The Science of Deduction

Read this on my – Blogger.

Have you ever found a dead body or a crime scene and wondered what to do?
You call the police, obviously. BUT, by the time police or the ambulance arrives, what do you do? Stay away from the body? Or examine it yourself?
Most important thing first, – you need to be FAST. Fast in your reasoning, fast in taking action. The Science of Deduction is what makes you think fast and act fast on your deductive reasonings. The better you’re at it, the faster you deduce and act. The Science of Deduction is what I will be teaching you here.


First, lets split deduction into points that you will need to remember and notice in real life.
1. Awareness – If you’re half asleep then slap yourself to get your brain to think straight. You need to be aware of what is going on around you, make sure of the condition of the victim, if you’re 100% sure he is dead, call the police, 1% chance he is still alive? call the ambulance. Life comes first, you can deduce all you want later but if the person is still alive then you need to make sure he does not die. Use your first aid knowledge, I will only talk about a stabbing case because it is probably one of the most used ways of killing without making loud noise. So if the person is stabbed then don’t pull the knife out, get a blanket if you can find one, or anything else to put on the victim to warm him up to get his temperature back to normal (Shock results in temperature of the body to fall). If the stab is on the upper part of the body then place the legs on anything so they are on a higher level than the upper body. This will increase blood flow near the stab area and will help till ambulance arrives. Almost 99% of the times, the criminal is caught as soon as the victim opens his eyes back so don’t bother chasing or finding the criminal if you think you can save the person’s life. Stay with the victim and perform proper first aid.

2. Deduction – If the person is dead and you’re sure of it then call the police and until they arrive, begin your deductive reasoning. If you think that the crime has been commited just recently a few minutes or seconds ago then if you’re in a crowded place such as a park or public place and the crime was commited there without anyone noticing then do all you can to quickly get all the exits sealed. Criminals would commit a crime at such a place only because it is easier to blend in later and get away before the police arrives. After you’ve made sure all exits are sealed, begin your deduction. Never theorize on false data. You must have solid points before you theorize. “It is a Capital Mistake to Theorize before you have any data, it biases the judgement.” (-Sir A. Conan Doyle). Think of it like solving a maths problem, example: if X = Y and Y =3, then X = 3, or Ken is the writer of this blog, the creator of this blog is the writer, thus Ken is the creator of this blog. Notice the blood marks around the scene, you’re not a professional but still blood will speak a lot of things to you. Notice the palms of the victim, are they holding on to something? do they look like they were holding onto something? These are the things you should be paying attention to. If there is no blood on the scene, still there are chances that it was a murder than the person collapsing due to some illness. Smell the lips of the victim, do you smell something sour or a smell of Almonds ? if yes then it poisoning that caused the person to collapse. BEWARE, if you do smell any of the two I mentioned then do not smell it for long. The smell comes from the poisonous gas which is released after the poison goes into stomach and reacts with the acid from the gastric fluid. If you smell too much then you can get poisoned as well. Other than smelling, there is probably no other way to figure out poisoning without proper equipment. If you’re sure it’s poisoning then try to keep an eye on all the people nearby, maybe one of them will try to dispose of some poison if he had not done so still.

3. Evidence and Conclusion – All the evidence will always show some type of connection. If you see no connection then you have deduced wrong or have missed some important clue. I have already talked about the things you will need to pay attention to at the crime scene and from those things you will find your link of connection along with some evidence which will finally lead to conclusion.

If you follow all of these steps and are facing a simple enough crime, then the chances are that you will solve it even before the police arrives. Even if you don’t then chances are you will either be able to save the life of a person or you will be of great help to the police in solving that crime. That is all for this post.
