Are you sure?

Bad mathematics is mathematics that leads to an incorrect answer, but it's still mathematics.

Bad military strategy leads to defeat on the battlefield, but it's still military strategy.

Bad reasoning leads to incorrect conclusions, but it's still reasoning.

Badly done work leads to poor results, but it's still work.

Badly done science or science that is deliberate in creating horribly destructive things (like poison gas or atomic bombs) (and that's what I mean by "bad science") is still going through the outward motions and all the formalities and procedurs of science, but it leads to invalid theories, viciously destructive inventions, and/or misinterpreted results. It is still science, it's just not very useful science, that's all. It still requires labs, research papers, trained staff, reference materials, controlled conditions, and all the other acoutrements of science, so it's still science. Just piss poor science. ;-) And it happens all over the place at the behest of corporations (who desire a certain result) and governments (who desire a certain result). Their desire for that result is what creates the bad science.
