Market vs politicians: Who will determine the true value of resurgent shilling?

"Hard" scientists have that liberty; they can manipulate variables to see the effect on another variable. If you heat a piece of metal, it expands. If you add a dye to water, it diffuses, and if you mix magnesium and water, it will result in an explosion.

This direct observation, use of data and replicability give science its character. Humanities admire the methods of hard science to the extent of declaring themselves social sciences.
