A comparative guide to science denial

When you watch science denial in action, you will see the same sort of arguments being used over and over, often in much the same order. Here is a handy-dandy cut-out-and-keep guide, with examples from:
 * 1) tobacco industry,
 * 2) creationists, and
 * 3) climate change deniers.

Denial of well-established evidence
The following are quotes from denialists about the purported lack of scientific evidence.

Listing legitimate research questions to cast doubt on a scientific theory
Denialists will point out legitimate research questions to generate doubt in the overall theory.

Denialist movements as public relations projects
The following are quotes analyzing each group from the perspective of public relations, quoting the denialists themselves.

Petitions of supporters, perhaps scientists
The following are statements from the petitions of denialist movements. Petitions are a common way of making a denialist movement more popular, and function as a argumentum ad populum to their validity.

Mere statistical data
Denialists often minimize the relevance of statistical data, as the following quotes indicate.

Purported conspiracy against denialist research or "rights"
Denialists will claim there is a conspiracy in the science they deny.

Use of Fake Experts
Denialists will quote an "expert", who, in fact, may have no credentials in the field, often while tarnishing legitimate experts.

Impossible standards for research
Denialists will demand an unreasonable amount of evidence, when in fact the evidence at hand is more than sufficent.
 * One central question for the evaluation of skepticism is 'what evidence would be convincing?' One sign that open-minded doubt has turned intractable is the answer: 'I cannot say.'"

Cherry picking, data and quote mining
Denialists will typically select only studies or data that favor their point of view and ignore others. Or, they might select quotes that are deceptive when quoted out of context.
