THREE INSTRUMENTS

(worth repeating)

We construct three forms of instruments.

1- Physical Instrumentation (the instruments)

2- Logical Instrumentation (the logics and methods)

3- Social Instrumentation (institutional)

And of three, the third is most important, since it is the hardest to develop and control, because the incentives of individuals are contrary to the production of instrumental measurements.
