Appeal to Nature Fallacy | Definition & Examples

The appeal to nature fallacy occurs when an argument assumes that whatever is deemed natural is inherently superior to whatever is considered unnatural. The claim that an idea or practice is natural is used as a replacement for a logical, evidence-based argument.

Arguments that commit this fallacy typically claim that something is safe, healthy, practical, or morally good solely because it is natural.

Appeal to nature fallacy example in health
“Herbal supplements are derived from plants, so they’re safer than prescription drugs.”

This claim exemplifies the appeal to nature fallacy because it relies entirely on the fact that herbal supplements are “natural” to argue their safety. The argument fails to consider the importance of scientific evidence. In reality, some herbal supplements can have detrimental effects, and in many countries they aren’t required to be tested for safety like pharmaceuticals are.

The appeal to nature fallacy can be found in debates about food, lifestyle, health, and environmental policy among other subjects.

What is the appeal to nature fallacy?

The appeal to nature fallacy occurs when something is assumed to be good simply because it is natural or bad solely because it is unnatural.

Appeals to nature oversimplify complex issues by equating what is “natural” with positive qualities, while disregarding the potential benefits of alternatives.

The appeal to nature fallacy is an informal logical fallacy, which means that it involves weak reasoning rather than a structural flaw. It is an unsound form of argumentation because it overlooks complexities.

The appeal to nature fallacy is also a fallacy of relevance, a category of errors that occur when the premises of an argument are considered irrelevant or barely relevant to the conclusion.

The appeal to nature fallacy is often effective at persuading an audience because it appeals to certain cognitive biases, or innate tendencies toward flawed patterns of reasoning:

  • Naturalness bias: Preference for natural or familiar things over artificial or unfamiliar ones
  • Ambiguity effect: Avoidance of options that are unclear or ambiguous in favor of those with a known outcome

Appeal to nature fallacy examples

Examples of the appeal to nature fallacy can be found in many domains, including health and medicine, environmental and public policy, diet and nutrition, beauty and personal care, agriculture and farming, technology and innovation, child rearing, and lifestyle choices.

Appeal to nature fallacy example in politics
A politician argues, “As your elected representative, I must emphasize the dangers of vaccination. They contain synthetic substances, which interfere with the natural balance of our immune systems. Our ancestors relied on a natural lifestyle to stay healthy, not vaccines.”

The vaccination claim is an appeal to nature fallacy because it assumes vaccines are harmful purely because they are “unnatural,” ignoring their proven benefits in disease prevention.

In media and advertising contexts, the appeal to nature fallacy can take the form of biased reporting and advertising, which may portray natural products as inherently superior without evidence.

Commentators may advocate for “natural” practices as inherently superior without acknowledging evidence to the contrary. This can reinforce biases and misinform audiences about the complexities of health, environmental, or societal issues.

Appeal to nature fallacy example in media
A podcaster argues, “The problem with today’s children is social media. Children should play outside instead of looking at a screen. It’s the way humans have always experienced childhood, surrounded by nature.”

This claim exemplifies the appeal to nature fallacy because it assumes that social media is without any benefit solely because it is not considered “natural.”

Why is the appeal to nature fallacy a problem?

The appeal to nature fallacy is illogical because it oversimplifies complex issues. There are several problems with equating naturalness with inherent superiority or goodness:

  • Reductive: It oversimplifies complex issues.
  • Unscientific: It involves disregarding evidence and critical thinking.
  • Detrimental to decision-making: It can lead to harmful or suboptimal decisions and actions.

How can you avoid the appeal to nature fallacy?

To avoid the appeal to nature fallacy, it’s important to critically evaluate claims and understand that “natural” isn’t always good and what’s “unnatural” isn’t always bad.

  • Acknowledge complexity: Recognize that something can be natural or unnatural and still have benefits and drawbacks.
  • Seek scientific evidence: Look for empirical research and data to support claims about safety, efficacy, and benefits.
  • Avoid simplistic dichotomies: Understand that categorizing something as purely natural or unnatural often oversimplifies complex issues.

When is an appeal to nature a fallacy?

A non-fallacious argument can include the idea of what is “natural” or “unnatural” along with specific, evidence-based reasons.
