Question #11

I got this question correct. What is the name of the flaw? Is it 'Absence of Evidence'?

Hi Tebanks,

I think there is indeed an absence of evidence to support this conclusion. You can check out the "33 common lsat flaws" in the lesson on errors in reasoning

Thank you

I did not chose (e) because it states that the "The author provides no specific evidence", I thought in flaw questions the author does not necessarily have to provide specific evidence.

For flaw questions, the right answer must be something that the author did, and that is incorrect. While it is generally true that we do not always need specific evidence, the issue here is that the author relies on a bold conclusory statement without providing any proof for it.

That is, the argument flows as follows:
All species eventually go extinct, so anyone claiming that tech is accelerating extinction is wrong. Those species would have gone extinct anyways even without the tech.

The problem is that the author fails to actually engage with the idea that tech is accelerating the rate of extinction. E does articulate this flaw: that the author fails to provide evidence of the fact that the extinctions would have happened even without tech. While this could be phrased in a few different ways, the right answer must just describe what the author did wrong- and failing to provide evidence of something whose absence is a flaw is in itself a flaw.
