Epistemology in the Gym – Learn How to Make Your Own Decisions


The internet is flooded with diverse information about food, supplements, training programs, and movement patterns. Some of this information is accurate and beneficial to your training, while some is misleading or downright false. Navigating this sea of advice can be overwhelming. So, how do you figure out what is true and what’s worth incorporating into your fitness routine? The answer lies in epistemology – the study of knowledge and how we come to understand truth. 🌐

What Is Epistemology? 🤔

Epistemology is a branch of philosophy that explores the nature, sources, and limits of knowledge. It’s all about understanding how we know what we know and how we can justify our beliefs. In the context of fitness, epistemology helps us discern which claims about training, diet, and supplements are worth believing. By learning to analyze information and recognize different types of justifications, you can make more informed decisions about your fitness journey.

What Is a Justification in Informal Logic? 💭

A justification is the reasoning behind a belief or claim. In informal logic, justifications help us determine if a statement is likely true. When you decide to believe that a certain supplement or exercise will benefit your training, you’re using some form of justification. However, not all justifications are created equal, and understanding their types can be a powerful tool in the gym.

Types of Justifications in the Gym 🏋️‍♀️

Let’s explore four common types of justifications used in fitness: scientific, anecdotal, authoritative, and mechanistic. We’ll analyze each of these in the context of a popular claim: “People interested in gaining more muscle should take creatine.”

1. Scientific Justifications 📊🔬

A scientific justification is derived from the understanding of scientific data and research. It’s one of the most reliable ways to determine the truth of a claim, but it requires effort and a willingness to delve into sometimes dry, complex studies. For example, you might read every meta-analysis and randomized controlled trial (RCT) related to creatine supplementation to understand its effects on muscle growth.

Science is a fantastic tool, but interpreting studies correctly is no easy feat. It involves understanding study design, statistical analysis, and the broader body of literature on a topic. If you’re willing to put in the work to understand the science, you can comfortably rely on scientific justifications for your claims. In the case of creatine, numerous studies show it increases strength and muscle mass, providing a solid scientific basis for the claim.

2. Anecdotal Justifications 🗣️

Anecdotal justifications come from personal experience or observations. For instance, if you started taking creatine six months into your training and noticed a sudden increase in your lifting capacity, that would be an anecdotal justification for the belief that creatine helps build muscle.

While anecdotes are less reliable than scientific evidence due to their subjective nature and limited scope, they still hold value. After all, fitness is a personal journey, and what works for others might not work for you. Your personal experiences can guide you in making decisions, especially when scientific data is inconclusive or lacking.

3. Authoritative Justifications 📢

An authoritative justification involves relying on the advice of an expert or a trusted figure. For example, you might take creatine because a respected trainer on YouTube or a well-known fitness coach recommends it. While appeal to authority is technically a logical fallacy, it’s still a practical method for gathering knowledge, especially when you trust the expertise of the individual.

However, authoritative justifications come with risks. Not all experts are infallible, and sometimes, even well-intentioned professionals can be wrong. It’s important to critically evaluate the credibility of the authority and cross-check their recommendations against scientific evidence when possible. But let’s be real – none of us can read every study out there, so sometimes we do have to lean on those we trust.

4. Mechanistic Justifications 🧬

Mechanistic justifications are based on the biological or chemical processes that underlie a claim. For example, you might reason that since ATP (adenosine triphosphate) is what powers your muscles, and phosphocreatine helps generate more ATP, taking creatine could enhance your ability to do more reps and ultimately build more muscle. This makes logical sense, but it comes with significant caveats.

The human body is a complex, dynamic system that we do not fully understand. Even if a mechanism appears to make sense, it doesn’t guarantee that the intervention will work as expected. Many fitness myths arise from oversimplified mechanistic reasoning. While mechanistic justifications can offer valuable insights, they are inherently flawed and risky as standalone justifications.

How to Use These Justifications in Tandem 🧩

Imagine a scenario where a gym buddy says, “Hey, you should take this awesome pre-workout; it will make you stronger!” You’re skeptical, as you should be. Relying solely on his word (an authoritative justification) might be a mistake since you don’t know or trust him.

Instead, you decide to look at the scientific literature, which shows that the supplement doesn’t work. Now, the scientific justification seems to reject the claim. Next, you consider the ingredients and their mechanisms, but you realize that your knowledge of biology isn’t deep enough to form a solid mechanistic justification.

Despite the initial negative signals from authoritative and scientific justifications, you decide to try the supplement yourself. Surprisingly, you notice a significant improvement in your performance. In this case, the anecdotal justification provided the final piece of evidence for you to make an informed decision.

A Warning: The Fallacy Fallacy ⚠️

Before wrapping up, it’s crucial to mention the fallacy fallacy. This logical misstep occurs when we dismiss a claim outright simply because it was argued poorly or based on faulty reasoning. For example, imagine a gym bro telling you that a certain pre-workout works because it contains bull semen, and since bulls are strong, drinking it will make you strong too. Clearly, this is a terrible justification and a prime example of flawed mechanistic reasoning. However, just because the justification is nonsense doesn’t automatically mean the pre-workout itself won’t be effective for you. The supplement might still contain other ingredients that could actually benefit your training. Beware of hastily disregarding a claim just because its initial justification is weak. Dig a little deeper before you make up your mind. 🔍

Your Own Epistemic Toolbox 🧰

Navigating fitness information requires a balanced use of different justifications. While scientific justifications are often the most reliable, they aren’t always feasible for everyday decisions. Anecdotal, authoritative, and mechanistic justifications also have their place but should be approached with caution. Your best strategy is to use these justifications in tandem, cross-referencing where possible, and being open to adjusting your beliefs based on new information. 💡

In the gym, making your own decisions is less about finding a one-size-fits-all truth and more about understanding which epistemic tools work best for you. Use them wisely, and you’ll find yourself better equipped to sift through the noise and make choices that align with your goals. 🏆
