Logic Reasoning Flashcards
Resolution / Resolve the Paradox
Most Powerful answer choice to make the paradox make sense
False Dichotomy (False Dilemma)
Pretends there are only 2 options where there could be more
Ex: Mia went to the park and was on the swing set. She came home with a bruise so she must have fallen off the swing set
Flaw - False Start
Assumes both groups are the same in every way except the one called out as a part of the study
Ex: Comparing a group of exercises to non exercises assuming the ones who exercise are healthier
If the sufficient condition is absent
You ignore the conditional statement
Overgeneralization
Takes something small and applies it to all
Ex: Pellegrino taste like adventure water when chilled so all water taste like adventure water
Question Stem: The conclusion drawn above follows logically if which one of the following is assumed?
Sufficient Assumption
Question Type: Main Conclusion / Main Point
The conclusion
Question Type: Strength
Most powerful thing you can find to help the arguments conclusion
Question Type: Weaken
The most powerful thing you can find to destroy the arguments conclusion
“If” part of the conditional is called
the sufficient [condition]
“Then” part of the conclusion is called
the necessary [condition]
Conclusion Indications
Therefore Thus Accordingly Consequently It follows that So
Question Type: Counter
Most powerful answer choice the 1st speaker could say to destroy the second speakers argument
If the sufficient condition is present …
the conditional statement must follow
Premise Indications
Because For Since As Given That
Question Type: Sufficient Assumption
Most powerful answer choice that proves the conclusion 100% true
What does a necessary assumption do?
Has to be true, if the conclusion is true
Most Strongly Supported
The answer choice you can prove is very very very likely to be true
Bad Causal Reasoning
Concludes one thing causes the other
Bad Conditional Reasoning
Read conditional premise backwards w/o negating or negates premise and reads forward
Ex: If i get on a plane I’m going to Spain. Everyone in Spain speaks Spanish. So if I get on a plane I speak Spanish
(plane -> Spain - > Spanish)
Question Stem: Which one of the following can be properly inferred from the statement above
Inference / MBT
What do premises do?
Support the conclusion
What do conclusion do?
Rely on premise for support
If the sufficient is present
Must have necessary condition
If the necessary is absent
Can’t have sufficient
Sufficient Indicators
If When(ever) Any(time) All Every(time) In order to People who Each
Necessary Indicators
Then Must Necessary Required Only (if) Depends Need (to) Have to Essential
Conditional : If and Only If
Each term is both the condition and necessary condition
Conditional: Unless
~ The way things always are -> Exception
