The following appeared in a print advertisement for a dietary supplement:
“According to a recent study, professional bodybuilders who used Train & Gain, a new protein supplement, over the course of three months experienced an increase in measured strength of up to 20%. Since Train & Gain is now available without prescription at all major pharmacies, superior results are no longer limited to professional athletes. Try Train & Gain today and you too can boost your strength and achieve professional-level performance in just a few months.”
Discuss how well reasoned you find this argument. Point out flaws in the argument's logic and analyze the argument's underlying assumptions. In addition, evaluate how supporting evidence is used and what evidence might counter the argument's conclusion. You may also discuss what additional evidence could be used to strengthen the argument or what changes would make the argument more logically sound.
=====================================================================
The print advertisement claims that by consuming Train & Gain one can achieve professional-level performance in just a few months and can boost one's strength. However, the author of the advertisement presents a poorly reasoned argument which is based on several questionable assumptions and unsubstantiated premises.
First, the argument is based on the unjustified assumption that the 20% increase in the strength of professional bodybuilders, as cited in the study, was the result of the consumption of Train & Gain. In assuming Train & Gain to be the cause of the increase, the author overlooks to consider several other reasons that could have played a part, either wholly or partially, in such an increase. For instance, the increase could be the result of the normal training program that the professional bodybuilders follow in their everyday life. The author could have strengthened the argument had he or she clearly established that the strength-gain is attributed to Train & Gain. One way that the author could provide support for this claim is by providing data on how much increase in strength similar athletes are likely to experience with and without the consumption of Train & Gain.
Second, the advertisement makes far reaching claims, none of which follow logically from the evidence that the author provides. the author claims in the advertisement that anyone can boost his or strength by consuming the product. But the evidence that the author provided in support was a study that was limited in its scope to professional bodybuilders. The author could have corroborated the argument if he or she had cited any studies done on average consumers from all demographic groups which also showed that the product helped all the possible types of consumers increase their strength.
Finally, in advertising the product, the author uses vague language to describe the effects of Train & Gain. The author suggests that the product can help achieve "superior results", but does not make it clear what such a term represents.
In sum, the argument is flawed for the aforementioned reasons and is therefore unconvincing. If the advertisement has included the items discussed above, then the argument would have been more thorough and sound.
