Which method of reasoning is being used if a speech concludes that numerous attorneys convicted recently of fraud suggests that unethical lawyers are common in the U.S.?

The method of reasoning utilized in this speech is reasoning from specific instances. This approach draws a general conclusion based on a limited set of specific examples or cases. In this instance, the speaker points to several attorneys who have recently been convicted of fraud as evidence to support the broader claim that unethical lawyers are prevalent in the United States. By highlighting these specific cases, the speaker attempts to create a wider assumption about the ethical standards within the legal profession.

This method is often employed when speakers illustrate a point by referencing particular occurrences that suggest a larger pattern or trend. While this reasoning can be persuasive, it may also be criticized if the specific instances are not representative of the broader population.
