Key tactics
- Here's an example of a flawed argument of this type:
- Gladis thinks the website we are on right now is called 7sage.com. She claims to know this because she cast her soul into the astral plane and communed with a goatman on Ganymede, who told her this website is called 7sage.com. Obviously Gladis is a crazy person, so this website must not be 7sage.com
- Just because the evidence offered FOR a claim does not hold up, that absence or weakness of evidence does NOT count as evidence AGAINST the claim.
Answer choice tips
- Example answer choices that point to this flaw:
- rejects the possibility that what has not been proven is nevertheless true.
- infers that there is no extraterrestrial intelligence in neighboring star systems from the lack of proof that there is.
- reasons that since Smith never disproved the claim that he threatened Lopez, he did in fact threaten her.
