Entry 4_Đoàn Thị Thu Huyền


Entry 4
Argument structures and fallacies
Item 1:
Henry went to the football game, and then he had a car accident. Therefore, the football game caused his car accident.

=> post-hoc fallacy

Henry went to the football game and he had a car accident
The action that Henry went to the football preceded his car accident
The preceding action is the cause of the following one
----------------------------------------------------------------
The football game caused his car accident

(False premises)

The event “Henry went to the football game” precedes “he had a car accident”. The conclusion that the football games caused his car accident is false. The two events may have happened in that order but the first action was not responsible for the second.
Item 2:


What fits your busy schedule better, exercising one hour a day or being dead 24 hours a day?
ð     Fallacy of False Dilemma
Either he exercises one hour a day or he is dead 24 hours a day
He does not exercise one hour a day
--------------------------------------------------------
He is dead 24 hours a day

In the picture, it is doctor’s advice to patient. The doctor tells that either he exercises one hour a day or he is dead 24 hours a day. It means he only chooses one of tow choices. However, there are some other options to patients and the doctor does not mention here. For example, he does not take exercise everyday but he takes a special diet to keep healthy.
Item 3:
I asked six of my friends what they thought of the new spending restraints and they agreed it is a good idea. The new restraints are therefore generally popular.

ð     Fallacy of hasty generalization

Six of his friends thought the new spending restraints is a good idea
Most other people like six of his friends
People often do or carry out the good ideas
---------------------------------------------------------
The new restraints are therefore generally popular

False premises
Six of his friends are a small number and it can not represent the whole community. Therefore, the new restraints can not become popular if he only rely on thoughts of six of his friends.
