Deductive and Inductive Reasoning Flow Chart: Valid vs Invalid, Strong vs Weak, Sound vs Unsound

[@katherinesherlock4864]

This really did help me so much! My exam is today and I have been religiously studying this video. You break it down in a way that was easy for me to understand and memorize.

[@LetsGetLogical]

Aww! My first "Super Thanks". Appreciate your support! Good luck on your exam today. 🙂

[@butterfly-xe4tf]

you just made me not regret for the whole week of me zoning out in class while my teacher was lecturing. I LOVE YOUR WORK AND YOUR VOICE.

[@Kiko355-]

agreed

[@christiangoran6621]

Thank you for this. 8 min explained it to me better than 9 hours of lectures has done so far.

[@e.cforest5422]

Try not going to a university. I completed the entire Logic and Critical Thinking COURSE in my online class in 7.5 hours and I take my test today. In person university is a waste of money.

[@24hrs_promise54]

I'm writing on fridday 😹💪hopefully it's gonna work for me too

[@Red-lm7re]

If you really think you learned here better than 9 hours of lecture, then you should stop studying logic. On a different note. Really, you just need the flow chart and you can understand this within a minute.

[@dkf28]

@@e.cforest5422 Could you recommend me a way to study Logic and Critical thinking without uni please ?? I am a scientific student and I want that skill to improve deduction skills, but I don't want to pay for that course.

[@hanhanhanool1738]

Great video! Love the examples provided for each. Many thanks

[@Andreatuzze]

this was the best video about logic I've seen so far thank you so much. Especially about soundness, so an argument to makes sense has to be sound. because it can work logically when it's a valid( or a tautology) but still making "no sense in the real world" because the premises are false. And finally all sound arguments are valid but not every valid argument is sound

[@LetsGetLogical]

Sounds like you got it. Right on! 🙂

Yes, many people find it difficult. You're not alone! If it turns out college is not for you, remember that many, many people carve out a good life for themselves in other ways. For instance, one of my friends is a plumber and another is a corrections officer. They both make much more money than I do. Best wishes.

[@sofe_9023]

2:04 can this example be an inductive reasoning?

[@LetsGetLogical]

Sure! Maybe the person is just trying to give *evidence* that Mary has a pet penguin. The fact that Mary's pet is black and white _does_ increase the probability that it's a penguin. So, yeah-this argument could be construed as inductive. (But note that it would be a _weak_ inductive argument. The mere fact that Mary's pet is black and white does not make it probable, all things considered, that it's a penguin.)

[@JTan-fq6vy]

Thanks for the great video! For inductive reasoning, I am curious how to precisely measure whether an argument is strong or weak? Any quantitative methods, such as causal inference, could play a role here?

[@LetsGetLogical]

Great question. The precision you're asking about is exactly what the discipline of Statistics is for. But in the case of everyday inductive reasoning, it tends to be just common sense ball park estimates of probability, nothing precise.

[@JTan-fq6vy]

​@@LetsGetLogicalThank you! Would you mind sharing some (introductory) books or references of statistical-based inductive reasoning?

[@LetsGetLogical]

Don't have any book recommendations off the top of my head but do a search on Bayesian reasoning and you'll have a fun rabbit hole to go down.

[@joodd6603]

Awesome vid, thanks for posting.

[@kobbygbena861]

How'd i distinguish between an invalid deductive argument and inductive argument. Still dont quite get it

[@LetsGetLogical]

Insightful question! Assume the premises are true. And they make the conclusion probable but _not_ guaranteed. Is it a successful inductive argument or a failed deductive argument? Answer: it depends! If the argument is put forward with the aim of guaranteeing the conclusion, then it is an invalid deductive argument. But if the argument is put forward with the aim of making the conclusion probable, then it is a strong inductive argument. "Valid" and "strong" are terms of evaluation. But they're evaluating different things. So in the case you're talking about, if we ask "Is the reasoning any good?" the answer is: "Well, it's a good inductive argument (strong) but a bad deductive argument (invalid)."

[@BobbyJ529]

When you're listening to an argument live do you automatically mark the premises and conclusions intuitively as they come up or is this something you still have to stop and think about?

[@LetsGetLogical]

Depends! But yes, sometimes it takes some work in real time to identify the premises and conclusion, especially with a wordy, unclear speaker (or author).

[@rejected4760]

I have been studying this topic lately. But I have issues with the definition of Valid. There are 10 animals in the barn. They are either cows or cats. There are not 9 cows in the barn. There is exactly 1 cat in the barn. This argument is not valid. However let's say the premise that there are not 9 cows in the barn is false. Then the conclusion must be true.

[@LetsGetLogical]

@rejected4760 Hmmm. I don't see it. Like you suggested, let's say the premise that there are _not_ 9 cows in the barn is false. And let's say it's because in fact there are 10 cows in the barn. Well, then it does _not_ follow logically that there is exactly 1 cat in the barn (because there are 0 cats in the barn). Or perhaps I misunderstood you.

[@rejected4760]

@@LetsGetLogical if the premise "There are not 9 cows in the barn." is false then tere must be 9 cows in the barn. so the conclusion has to be true that means the conclusion is guaranteed to be true if premise 1 and 2 are true and premise 3 is false. and since like you said the actual value of true or false does not matter, this argument should be valid. the 3rd premise is just negated and thats where my issue lies. just negate one premise and the definition of valid doesnt apply anymore

[@LetsGetLogical]

Doh! I missed the double negation of "It is _not_ the case that there are _not_ 9 cows in the barn." Ah, the dangers of trying to do careful philosophy on the fly in comment sections of YT. 🙂

[@andrewvirtue5048]

This video is misinforming the public. It is explaining deductive reasoning as taking two statements to gather a conclusion. That is INductive reasoning. Starting around 1:56. Deductive reasoning is taking the results to find the data. A breakdown into a conclusion. Inductive reasoning is a buildup into a conclusion; taking the data to find results.

[@LetsGetLogical]

@andrewvirtue5048 Thanks for dropping in. Appreciate your challenge. You sound like someone who is interested in this stuff, so I'd encourage you to take a look at some standard resources like the Stanford Encyclopedia of Philosophy or one of the common undergraduate-level logic books such as Hurley's A Concise Introduction to Logic, Copi's Introduction to Logic, or Herrick's Introduction to Logic (which is the text I use). I think you'll stand to benefit by comparing the view presented in these academic sources with your own view of inductive and deductive reasoning. Either by sharpening your own view, or coming to have a greater appreciation for how contemporary logicians frame these concepts. It's true the distinction can be characterized in different ways, but the characterization I give here is the most common.
