This project analyzes the logical fallacies surrounding the theory of SARS infection during its outbreak in Hong Kong. It articulates how a theory, structured as an if-then statement, can lead to flawed conclusions when individuals misinterpret the presence or absence of illness. The fallacies of denying the antecedent and affirming the consequent are explored, highlighting misconceptions in reasoning about health and hospital care. By dissecting these errors, the project emphasizes the importance of logical clarity in understanding medical situations.

ECONOMICS PROJECT--- Fallacy of an theory
What is a theory? • A theory is a set of definitions postulates, test conditions and predictions logically organized to explain phenomena. • It is an if- then statement. It explains and predicts that if the postulates and test conditions apply, then the predictions must happen.
Situation • It was the time when the SARS was spreading in Hong Kong… • The theory is:If one is infected by SARS, one will stay in the hospital.--- If A, then B In the statement, A is called the antecedent, while B is called the consequent.
Oh…if you have SARS, you should stay in the hospital or others may be infected also.
SO… There is a thinking…
Don’t come near me. You have infected by SARS…You should stay in the hospital… SARS patient!!!! If A (antecedent), then B(consequent).
HOWEVER… Somebody have the following thinking…
Oh…you are not infected by the SARS, you need not staying in the hospital. patient catching a serious cold Not A(antecedent), not B(consequent).
The monkey has committed the fallacy of denying the antecedent. Although I don’t have SARS, I should stay in the hospital since I have caught a serious cold. Therefore, the thinking of Not A, not B…is… WRONG!!!!
AND… Some people may think that…
IN THE HOSPITAL… If B(consequent), then A(antecedent). Oh!!!!…you are staying in the hospital, you are infected by SARS. You are in the hospital ALSO!!!! 100m
I am innocent… Staying in hospital does not mean that I have infected by SARS… I have just given birth to babies… The monkey has committed the fallacy of affirming the consequent. Therefore, the thinking of If B, then A…is… WRONG!!!!
Conclusion • Fallacy is an invalid reason that… • Not A, Not B.If B, Then A. WRONG!!!! WRONG!!!! With the statement given is: If A, Then B.
