Silver Blaze Deductive Reasoning

When Sherlock Holmes tries to figure out what happened to Silver Blaze, he did not go off of what people's opinions or rumors. Holmes used his logic of where the possible places the horse would go after running away. One by one Holmes eliminated all the possible places Silver Blaze could have went until he eventually finds the horse at Mapleton. Sherlock Holmes said "When you have eliminated the impossible, whatever remains, however probable, must be the truth." People have difficulty separating their own opinions/theories when trying to figure something out.
For my personal experience, sometimes I lose my wallet and I used to struggle with finding it but now I use deductive reasoning to find it. First I check all my pockets, and if it is not in my pockets then it is either in my backpack or in my room. I check my backpack next and realize that it must be in my room. I then find my wallet sitting on my desk in my room.
