creates gravity. And Premise B, is all objects have mass. Therefore, all

objects create gravity. Because if all mass has gravity and all objects have

mass, then they must create gravity. Notice that the logical conclusion has to

be true if the 2 premises are true. We know, however, that this type of

reasoning can lead to correct conclusions only when the general premises to

which they are based are true. Let's look at another example. Premise A,is I

don't know math. Premise B is, I can't learn math. Therefore, I shouldn't even

bother trying to learn math". We see, here, that this reasoning leads to a

false conclusion, because premise A is false. And so is premise B. So, even

though the argument is. Easily structured in the same way. One leads to an

accurate conclusion, and one, this one, does not. Deductive reasoning is what

scientists use when we make predictions for our general goals. Now let's go to

Susan and talk about inductive reasoning.
