"Studies suggest that an average coffee drinker’s consumption of coffee increases with age, from age 10 through age 60. Even after age 60, coffee consumption remains high. The average cola drinker’s consumption of cola, however, declines with increasing age. Both of these trends have remained stable for the past 40 years. Given that the number of older adults will significantly increase as the population ages over the next 20 years, it follows that the demand for coffee will increase and the demand for cola will decrease during this period. We should, therefore, consider transferring our investments from Cola Loca to Early Bird Coffee.”
My response:-
The author of the argument claims that with increasing age the average consumption of a coffee drinker increases whereas the average consumption of a cola drinker decreases, hence, according to the author, one should consider shifting their investments from the Cola manufacturing company to the Coffee manufacturing company.To support his claims the author provides the Studies conducted in the past 40 years that suggest the aforementioned trends. Though the underlying issue certainly has merit, due to lack of evidence, weak assumptions, and vague language the author's argument is unsubstantiated and deeply flawed. Some of the flaws in the argument are as follows.
To begin with,the author assumes that a 40-year-old trend will be relevant and applicable in the coming 20 years. Multiple factors come into play when it comes to demand and consumption of any product. Due to globalization and market integration consumers have new and multiple options ,the consumers of the future will not necessarily dwell on the products they had been using earlier. For example- the people had been using typewriters before the introduction of computers,and with the onset of computers the consumers switched to typewriters and the demand for the typewriters eventually died down.Since the market is so dynamic,the consumption patterns can change and the people can even switch to new products such as bubble tea,green tea or energy drinks thereby not following their drinking habits .
Additionally, the author relies on the usage of words such as increase' or decrease' to justify the change in consumption without providing any definitive numerical values.For example, a reduction in a cola drinker's consumption from 50 bottles a month to 5 bottles can be considered a monumental change however if a drinker reduces her consumption from 10 bottles a month to 9 bottles a month the decrease cannot be considered as a colossal factor while concluding.
Also, The author fails to identify the fact that with increase in population ,new cola or coffee drinkers will be added to the cohort.The previous studies cannot be representative of the upcoming generation and increase in the the new drinkers .
Although as written the argument is categorically unconvincing the author could have strengthened his argument by considering the addition of new drinkers for both the products, change in consumption pattern of the consumers and also making it relevant by assigning numerical values to words such as 'increase' or 'decrease'.If he had provided the following information the reasoning would have been significantly improved.
In conclusion the author present an implausible and deeply flawed argument.
