This helped me remember: IN-ductive (as in the word IN-crease) is something that starts at something specific/small to explain something bigger/general (it "increases") DE-ductive (as in the word DE-crease) is something that starts at something general/big to explain something specific/small (it "decreases")
I have sifted through so many explanations of this and have always been confused. The way you semantically explain these topics are SO HELPFUL. This is an amazing concise way of understanding this. Thank you
Thank you so much Jacob for your appreciation. We hope that you understood the concept. We are glad that it was helpful for you. This really motivates us to do better.😊😊
Same, the struggles real with some stuff this course is throwing at me lol. Spending more time understanding the words in a question then the actual question itself!
"Mango is a fruit" and "all mangoes are fruits" mean exactly the same thing, but these sentences are considered to be both general and specific statements. I don't think that this video is as clear and great as everyone is making it out to be.
That's a great observation you have there. Actually "Mango is a fruit" and "all mangoes are fruits" would be quite a good example of deduction because that is literally what deduction is - just saying the same thing in different ways. A good analogy is having a jigsaw puzzle. You start with jigsaw pieces and once you finish the puzzle you still just have the same thing you started with - jigsaw pieces, but they have been rearranged. This video is arguably incorrect in its definition of deduction and induction. I say "arguably" because it uses a definition that is commonly used in various academic fields by people with an insufficient understanding of logic. The definitions offered in the video don't really offer value. Deduction is not reasoning from the general to the specific and induction is not reasoning from the specific to the general. In fact, you can use the exact same premises to draw inductive or deductive conclusions - it depends what you want. So, here is the actual (and meaningful) definition of deduction and induction: Deduction is any argument where it is claimed the conclusion is certain to be true if the reasons (premises) it is based on are true. Induction is any argument where it is claimed the reasons (premises) provided for believing the conclusion, increase the likelihood of the conclusion being true. I say "claimed" because you can have an invalid deduction (the conclusion does not follow with certainty based on the premises). Deductions are judged based on validity/invalidity and soundness/unsoundness. To be sound the deduction must be valid and the premises must be true. For an induction, you can have strong/weak arguments (depending on the support the premises offer for the conclusion) and cogent/uncogent arguments. A cogent argument would be a strong argument (premises make it highly likely that the conclusion is true) that also has true premises. Here is a real example of deduction: A B Therefore: A and B Or in words: I have a cat. I have a dog. Therefore: I have a cat and I have a dog. This is known as the "Conjunction rule of inference". Some things you will notice: 1. It reasons from the specific - and yet it is still a deduction. Deductions can have general or specific premises. 2. It doesn't offer any new information - deductions can't create new information because they are just revealing what is already indirectly known - they are drawing out the facts of the premises. 3. Note the conclusion (A and B) contains the premises (A, B) 4. You can judge the validity of the argument without knowing what the letters stand for based solely on its form. This is why deductive logic is known as also known as "formal" logic. Now let us make an induction: A B Therefore: C Or in words: I have a cat. I have a dog. Therefore: I like animals. Some things you will notice: 1. It uses the exact same premises as the deduction - I have just changed the conclusion to be an inductive one. Inductions can have general or specific premises. 2. The conclusion can still be wrong. Perhaps I hate animals and the only reason I have a cat and dog is because they were given to me by a friend and I don't want to offend my friend by getting rid of the animals. Or maybe I have kids and they like the animals. 3. The conclusion (C) does not contain the premises (A and B). 4. You can't judge the argument without knowing what the letters mean. There is no way to tell that A and B result in C unless you know their meaning. Final remarks. You might think to yourself that deduction is useless - given the conjunction example I gave you. But what you need to remember with a deduction is that it is made up of lots of small steps which are often obvious in isolation but they all add up to a none obvious conclusion. Eventually you end up with deductions that look like this: Starting premises: 1: If T then (B or E) 2: Not E and T So we can make the following deductions: 3. T and not E (Commutativity rule of inference based on premise 2) 4. T (Simplification rule of inference based on our deduced premise 3) 5. B or E (Modus Ponens rule of inference based on premise 1 and our deduced premise 4) 6. E or B (Commutativity rule of inference based on our deduced premise 5) 7. Not E (Simplification rule of inference based on premise 2) Therefore: 8. B (Disjunctive syllogism rule of inference based on deduced premises 6 and 7) I know you won't understand the argument I just presented, but I hope you can see that it is not obvious from the starting premises the conclusion is B. You needed to make lots of smaller deductions that add up the the final conclusion B. I hope this helped you.
I primarily think with deductive reasoning and I have a friend who primarily thinks with inductive reasoning. The issue is that she fails to realize her inductions are probabilities based on an educated guess. She mistakes her inductions to be true certainties. She has a lot of emotional biases from particular personal experiences that cause her to stereotype unfairly.
Youd be hard pressed to function in this world with primarily, or only, deductive reasoning. Many of the premises in deductive reasoning can only be reached by induction in the first place. Deductive conclusions require that the premises are inherently true by definition. In the video example "all fruits have seeds" is a premise that was reached by induction. It is perfectly possible that a mango could grow without seeds through genetic mutation, so the deduced conclusion required induction. Deductive conclusions are often useless because of this. You should already know the conclusion because it is necessary based on the established premises. Inductive reasoning is the foundation of pretty much all scientific investigation.
The other reply is right on. I will add that inductive reasoning leads to generalizations, which is exactly what early man used to survive. Think of how many lions you would need to run into before you concluded they are to be avoided unless you were hunting them, etc. Intelligent thinkers use inductive reasoning almost exclusively. How else could you make quick decisions, or life-changing choices?
Thank you for the great explanation! Question: Aren't the statements in the deductive model specific statements? Directly compared to the statements used in the inductive explanation, I see no difference. Please help so I can finally understand this!
2:12 this is an example of predicate logic but we know that statement 2 is false .... There exists some fruits which don't have seeds therefore premises is false so can't make sound argument
It's incorrect. There's a different between conclusion and assumption. If one "Concludes that the mangoes are anything without examining all of the mangoes then it fails to be a conclusion and remains only as an assumption.
No let me help you out here and make an easier example for you. When a woman has dated 5 men who have all cheated on her, based on just little sample from the billions of men in the world she can still make a statement that men are cheats. This woman has not examined all men or dated all men but she has concluded based on the few she has been with. Yes so it may sound like an assumption to you but that’s her truth that all men are cheats. So I literally get what you are saying but it still makes sense that inductive reasoning makes you generalize stuff based on few specifics you know.
Conditional reasoning is reasoning that involves statements of the sort If A (Antecedent) then C (Consequent). This type of reasoning is ubiquitous; everyone engages in it. Indeed, the ability to do so may be considered a defining human characteristic.
Mathematical induction is actually a form of deductive reasoning. Also It has been said that induction is a reasoning from the specific to the general. However, there are many inductive arguments that do not have that form, for example, 'I saw her kiss him, really kiss him, so I'm sure she's having an affair.'
Good point. But I think it's important to understand that the argument is incomplete here. If you follow the "rabbit rule", you'd see that the element "affair" (that's in the conclusion), is missing in the premises. You could frame it in multiple ways, e.g. "I saw her kissing him. People kissing are always having an affair. So, she's having an affair". It seems to me that this is a deductive argument. Don't you think so?
@@pazesantos No, it's not. Because not all people that are kissing are having an affair. You can, however, noticed that *most* people *you* have seen kissing are having an affair. Therefore, making the argument inductive.
@@pazesantos It's also possible that the argument OP provided here is an abductive reasoning. Which mean the conclusion is the explanation to the premise, not an extrapolation or generalization to wider samples. Another example of abductive argument: 1. _"I heard the door opened 5 at AM -> It's probably my husband that just returned from work"_ The argument here doesn't suggest that most people that hear the door open in the morning mean their husband return. It just states the best explanation to *her* situation. The same thing can be said for _"I saw her kissing him -> She's having an affair"._ There can be many other explanations. It might be an act, it might be forced, but the best explanation (according to OP) is she's having an affair.
These two reasoning types are essential. Science basic tenet is based on inductive reasoning. Whereas deductive reasoning, if premises are correct, the conclusion will always be CERTAIN. Much more powerful than science.
