EDIT: Political science is probably the most truthful science that exists. This is because it formally admits that it uses lies in controlling those that it is used to control. Other science has lies only by accident, doesn't admit to wanting lies, and is often used by political science to skew the facts.
and the least truth full is Keynesian the(r)orists... even the "devil" can't find their souls...
^^ This!
The thing is science doesn't take sides. it can be manipulated and the reports falsified but true science doesn't lie.
There certainly is, though, a "science of propaganda."
