Leni: Colm has made extensive claims that the consumption of red meat is a primary cause of colon cancer in the indigenous population of Juong. But Colm’s own data shows only a strong correlation between the consumption of red meat and the incidence of colon cancer in the country, and since any self-respecting scientist knows that correlation does not prove causation, Colm’s claims must be false.

Which of the following describes an error in Leni’s reasoning?

(A) To fail to establish causation is not to succeed in disproving causation.

(B) Colm’s data is not provided for the reader’s own analysis.

(C) Since Colm has demonstrated correlation, his arguments must be accepted.

(D) She fails to cite any other studies of the population of Juong.

(E) She attacks Colm’s credibility rather than the basis of his arguments.

Thanks
AK

While Leni is right that correlation does not prove causation, consider the logic of that statement. If I say that I failed to prove something, does that mean that I proved the opposite? Failure to demonstrate the existence of something isn’t proof that that thing doesn’t exist – absence of proof is not proof of absence – so (A) is the answer.

I can see 13 people have tried the question guys please give Kudos if you liked the question and help me unlock tests :-D

Thanks

Which of the following describes an error in Leni’s reasoning?

a) To fail to establish causation is not to succeed in disproving causation - Correct
b) Colm’s data is not provided for the reader’s own analysis - No where is mentioned about reader's analysis of passage.
c) Since Colm has demonstrated correlation, his arguments must be accepted - Leni ask for rejection of Colm's claim and not accepting it.
d) She fails to cite any other studies of the population of Juong - No study is given. Only Colm's claim about Juong is given.
e) She attacks Colm’s credibility rather than the basis of his arguments - She nowhere attacks Colm's credibility in passage.

Hi guys,

I understand why the answer (a) is right, but I have problems to eliminate the answer (e).

I have read the statement and reasoned the answer in the following form:

Colm has made extensive claims that there is a causal relation between red meat and color cancer.
Leni affirms that strong correlation is not causal relation and that any self-respecting scientist knows it.
Therefore, Colm’s claims must be false.

Then

Since any good scientist must known the different between correlation and causal relation and Colm does not know, Colm is not a good scientist. If Colm is not a good scientist , then Colm’s claims must be false.

How can I avoid this mistake? Where am I screwing up everything?

Correlation does not prove causation but not excludes it

Using POE it is clearly A. All other choices are either OoS or extreme.
