Introduction

When individuals dismiss information they’ve requested unconечно, often on irrational bases, it can be indicative of various logical fallacies. This practice undermines the importance of empirical evidence and critical thinking, fostering an environment where misinformation can thrive. This article explores the common fallacies that can arise in such situations, using specific examples to illustrate each point.

Confirmation Bias

Confirmation bias is a cognitive bias that occurs when people favor information that supports their pre-existing beliefs or hypotheses, and discredit evidence that contradicts them. This phenomenon is particularly evident when someone rejects a high-quality piece of evidence, such as a study by a PhD in a relevant field, by pointing to a less credible source, like a random individual on YouTube.

Examples and Explanations

In the case you've described, a person might dismiss the input of a PhD expert because they prefer information that aligns with their own preconceived notions. Such a bias can lead to the rejection of well-substantiated findings in favor of unverified claims. This type of cognitive bias is a serious obstacle to intellectual honesty and objective inquiry.

Adu Hominem Fallacy

The ad hominem fallacy occurs when a person attacks the person making an argument, rather than addressing the argument itself. In the scenario you mentioned, an individual might dismiss a PhD’s evidence by attacking the source, saying the expert is simply a random person on YouTube. This approach is fallacious because it diverts attention from the substance of the argument to the personal characteristics of the speaker.

Exemplified Case

Consider the example of a Christian rejecting an atheist’s argument by declaring it ridiculous without providing evidence. This is a form of ad hominem, where the ridicule is directed at the atheist rather than a response to the actual claim. The argument is thus dismissed on the basis of the speaker's perceived unreasonableness, rather than the logical and evidentiary aspects of the claim.

Appeal to Authority

The appeal to authority fallacy (also known as argumentum ad verecundiam) occurs when someone accepts a claim as true solely because an authority figure or expert, with no evidence, asserts it to be true. This fallacy can also manifest when someone dismisses well-substantiated evidence from a respected authority in a field without proper scrutiny.

Technical Example

Imagine a doctor on YouTube stating that follow-up evidence about the effectiveness and safety of a widely tested vaccine should not be considered because they personally dislike the idea of vaccinations. This statement cherry-picks a subjective opinion and dismisses robust scientific evidence based on personal bias, not on the merits of the evidence itself.

Handwaving Fallacy

A handwaving fallacy is a type of invalid argument where someone dismisses a point or argument without providing a concrete reason. This fallacy is often seen when a person claims that an idea is flawed without offering any substantive evidence or argument to support the dismissal. Simply stating that an argument is invalid is not enough; one must provide logical reasons and evidence.

Practical Application

For instance, if a genealogist dismisses a historical claim without providing evidence of why it is incorrect, they are committing a handwaving fallacy. It is also applicable when someone dismisses evidence by a PhD without presenting a valid reason to do so.

Conclusion

The rejection of important and relevant evidence by a PhD in a relevant field simply because it contradicts a preconceived notion can be highly problematic. Understanding and recognizing these logical fallacies can help individuals engage in more constructive and evidence-based discourse. By critically examining all evidence, regardless of the source, we can foster a culture of intellectual honesty and objective inquiry.
