Help with Flaw Type Examples

Hey everyone, I am having a hard time with Flaw Questions. I know we are supposed to memorize the common argument flaws but that is where my struggle is. I am very much a visual/example type of learner. When going through the flaw types I realized it would really help me to understand and memorize them if I had examples. So I have been going through PTs and Drills that I have done trying to match them up with the flaw types and could use some help. Some I am able to easily match up to the type of flaw and others I am not. I have listed the different types below, some have specific question examples and then underneath I have a list of questions I need help matching. If anyone knows of any specific PT questions that match up with the other flaws please let me know so I can add them to my list. I hope this can also help others that struggle with flaws.

OMG. I want to kiss you right now
. I am going over flaw right now because that is a big weakness... can I just cry tears of happiness?

Hasty generalization-- like what happened over the past year is representative of what has happened forever.
Can you tell I just did PT30? Haha.
My thoughts:
PT39S2Q2 is a hasty generalization.
PT47S1Q8 is your argument fails therefore the opposite of your conclusion must be true
PT51S1Q10 is traditional fallacy/novelty fallacy
PT51S1Q15 is your argument fails therefore the opposite of your conclusion must be true
And I'm going to stop looking because I just realized that I haven't done PT 51+ yet lol.
Thank you!!! I edited my original post to add your changes and the ones you have questions about.
No worries! You helped a lot. Haha you can tell which PTs I did also. I tried to add some different ones but it's super time consuming and I think I was able to get a good variety of flaws.
Is there a specific PT range you want them in (below 50) or just in general?
No just in general. I just took examples from recent PTs I've done but any examples will be great.
Buckle in! I'll update as I find more...I know I've done most of these types before. Some of the ones I found are more flexible in terms of how they fit in but they give you the general gist.
1) Attacking the source of the argument (PT19, S2, Q14; PT25, S4, Q04; PT39, S4,Q11)
2) Uses terms unclearly/equivocation (PT53, S1, Q12; PT22, S2, Q24)
3) Analogies that really aren’t analogous enough (PT24, S3, Q02)
4) Appealing to authority in an area outside their expertise
5) Causation confusions (PT30, S2, Q25; PT47, S1, Q23; PT18, S4, Q9; PT39, S4, Q20)
6) Circular Reasoning (PT17, Section 2, Q2; PT17, S2, Q20)
7) Confusing necessary and sufficient conditions (PT22, S2, Q25; PT17, S2, Q11; PT17, S3, Q9; PT18, S4, Q3)
8) False dichotomy (PT22, S4, Q09; PT39, S4, Q26)
9) Confusing probability for certainty
10) Confusing "is" for "ought"
11) Percentages v. quantity
12) Surveys and samplings to reach a general conclusion (PT31, S2, Q03; PT39, S4, Q21)
13) Hasty generalization (PT18, S4, Q25)
14) Experiments to reach a general conclusion (PT35, S2, Q08)
15) Your argument fails therefore the opposite of your conclusion must be true
16) Relative v. absolute (PT 53, Section 1, Q22)
17) Confusing one possible solution for the only solution
18) Red herring (PT 18, S4, Q11; PT18, S2, Q04)
19) Tradition fallacy and novelty fallacy
20) Confusing part v. whole (PT 47, Section 3, Q25) I also describe this is as 'falsey transfers attributes that can't be transferred' (PT17, S3, Q19); (PT17, S3, Q16)
21) Beliefs v. facts
22) Relies on people's opinions as fact (PT28, S1, Q09)
Woooowww! This is so great thank you! I will go through them and update the OP so others can have a merged list. You're awesome!!
I once tried to make a list of all the common flaws.....But then I gave up.
So here is a partial list:
5) Causation confusions (correlation-causation flaws)
PT20.S1.Q10; PT20.S4.Q14; PT30.S2.Q25; PT31.S2.Q9 ; PT64.S1.Q5; PT65.S1.Q8; PT66.S4.Q25
6) Circular reasoning
PT6.S3.Q8; PT17.S2.Q2 ; PT17.S3.Q20; PT24.S2.Q8; PT49.S2.Q23
7) Confusing sufficient and necessary conditions (sufficiency-necessity confusion)
I think there is at least one sufficiency-neccesity confusion per PT.
PT17.S2.Q11; PT22.S4.Q21; PT23.S2.Q19; PT23.S3.Q17; PT24.S2.Q23; PT30.S4.Q14; PTJ07.S3.Q25; PT64.S1.Q24; PT67.S2.Q09; PT68.S3.Q21; PT79.S1.Q15
I don't blame you it's definitely a lot! That's where team work comes in. I am working on adding Nikita's and I will add yours as well. Thank you soooo much!
Thank you @keets993, @akistotle and @"samantha.ashley92". I have updated the OP.
If anyone else has updated for the flaws that have no examples or know the flaw types listed under match the flaw let me know
Match the flaw:
So these are interesting because they don't use 'key' words that we are trained to look for but you either have to; (1) look at the stimulus or; (2) parse out the english.
PT47S1Q23: Causation/Correlation
“ignores the possibility that an increase in theta waves may not always be accompanied by a state of profound creativity”
I haven't done 51 yet so I'll tag those later if they are still tag-less
PT67S2Q9: "a statement whose truth is required to be true" = necessary; "a statement whose truth ensures that the conclusion is true" = sufficient! I recently figured out (and was going to post about it to verify) that the second one is indicating a sufficient condition, beause when you affirm the sufficient it ensures the conclusion (assuming that conclusion is the necessary statement); either way its necessary/sufficiency confusion.
"treats a statement whose truth is required for the conclusion to be true as though it were a statement whose truth ensures that the conclusion is true"
PT67S2Q21: This is also sufficiency/necessity
"the argument fails to consider that bees might be present even in the absence of a particular condition that would ensure their presence"
I don't know if this is a 'common' type. It's basically stating that the argument is assuming that there is no other evidence that can be relevant to the issue. So, the person making the argument is assuming that they have all the facts/issues at hand and aren't overlooking something that could be used against them.
PT30S4Q8: "The argument presumes that no other evidence is relevant to the issue at hand"
PT30S4Q14: This is also sufficiency/necessisty. Ensures is similar to guarantees. Something that ensures that the conclusion follows = sufficient.
"It mistakes something that is necessary for its conclusion to follow for something that ensures that the conclusion follows"
Also, I think it's okay to put the question stem/AC in the discussion but not the stimulus.
To add to this list - #20 part to whole flaw: PT 62, Sec 2, Q 7.
This is really helpful thank you.
Does anyone have this on a word doc or spreadsheet?
I do. I'll send. Or, I'll try. PM me your email address.
You're a queen.
Okay this is AMAZING!!! Thank you so much. This just made my day
Wow, you people are amazing.
the helpful kindhearted queen jumped out
tysm for this
if anyone has this saved as a pdf/word doc lmk and I'll PM you my email x
I see some of these are still empty so you can add these to your list.
9) Confusing probability for certainty (PT54, Section 4, Question 16)
11) Percentages v. quantity (not a flaw question but RRE; PT39, S2, Q5)
Sorry I got a little behind on this but I have updated the additions from @keets993 and @LCMama2017
Thank you so much for sharing, this is so helpful!
this is great.
Bumping this, this is some great work!
This is so helpful! Thank you to everyone - and thank you @"Leah M B" for turning me on to it.
Beliefs v. facts
PT 58-4-14: "Fails to distinguish between the crime rate's rising actually rising and people's believing that the crime rate is rising"
Confusing part v. whole
PT 58-4-5: "Takes for granted that only the best management consultants have worked for the top management consulting firms"
I have one for red herring:

This should be bumped for how great of a resource it is.
Brilliant!
Incredible resource. Thank you, thank you, thank you.
If anyone has this byword document, please email it to me. Jackson.julien@yahoo.com. thank You.
Just commenting so I can find this post later but ya nice post!
Excellent Resource. It is extremely helpful for me to know what type of argument flaw you are dealing with when doing flaw questions. Thank you!
Heaven. Sent.
this is so helpful
bumping
Super helpful! Thanks for bumping!
Thank you all for doing this! Bumping
Thank you for bumping this
thank you
thank you so much! Adding the other two false dichotomy: (PT35, S4, Q13; PT38, S1, Q11)
this is a pretty old post and I did an updated one a couple years ago here: https://7sage.com/discussion/#/discussion/29425/flaw-types-with-example-questions-redux-2021-pandemic-cycle-version
I dont know that the author here is still active but feel free to send me the updates and I can add them to the other post
OR
Please feel free to copy the later version (which includes more examples) wholesale and make it your own. Maybe just keep attribution to the original - this thread.
Point being: keep this updated in some form and pass it on. None of us will be active here forever.
