Deductive reasoning is a great way to develop a conclusion if you already have previous evidence. In deductive reasoning, the argument consists of two premises and a conclusion. If the premises are true, then it is impossible for the conclusion to be false, and visa-versa. An example would be:
Premise 1: Sam was killed with a blunt object.
Premise 2: Ten feet from his body was a bloody baseball bat.
Conclusion: Sam was killed with the baseball bat.
Detectives use deductive reasoning all the time as well as almost everybody, we just don’t realize it most of the time. Detectives use the information they have been given (premise one and two) in order to logically come up with a valid conclusion. Then after further testing, their argument or hypothesis is tested in the lab. For example, there is still a small chance that the blood on the baseball bat isn’t Sam’s, but we find that to be very unlikely. Let’s say it was Sam’s blood though, and we also found Dan’s fingerprints on the handle of the bat. We can use deductive reasoning again:
Premise 1: The fingerprints on the bat are those of the murderer.
Premise 2: Dan’s fingerprints are on the baseball bat.
Conclusion: Dan brutally murdered Sam with the baseball bat.
And boom goes the dynamite,

this was a great post melvin banner! The example at the beggining helped me to understand the intro even more. I clearly understood that by deducing what happened before the outcome you could already guess the outcome. It was a nice post to read because youre words flowed really well and the thoughts and statements were very clear. The way you tied the two examples together and brought them to reality was superb. You obviously understood this concept well and that really helped me understand it that much better after reading your posting. Also i always enjoy your sign out "and boom goes the dynamite" just a classic statment!

Melvin you did a great job explaining deductive reasoning. You did a good job explaining exactly what it's all about, as well as giving examples to make it more clear. Your examples are not only clear but they are funny, and it kept me interested. Before reading your post I was quite confused on what deductive reasoning was all about, but now I am completely clear on what it is now. Overall you did a great job, and it is obvious that your post are effective because big cat seems to think so too. Keep up the good work.
