Hey, I'd be interested :)

Hi!

I also struggled a lot with flaw questions until it just starts to make sense. Just like you said I also learned the common flaw types, but I feel like it takes a good amount of practice for your brain to start to really recognize those patterns through convoluted language. Definitely a lot of practice has helped me and also identifying the conclusion and asking why?and trying to see why the premise falls short in support of the conclusion. You should really take your time with the stimulus and force yourself to predict the AC before looking at them and after doing that so many times it becomes sort of automatic.

Hey, you are correct that "no" is a group 4 indicator and the correct translation of it is negating the necessary condition. However, in the example you gave "no action is based on good intentions are justified unless they also result in success" as you also mentioned contains group 3 negate sufficient indicator "unless". As a rule of thumb, where there are 2 negations, they just cancel each other out, therefore, you can just diagram the statement as justified -> successful which the contrapositive is going to be not successful -> not justified. Hope it makes sense!

How do you negate the ac(c)? some replaces not all?
