate<br />

time periods. In the straight-line representation such cases show a<br />

broken line made out of two straight sections.<br />

When close scrutiny does not eliminate irregularities, it means that<br />

there is something unnatural after all. A substitution may show local<br />

deviations from a straight-line pattern, which can be due to exceptional<br />

temporary phenomena. But such anomalies are soon reabsorbed, and the<br />

process regains a more natural course. As an example of this, Fisher and<br />

Pry point out the replacement of natural by synthetic rubber during the<br />

war years. In the 1930s synthetic rubber was slowly making an appearance<br />

in the American market as an inferior alternative to natural rubber,<br />

which was imported in large quantities from foreign sources. During the<br />

early stages of World War II, imports of natural rubber were largely cut<br />

off and, at the same time demand for rubber increased considerably. A<br />

large national effort during these years resulted in improving the quality<br />

and reducing the production costs of synthetic rubber.<br />
