Comparing the work habits of two people who have the same last name is an example of a faulty analogy. Their name tells us nothing about their abilities and ethics.
You're absolutely right! Comparing the work habits of two people solely based on their last name is indeed an example of a faulty analogy. Last names do not provide any reliable information about an individual's abilities, work ethic, or any other relevant factors.
When analyzing and making comparisons between individuals, it's essential to consider factors that are actually relevant and comparable, such as their education, experience, skills, references, and personal qualities. By focusing on these aspects, one can make a fair and accurate assessment of their work habits or any other relevant attribute.
