False accusation of junk science

Interestingly, in recent years charges of bad science and junk science in public policy debates has led to bogus accusations of bad science becoming a propaganda technique in its own.

In this case, the propaganda technique may merely be an attempt to tack "bad science" as a negative buzzword onto whatever is being attacked. It may be effective because counter-arguments against these claims are long, complex and difficult to understand.

These accusations are typically levied by think tanks and public relations firms under order from tobacco companies and businesses that have something to gain by denial of global warming.
