Marianna: The problem of drunk driving has been somewhat ameliorated by public education and stricter laws. Additional measures are nevertheless needed. People still drive after drinking, and when they do, the probability is greatly increased that they will cause an accident involving death or serious injury.
*CONCLUSION: Additional measure are needed.
*Why?: Because
the probability is increased.
David: I think you exaggerate the dangers of driving while drunk. Actually, a driver who is in an automobile accident is slightly less likely to be seriously injured if drunk than if sober.
*CONCLUSION: You (Mariana) exaggerate the dangers of driving while drunk.
*Why?: Because the drunk driver is less likely (
probability) to be seriously injured (
severity).
-----------------
* COMMENT: Here we can clearly see that Mariana discussed the problem with regard to probability, and David discussed the same problem with slightly different aspect - probability of severity, which is not in line with Mariana's argument. -----------------
*POE:
(A) He contradicts himself.
-> NO, he did not.(B) He assumes what he is seeking to establish.
-> He did not make any additional assumption, he just repeated Mariana's argument(C) He contradicts Marianna’s conclusion without giving any evidence for his point of view. ->
He did not contradict Mariana's argument, he just stated that the argument is distorted.(D) He argues against a point that is not one that Marianna was making.
-> YES, Mariana looks at the probability while David approaches the argument with probability of severity. (E) He directs his criticism against the person making the argument rather than directing it against the argument itself. ->
NO, He did not criticized Mariana
