1) Surely you don't mean to compromise the objectivity of science? How could we possibly hope to produce objective accounts of the world if we allow stakeholders to have a say in simulations?

ANSWER:

The fear is not unfounded; eg consider the failure of "Maoist Mathematics:"

"Before the cultural revolution some of us believed in the beauty of mathematics but failed to solve practical problems; now we deal with water and gas pipes, cables, and rolling mills. We do it for the country and the workers appreciate it."

(Dialog from 1976 US mathematics delegation to the People's Republic of China)

How can we have both scientific independance AND the collaboration of stakeholders?
a. Seek collaboration rather than control
b. Seek consensus rather than censure
c. Seek diversity rather than unity
d. Seek falsification, not verification
