Hypothesis

by ssgmatter » Mon Mar 15, 2010 7:00 am
Modern science is built on the process of posing hypotheses and testing them against observations-in essence, attempting to show that the hypotheses are incorrect. Nothing brings more recognition than overthrowing conventional wisdom. It is accordingly unsurprising that some scientists are skeptical of the widely accepted predictions of global warming. What is instead remarkable is that with hundreds of researchers striving to make breakthroughs in climatology, very few find evidence that global warming is unlikely.

The information above provides the most support for which one of the following statements?

(A) Most scientists who are reluctant to accept the global warming hypothesis are not acting in accordance with the accepted standards of scientific debate.
(B) Most researchers in climatology have substantial motive to find evidence that would discredit the global warming hypothesis.
(C) There is evidence that conclusively shows that the global warming hypothesis is true.
(D) Scientists who are skeptical about global warming have not offered any alternative hypotheses to explain climatological data.
(E) Research in global warming is primarily driven by a desire for recognition in the scientific community

here i m stuck between B and C

my logic:

Global warming hypothesis-->scientists believe that the preidiction of the global warming are wrong....however the scientists have proved global warming predictions are not wrong....so that shows that global warming hypothesis is actually wrong rather than true accroding to choice C

So it should be B...

Please confrim the logic used to deduce this one

a-->scientific debate....out of scope
d-->climatological data...arg does not discuss this
e-->desire to get more recognition..out of scope arg does not discuss this

So it is B

Please correct me if i m wrong
Regards,
Phil

my concern however with B is it says motive...now where is this motive mentioned in the argument....m really confused here...please explain

The information above provides the most support for which one of the following statements?

(A) Most scientists who are reluctant to accept the global warming hypothesis are not acting in accordance with the accepted standards of scientific debate. - Incorrect - This option is extreme
(B) Most researchers in climatology have substantial motive to find evidence that would discredit the global warming hypothesis. - Incorrect - This option is extreme
(C) There is evidence that conclusively shows that the global warming hypothesis is true. - Incorrect - If there is a evidence and it conclusively shows that the global warming hypothesis is true, then it is not possible to have few scientiest, who find evidence that global warming is unlikely
(D) Scientists who are skeptical about global warming have not offered any alternative hypotheses to explain climatological data. - Incorrect - there is a possibility that scientiest might have provided some evidence. However, it is not mentioned in the passage
(E) Research in global warming is primarily driven by a desire for recognition in the scientific community - Correct - 'Nothing brings more recognition than overthrowing conventional wisdom' means there is a desire for for recognition in the scientific community. IMO this is correct

From the stem ....." striving to make breakthroughs".This corresponds to the term "motives " used in B.

I am skeptical about B.
Notice in the stimulus- some scientists are skeptical of the widely accepted predictions of global warming

Whereas in the answer choice: Most researchers in climatology have substantial motive to find evidence that would discredit the global warming hypothesis.

Notice the shift in probability indicators. You can talk about 'most' when a data for 'some' is given.

What is the source of this question?

(D) Scientists who are skeptical about global warming have not offered any alternative hypotheses to explain climatological data.
(E) Research in global warming is primarily driven by a desire for recognition in the scientific community
I got 'B' on my own, and here's how:

A - "standards of scientific debate" is out of scope (imo)
B - "most researchers" and "substantial motive" is much softer language, and sticks with the premises given.
C - "conclusively" is too strong of a word to use, when the question itself says "very few find evidence". Those very few make it a partial, not absolute, conclusion.
D - again, this says "scientists have [absolutely] not" offered any evidence, when in fact, few have. Too strong.
E - Opposite. Research in disproving the global warming hypothesis is what is driving the scientists.

Therefore, B must be the correct answer.

fibbonacci,

I think the shift is fine.

when the author is using some, he is talking about the whole scientific community. Some scientists......
Out of all the scientists, the ones who are researching about global warming are just "some of all"


Whereas, if you consider only Climatologists, all of them or most of them would be following the basic process of Modern Science : "To prove the hypothesis wrong" (motive).

Hypothesis in their case would be "to prove global warming unlikely".

So, IMO the shift is justified and B is the correct answer.
Regards,
Harsha

"Most" is justified by the usage of" hundreds of researchers "...

In my opinion the move from some to most is justified because is that most have the motive. When you read some it says "scientists are skeptical of the widely accepted predictions of global warming". Choice B doesn't mention skepticism rather it mentions motive which is substantiated by "Nothing brings more recognition than overthrowing conventional wisdom".

"hundreds of researchers striving to make breakthroughs in climatology, " doesn't help too much because these hundreds could be amongst tens of thousands, so not Most or could be 150 in 200.

Someone above mentioned that E is correct, I do not agree with E because E says

"Research in global warming is primarily driven by a desire for recognition in the scientific community" The argument does not mention desire for recognition is the main reason for research (In other words Primary reason why Scientist do research is to gain recognition)

What do you guys think.
