silly question with the over sharing example — is it possible to reframe it as a conditional logic statement?
wasn’t in school -> I peed my pants (conditional)
I didn’t pee my pants -> I was in school (contrapositive)
It’s not a Lawgic moment, because the sentence isn’t really arguing for anything or making a conclusive statement, but doesn’t the same structure apply?
I don't like how instead of breaking down the S/N conditions we are relying on indicators here. We just skipped over why each clause was S or a N condition.
Would have been nice to have touched on the contrapositive in the initial mention of the four steps of translating conditional indicators. Giving mention to it at the end of this lesson feels messy and somewhat threw off my groove #feedback
I was feeling some confusion earlier about sufficient and necessary conditions. My biggest takeaway that helped me get over this hump is that you need to get over how weird the necessary condition sounds and just accept the form of the argument.
Think about the previous Anderson v. King County argument. The necessary condition is showing that the defining characteristic of a class is an immutable trait. In order to achieve the sufficient condition (qualifying as a suspect class) then it is necessary to prove that immutable trait.
The zombies argument can be confusing because the necessary condition of the market crashing, seems like one that can happen because of other reasons. Necessity does not imply the condition at hand is limited to the sufficient claim. Think about the subset, superset forms of this argument. The market crashing is the superset. There are other ways for the market to crash that do not involve the subset of zombies. Maybe there is a smaller subset in the market crashing superset which is a weird virus goes around causing people to shrink into ant-size!
i found this helpful as a way of notating, in case someone else finds it helpful too:
strip away the modifiers and you'll get:
"zombies attack, market crash"
in notation it becomes ZA --> MC
basically, remove the modifers such that the conditional logic still makes sense in English.
Then assign notations to the logic in English

What benefit will taking the contrapositive give me
How would this concept look w/o the 'if' and 'then' present?
All people who go to Iv deli get BCCF, it is necessary for a healthy and happy life.
Step 1: All
2: people who go to Iv deli get BCCF… it is necessary for a healthy and happy life
Get BCCF > Happy life
If BCCF is not necessary for a healthy and happy life, then not all people who go to Iv deli get BCCF
"All cars require oil changes, new oil is necessary to function normally."
Step 1: All
Step 2: Cars requiring an oil change to function normally.
Step 3: C, O
Step 4: C -> O
Step 5: /o -> /c
If the car is functioning normally, new oil is not required.
The main concept in my example (if I'm not mistaken) is all cars require oil changes (1) new oil is necessary to function normally (2).
Step 1: when
Step 2: zombies attack NYC, real estate market crash
Step 3: z, m
Step 4: z -> m
Step 5: /m -> /z
when
zombies attack NYC, real estate market crash
z, r
z -> r
/r - > /z or if the real estate market does not crash, zombies will not have attacked nyc
i felt compelled to change the tense when flipping and negating for some reason

Wow i was thinking it has been a long time since a skill builder and it's the next section. I am the wizard
When zombies attack New York City, the real estate market will crash.
Z --> R
/R --> /Z
flip it around wicked witch
wait this is so cool!
just to make sure, sufficient condition always on the left and necessary condition is on the right?
I chose to remember these by using "A,E,I,O,U"
It isn't perfect because you have to think of "W" words instead or words that start with "U" but it was helpful.
A- Any, All
E- Every
I- If
O- The Only
U (W)- Where When
"The only" is the lone "only" indicator that falls in . group 1. Other "only" words are group 2.
if a toddlers mom leaves the room, they run after her.
IF
toddlers mom leaves the room, they run after her.
leaves -> run after
/run after --> /leaves
if the toddler did not run after their mom, she didn't leave the room.
I don't like how instead of breaking down the S/N conditions we are relying on indicators here. We just skipped over why each clause was S or a N condition.
Every Harvard student hates Yale.
Every
Harvard student hates Yale
S --> Y
/Y --> /S (If one does not hate Yale, one is not a Harvard student)
But hating Yale doesn't necessarily mean you're a Harvard student. You could just hate Yale because you dislike their mascot or they rejected you.
when a puppies owners leave, the dog cries
1.when
2.a puppies owners leave, the dog cries
pol, dc
pol->dc
/dc->/pol
Zombies can attack NYC all they want, the rent wont budge
"Where a dog eats a bone, a cat becomes bored"
LAWgic: If DEB then C.B
(If Dog eats bone then Cat Bored)

Is "each" also a sufficient indicator?
Another LSAT learning service includes it in their list.

I have a question: Can't the market not crashing be the result of many other factors, and not the facct that zombies are not attacking new york city?
but arent there other things that could cause the real estate market to crash? or in these types of aruments does that not matter?
