ABSTRACT
Inferential reasoning is a central component of statistics. It is suggested that we should develop an informal understanding of the ideas that underlie inference before learning the concepts formally. This report is designed to help people to learn the concept of Abduction and Deduction in the context of the one and only consulting detective of all times Sherlock Holmes.
Criminal investigations, and trials, depend upon inferential reasoning. Theories, hypotheses and conclusions, are drawn from the evidences which are provided in the case. The victim's blood was on the knife; we supposed it was the murder weapon. The suspect's fingerprints are on the knife; we supposed he killed the victim. Sherlock Holmes, although a fictional character in 21st century, remains renowned as a great detective of all times. However, his methods, which were abduction and deduction, are used by many real detectives, is rarely described, discussed or researched. This report compares and contrasts the two forms of inferential reasoning which are deduction and abduction and the role of it in Sherlock’s work, and training of police officers by him.

The author wrote total 60 adventures which include 56 short stories that were self contained and 4 novels. This collection is known as THE CANON. Sherlock Holmes is fictional character who was a consulting detective. He was the first and only consulting detective in this world because he created the job title himself. Many television series, shows and movies were made on Sherlock Holmes after Conan Doyle first introduced him in “The study of scarlet.” He was a mastermind whose unreal and unnatural ability based upon his sharp skills of analyzing and observing a situation to gather evidence. He is known all over the world for his proficient use of deductive reasoning whereas using abductive reasoning to resolve tough and troublesome
The legendary fictional character Sherlock Holmes was constructed by a basis of a French criminal expert and a famous police investigator. He is known for his prowess in perception and analysis. On the other hand, Holmes sympathy towards people is near absent. Holmes loves to breakdown the story of each person he comes in contact with it. However, he does make a mistake occasionally. Although, there are many positive representations of Holmes, the Downey-Holmes is the best.
Sir Arthur Conan Doyle was a British physician and writer, mostly well known for his stories “Sherlock Holmes”, which are generally in the field of crime fiction. He was a prolific writer whose other works include science fiction stories, historical novels, plays and romances, poetry, and non-fiction.
Sherlock Holmes holds the Guinness World Record for “literary character most frequently portrayed on screen.” Over one hundred actors have played Holmes on screen. There are over two hundred and fifty movies, hundreds of episodes, and even plays based around Doyle’s writings with the first known Sherlock Holmes movie debuting in 1905. The first American Sherlock Holmes actor was William Gillette, who played him on stage in 1899 and on film in 1916 (Dawidziak, n. p.). The many adaptations make it very hard to
In Criminal Justice, there are many different detectives with many different qualities. So how do you know what it takes for a detective to be successful? What traits and qualities make a good detective? Today, two very popular detectives will be compared, Sherlock Holmes and Nancy Drew. These investigators are being “investigated” in one of their most popular novels, The Secret of the Old Clock by Carolyn Keene and The Hound of the Baskervilles by Sir Arthur Conan Doyle. Both of these novels have very good sleuths, with many similar and contrasting qualities. Let’s follow the clues in these books to figure out the qualities of these good detectives and what qualities will take most detectives down the path of success.
Crime is an unfortunate part of many people’s lives - both for the victim of the crime and also the suspect. There are many theories as to why crimes happen, who commits the crimes, and why crimes happen to certain people. Not all crimes can be solved, or questions answered but these theories give a peek into the thinking or background behind some crimes that are committed.
Logic Watson! Give me logic Miss Walden!" Not only was this man rude but he was also bossy; just what I needed in my life. At least his friend 'Watson' is nice enough. I wish they would really make up their minds, was it psychology they wanted or was it philosophy? Clearing my throat I spoke, "How about I get you a both, Sherlock if you don't mind telling me what you need this book for it would be a lot easier to help find you a logical selection." Sherlock seemed surprised to find someone complying so quickly after just denouncing a whole branch of science, one I found some truth in. "Well you see, I'm a consulting detective, the only one in fact, and John and I have a case regarding a man with what I believe to be 'Mommy issues' going around kidnapping single mothers. Please be quick about all of this, we need this information now!" Sherlock described. All the while he's describing this all the pieces are coming together for me, Sherlock, the curly hair, Watson, consulting detective: Sherlock Holmes the main all over the papers lately with that silly hate of
Sherlock Holmes, a creation of Scottish Author and Physician Sir Author Conan Doyle, is a fictional detective famous for his prowess at using logic and astute observation to solve cases. Sherlock is a very unique individual and he is so realistic that many people believe he was a real man existed in the late 19th century. In fact, Sherlock possesses a very interesting set of personality and his distinctive characteristics plays a big role in captivating the heart of the audience. So, who is Sherlock? What kind of person could draw many people’s attention?
So for an example, the investigator can say, this is a murder, the person was stabbed, and the motive was this person was caught having an affair. After the investigator comes up with his hypotheses he/she will then test it, if the evidence does not support his/her theory then he would start over on figuring out what, why and how it all occurred.
Sherlock Holmes is a well-known detective, deeply in which royalty has asked for his assistance in retrieving a photograph from Irene Adler. He is known for the excellence use of skills in solving crimes, of astute logical reasoning and of disguise. Holmes work has consistently involved
Sherlock Holmes uses many of the rules of inferences to come up with his conclusion. For my second example of abductive reasoning you could see it written out as; 1. Mr. Wilson wears an arc-and-compass breastpin. 2. If Mr. Wilson is a Freemason, then he would wear an arc-and-compass breastpin. 3. Therefore, Mr. Wilson is a Freemason. Simplified it would look like; 1. P. 2. If Q then P. 3. Therefore Q. This is the definition of modus ponens inference in math terms. Inferences can be turned into proofs by simply stating them in full sentences.
Additionally, epistemological assumptions pertain to how knowledge is obtained through investigating origins, structure, methods, and the validity of knowledge (Bohm & Vogel, 2011). Consequently, crime theories are based on the assumption that the world can be understood through science, that is, the human capacity to observe and to reason (Bohm & Vogel, 2011, p. 3). The last assumptions are metaphysical assumptions, which addresses the question of what is nature of reality (Bohm & Vogel, 2011). Furthermore, present in all criminology theory are two ontological assumptions, and the first assumption addresses whether human behavior is free willed or determined (Bohm & Vogel, 2011). Subsequently, the next assumption considers the inherent condition of human beings, or the condition of human beings in a hypothetical state of nature (Bohm & Vogel,
In all of Sherlock Holmes mysteries he uses observation and deductive reasoning to figure all of them out.
Sherlock Holmes is a character created by British author and physician Sir Arthur Conan Doyle, Sherlock is a legendary detective who solves even the most baffling and meticulously puzzled cases with astute observation, abductive reasoning and with little to no people skills. As a "consulting detective," he favors reason and logic above all else and rarely makes personal attachments beyond those that benefit him. He calls himself a "high functioning sociopath" because he does not make any acquaintance or understand emotions very well, beyond what can be studied.
The homicide scene introduces Holmes's incredible reasoning processes. In a search to figure out the answer to a death, the local detectives call in Holmes. The man, who had a boarding pass for a flight that crashed the day before, appears suspiciously dead in the trunk of a car. Within thirty seconds of investigation, Holmes's observations lead him to over four conclusions. As Holmes searches through the contents found on the dead man's body, the point of view is placed directly through Sherlock's eyes. His eyes focus on intricate
While there has been criticism of the Holmesian method of deduction, many people support the idea that the use of deducing people can help with capture of criminals. While Holmes refers to his findings as deduction himself many people say, “that the process that Sherlock Holmes engages in is usually not deduction” (Novella). Deduction is defined as using a logic method of assumptions based on general statements about the world (Novella). However, Holmes himself makes more of an educated inference on what he observes about the suspects and evidence in his surroundings. The term “Holmesian Deduction” has been used to distinguish the two different methods (Novella). Holmes most famous quote, “when you have eliminated the impossible, whatever remains, however improbable, must be the truth”, is often cited as the best definition to his method of deduction. While it is not a method commonly used now thanks to more advances in crime fighting methods and technology, Holmesian deduction has certainly influenced that way we look at a crime scene.
