Detecting Denial Techniques: Quiz 8


The following are techniques used to deny science. Some techniques are sub-classes of others (e.g., ad hominem is a logical fallacy, false choice is an oversimplification).



  • Fake Experts: Presenting an unqualified person or institution as a source of credible information.
    • Bulk Fake Experts: Citing large numbers of seeming experts to argue that there is no scientific consensus on a topic.
    • Fake Debate: Presenting science and pseudoscience in an adversarial format to give the false impression of an ongoing scientific debate.
  • Logical Fallacies: Arguments where the conclusion doesn’t logically follow from the premises. Also known as a non sequitur.
    • Ad Hominem: Attacking the person/group instead of addressing their argument.
    • Ambiguity: Using ambiguous language in order to lead to a misleading conclusion.
    • False Analogy: Assuming that because two things are alike in some ways, they are alike in some other respect.
    • Misrepresentation:  Misrepresenting a situation or an opponent's position in such a way as to distort understanding.
      • Straw Man: Misrepresenting or exaggerating an opponent’s position to make it easier to attack.
    • Oversimplification: Simplifying a situation in such a way as to distort understanding, leading to erroneous conclusions.
      • False Choice: Presenting two options as the only possibilities, when other possibilities exist.
      • Single Cause: Assuming a single cause or reason when there might be multiple causes or reasons.
    • Red Herring: Diverting attention to an irrelevant point to distract from the original argument.
    • Slippery Slope: Suggesting that taking a minor action will eventually lead to major consequences.
  • Impossible Expectations: Demanding unrealistic standards of certainty before acting on the science.
    • Moving the Goalposts: Demanding higher levels of evidence after receiving requested levels of evidence.
  • Cherry Picking: Carefully selecting data that appear to confirm one position while ignoring other data that contradicts that position.
    • Anecdote: Using personal experience or isolated examples instead of sound arguments or compelling evidence.
    • Slothful Induction: Ignoring relevant evidence when coming to a conclusion. Similar to cherry picking but with an emphasis on neglecting inconvenient information rather than highlighting convenient information.
  • Conspiracy Theory: Proposing a secret plan to implement a nefarious scheme such as hiding a truth or perpetuating misinformation.
  • None of the Above: Statement is logically valid and doesn't contain any of the denial techniques listed above.


Identify the denial technique that best matches the arguments below (note that some arguments may not contain a denial technique). You will receive your score after you complete the quiz.

I feel a little bloated today, I’m never going to lose weight!
The word theism refers to a medical condition from drinking too much tea, and the church encourages theism, so the church should give out free tea.
Shadows in the Apollo moon landing photos are not parallel, proving that the scenes were lit from multiple angles in a studio.
We are very strong on our Second Amendment. ... You know they call it the slippery slope, and all of a sudden everything gets taken away.
Scientists weren't afraid to look into the strange physics behind lasers and semiconductors, so I don't think we should be afraid to look into telepathic remote-viewing.
Which argument is logically valid?
People are right to be concerned about climate change. But they are also right to be concerned about costly attempts to address it. Instead of restricting options for our next generation by borrowing against their future, we should choose solutions that adapt to climate change, buy time, and maximize the choices available to them in the decades and centuries to come.

What is an appropriate conclusion from this paragraph?
The 17th-Century Italian astronomer Francesco Sizzi wrote "There are seven windows given to animals in the domicile of the head: two nostrils, two eyes, two ears, and a mouth...From this and many other similarities in Nature, too tedious to enumerate, we gather that the number of planets must necessarily be seven."

What is an appropriate conclusion from this paragraph?
A new scientific report on climate change has concluded that we need to reduce CO2 emissions by 45% within 12 years in order to avoid dangerous climate change. In response, Senator Smith said “The world is not going to end in 12 years as some climate alarmists claim.”

What is an appropriate conclusion from this paragraph?
The theory of evolution holds that the process of natural selection and random mutation can account for the complexity of life. But the theory of evolution is just that: a theory. In other words, a conjecture, a hunch, or just an idea in someone’s head. There’s no direct, observable evidence for evolution.

What is an appropriate conclusion from this paragraph?
In the following examples, choose the argument that best matches the denialist technique: 
Single cause
Ad Hominem
Impossible Expectations
