Structure an explanatory argument, when it would be loyal to do so, as follows: the first premise states that if the explanation is correct, then a specified outcome of it will be observable; the second premise states that the outcome has been observed; and the conclusion states that the explanation is thus correct. It included an account of the physical laws that govern the interactions of the planets, stars, and other heavenly bodies. Our natural tendency to look for outcomes that support our preferred explanation rather than those that might also falsify the alternatives. Is the if-clause offered as superior to alternative explanations of the then-clause? [6] The probability of two consecutive years of success is no higher than .50 times .50, or .25. How does Abbys conclusion fare in the face of this alternative explanation? The plumber couldve called the man or sent a note (enclosed, perhaps, with his bill) to straighten things out, but wrote Dear Abby where there was a good chance it wouldnt be published or the man wouldnt read it; how often does a well-intentioned person take such an ineffective action to right a wrong? 4) Regulation and homeostasis. c. Aggression sometimes facilitates performance and sometimes does not. I know of some people with cancer who smoke. [Hint: First find P2P^2P2. There are, however, several helpful strategies that you can follow in making your judgment. A. Ideally, the explanation contains a cohesive and cogent understanding of the origins of the problems, the conditions that perpetuate them, the obstacles interfering with their solution, and the resources available to address them. It includes the presumption of causation. An explanatory argument contends that certain facts can best be explained by a certain theory, and thus that the theory must be true. If comets were common in December, then the premises of the argument would have still been true, but they would have given us no good reason to believe the conclusion. Thousands of lives are going to be wrecked over this. At least one source of income was going to be wrecked. a. athletes view aggressive acts that would be judged inappropriate in society in general as more appropriate in the sport environment WebWhich of the following is an explanatory hypothesis? The second part of the total evidence condition focuses on the probability of the explanation. And chivalry didnt make the difference, the researchers say, since women got no more food than men. My heads-tossing student may have been skillful, or she may have gotten lucky . Researchers found that during a three-year period, the percentage of tickets, compared to simple warnings, was considerably higher during the night shift: more than 71 percent of the drivers stopped at night got tickets, compared with 58 percent of those stopped during the day (the others got warnings). Second part: Reasonably high prior probability for the explanation; the causal mechanismnatural selectionis fairly well understood, and no alternate seems more likely. The second premise states that the observable outcome is known to have happenedthat it has been observed. Oona wants to conduct research on personnel management, workplace environment, and what type of environment results in high levels of employee productivity and efficiency. WebA hypothesis is a potential answer to the question, one that can somehow be tested. WebShort Answer. How often do plumbers waste time by doing things such as drying their clothes when they can make more money by going on to another job? The achievement is all the more remarkable when you consider that the mysterious sculptors created their masterpiece millennia before the existence of their subject. The only difference is that Geller claims that he is not using deception. Explanatory Impotence Explanatory impotence is the opposite of explanatory power. Lack noticed that on an island shared by two species of finches, ones beak was markedly smaller than the others. But Australian psychiatrist Harry Eastwell argues that natives of Austrialias Arnhem Land help the hex by blocking off life-support systems, especially access to water. Step 2. unintentional aggression. You can now see that you squandered your one opportunity. Wilhelm Wundt, Sigmund Freud, Noam Chomsky. If you evaluate the probability of the appearance of the comet but include in your background evidence the assumption that Newton is correct, then (setting aside the problem this would probably be the fallacy of begging the question) the probability of the 1758 comet would be very highit is, after all, derived from the Newtonian explanation as its outcome! Which of the following refers to a broad explanation or group of explanations for some aspect of the natural world that is consistently supported by evidence over time? Simplicity contributes to epistemic probability, so ask whether the explanation is sufficiently simple. Blue jay reproduction rates were measured in both habitats before and after the treatment. For exactly the same reason, we can hardly consider astrology to be supported when someone finds that the days horoscope has some truth in it; horoscopes are worded so vaguely that there are almost always events that can be interpreted as making them true. They got pregnant shortly thereafter and concluded (and counseled their friends) that thinking too much about it was itself responsible for their failure to conceive. But the theory of plate tectonics eventually provided a conceptual framework for continental drift, and the explanation no longer has an unacceptably low prior probability. More precisely, the condition is that the prior probability of the observable outcome must be sufficiently low. Carl Hempel, The Philosophy of Natural Science. As we have seen in the preceding chapters, the conclusion of a strong induction must fit both the premises and the available background evidence. e. as a linear function, The general aggression model proposes that the probability of aggression increases because of But Grayson believes its unlikely such factors fully explain the statistics. In another type of distinction, some explanatory arguments are general, given that they have application to a wide range of possible observable outcomes; others are singular, in that they apply only to a specific outcome. It is doubtful that more than 1 in 30 is able to win five years in a row on the basis of skillthat is, the probability of succeeding for five years by skill is probably no better than the probability of doing it by chance. To be useful in the scientific method, an observation must be: Despite all the intellectual analyses the scientific method gives rise to and objective conclusions it makes possible, it CANNOT. Proponents of the paranormal seized on them as new evidence of visitations from other galaxies; said one Patrick Delgado, author of several profitable books on the subject: No human being could have done this. 2003-2023 Chegg Inc. All rights reserved. until police arrived and took him into custody. A professor at Bath University in England combines this rationalization with the idea that psychic powers work backward and forward in time; he suggests, in apparent seriousness, that the failure of attempted experiments to prove psychic forces is actually evidence in favor of parapsychology, since skeptics reading about successful experiments afterward actually project their skepticism back in time to inhibit the experiment! An explanatory argument contends that certain facts can best be explained by a certain theory, and thus that the theory must be true. Suppose, for example, that on a camping trip to the mountains you say to your friend, This pot of water boiled quickly at this altitude; so all water boils quickly at this altitude. The premise and conclusion are both about the boiling of water at this altitude. Real estate investment trusts (REITs) experienced a record level of profitability in 2004 Soles Far worse than the plumber explanation from Dear Abby, it requires a long list of independently improbable things all to be truealternative ways, for example of accounting for the following: the vast documentation rescued from the German Archives; the elaborate sealed rooms set up for funneling the prisoners to their deaths; the movement of enormous quantities of asphyxiating Xyklon B gas to the death camps; the photographs of mounds of bodies; the vast body of eyewitness testimony by both victims and their murderers; and the otherwise mysterious disappearance from history of millions of Jews. A) experiential method B) scientific method C) intuitive process D) strategic management process E) account planning philosophy B) scientific method Alternative explanation that already exists. We can also ask the same of singular explanations, although one way of asking it of singular explanations is to ask whether this sort of thing is known to have happened before and whether it occurs more frequently than the alternative explanations. One emphasizes the power of suggestion as a psychological process; if faith can heal, despair can kill. Newtons theories, for example, while applied here to Halleys comet, actually cover the motion of all objects at all times. Then NASAs Donald Bogard compared the meteorites fingerprint of noble gases to those found on Mars by the Viking landerand discovered that they matched closely. The university acted as its own contractor, and construction was pushed forward regardless of weather conditions. This interpretation of the saying is unfalsifiable and can receive no logical support from the nature of ones experience. Which system accumulates the costs for each department or process within the factory? I found a Thai restaurant and now I go there for lunch every day. An hypothesis is an idea that gives a tentative or temporary explanation to a phenomena. As with the other argument forms introduced in this text, there are a variety of alternative terms for explanatory arguments, none of which seems to have taken the lead. Groups are kept as similar as possible and are treated identically, except for the variable of interest. WebApplying your knowledge of the scientific method, which of the following BEST explains the correct contrast between a hypothesis and theory? I saw the sagebrush and the grass wiggling and starting to shake, and I thought, Earthquake.. MUST: Why would you try to persuade your friend of something you have both just agreed is true? c. aggressive play is discouraged by coaches and parents Null hypothesis : this is known as the default hypothesis.It states that Repression is the mechanism by which we push out of awareness and into our unconscious memories of deeply traumatic childhood experiences. WebSchedule 1 - Dictionary . In some explanatory arguments, the explanatory theory is first invented, then the observable outcome is predicted and looked for. 1. [5] A graph of these results, representing our evidence in this case, looks like this. The conceptual framework was eventually supplied: the most important causal mechanism behind it is gravity, and, according to the eventually well-established Newtonian laws, gravitys pull on the air molecules decreases regularly as distance from Earth increases. 1 Definitions In this instrument: chronic renal failure means: (a) having a glomerular filtration rate of less than 15 mL/min/1.73 m 2 for a period of at least 3 months; or (b) a need for renal replacement therapy (dialysis or transplantation) for treatment of complications of decreased glomerular filtration rate Aggression is detrimental to performance. All of these. The explanations prior probabilitythat is, its probability prior to judging whether the observable outcome is truemust not be implausibly low and it must be higher than that of the leading alternative explanations. In a research study, any condition applied to subjectsthose in the treatment groupthat is not applied to subjects in a control group. When we compare frequencies we see that the prior probability of each portion of the plumber explanation is quite low; and the conjunction of all portions (recall Chapter 10this requires that the probabilities of all the parts be multiplied) is far, far lower. e. Raise the level of coaching, with an emphasis on fair play, especially with younger athletes. Resist the temptation, especially when you can see that coincidence has not been ruled out as an alternative explanation. Hundreds of people gathered for a second night Wednesday to see an image described as the outline of the Virgin Mary on a wall of an empty house in Hanover Township, Pa. Develop an action plan. The experimental subjects do not know which (if any) treatment they are receiving. It must be emphatically added that the world is in many ways mysterious, and that science can be mistaken, and often is. A form that cannot pull any of the load in a deductive argument may nevertheless pull a share of the load in an inductive one. You never talked about him like he was a heronever made any effort to keep his memory alive with letters and pictures. b. Which of the following is NOT a useful step in resolving peer conflict (especially in teenagers) in a nonviolent way? her own conscious experience. The magazine reporting it is reliable, and there is no reason to distrust it in this case. My evidence? B. For example, our hypothesis in this case could be that the toast didn't toast because the electrical outlet is broken. It is conducted to have a better understanding of the existing problem, but will not provide conclusive results. There was no control group with which to compare his patients who received the treatment. a. William James was the ________. Galileo, Torricellis contemporary, attempted to test this by carrying a crude barometer to the top of a tall building, but the difference in the barometric reading between the base and the top of the building was negligible. If Newtons account of celestial mechanics is correct and applies to the motion of comets, then a comet with an orbit similar to the 1530 and 1606 comets will appear in December 1758. The explanation must be sufficiently probable. But if Halley was right about Newtons views, there would be detectable regularitiescertain comets would be found to follow fixed elliptical orbits around the sun. If the prior probability of the outcome is high, then we expect the outcome to happen anywayeven if the hypothesis is false. d. Frustration produces physical but not psychological aggression. If the answer is yes, then the argument is at least moderately strong (assuming it has not failed the first part of the total evidence condition). With total restriction of fluids, death follows in 24 hours. Now its been discovered that the icebergs are broken pieces of huge ice shelves that are hundreds of years old, according to a study reported in the, Death and disaster provide a convincing argument that, contrary to the persistent notion, women are not the weaker sex. It is much harder to invent an explanation that successfully predicts future observations. If a researcher uses the same experimental setup as another study to collect data, but uses different research subjects, it is considered. Neither of the two alternatives has been ruled out, and either is more probable than that she is one of the very few people who has perfected special coin-tossing skill. The plumber says he went to a house, while the man says he lives in an apartment; how often does someone make that sort of mistake? To put it more generally, to say that an explanation or an outcome is unfalsifiable is to say that any observation at all is consistent with the explanation. Statistics and Probability questions and answers, Which of the following is an explanatory hypothesis? For each of the passages below, (i)state the observable outcome and (ii)offer a different observable outcome that would rule out alternative explanations and lower its probability, thus making the argument logically stronger. 1& 0\\ This is a dirty trick. Lucy wants to study changes in cognitive skills, moral reasoning, and social behavior across the lifespan. Webe. Some writers refer to this as the surprise criterion; it tests to see if you would be surprised by the outcome were you not to assume the explanation. Psychoanalytic theory focuses on ________ and early childhood experiences. Examples of this abound, even in some of the most widely accepted explanatory theories. Sample exercise. It is the best understanding that we have of that part of the natural world. But the extremely high prior probability of the outcome renders the argument logically useless. Suppose I say to you, If he is from Chicago, then he is from Illinoisand he is indeed from Illinois, so he must be from Chicago. You cant be absolutely sure without some wider context, but it normally wouldnt make sense for me to explain someones residency in Illinois by pointing to his residence in Chicago. Punishment motivates learning better than does reward.. For general explanations, a good way to check for simplicity is to ask. The Total Evidence Condition for Explanatory Arguments. If the prior probability of the explanation is extremely low and coincidence has not been ruled out as an alternative explanation, judge the logic of the argument to be weak. If the Earth is surrounded by a sea of air that decreases uniformly in pressure as the altitude increases, then Periers barometer reads 30 inches at 0 feet, 28.7 inches at 1,300 feet, 28.2 inches at 1,800 feet, 27.2 inches at 2,800 feet, and 26.2 inches at 3,800 feet, and 25.2 inches at 4,800 feet. An explanationalso termed a theory or an explanatory hypothesisis, for our purposes, loosely defined as a statement that enables us both to predict and to better understand the cause of that which it explains. Young women purchase fewer meats than women who are 35 years of age or older. Unlike the case of Halleys comet, the observable outcomesa blue anchor on his hand, a military carriage, regulation side-whiskers, an air of commandare where the reasoning begins. Life is organized on many levels within individual organisms, including atoms, cells, tissues, and organs. Bring it all together by fully clarifying and evaluating the explanatory arguments in each of these passages. It makes no statement with respect to causation. D. It excludes the presumption of causation. The train of reasoning ran, Here is a gentleman of a medical type, but with the air of a military man. Not too badly, if we compare the frequencies of each. B. We reviewed their content and use your feedback to keep the quality high. Consider the alternative that someone has accidentally dialed a wrong number, only to hang up when hearing an unfamiliar voice on the other end. The opposition has annoyed them. Slightly less oxygen means that we get tired a little sooner; slightly worn brakes stop the car a little more slowly; slightly less sunlight means the plant grows a little shorter. Then state whether it is general or singular and whether the explanation or the observable outcome came first. Just like the coin-toss and mutual fund cases, coincidence does make sense and is at least as likely here as the paranormal. WebIntrospection refers to a process by which someone examines ________ as objectively as possible. WebSchedule 1 - Dictionary . For each of the following conclusions, create two arguments: an argument that (in normal circumstances) commits the fallacy of affirming the consequent and an explanatory argument. The independent variable is manipulated to cause-effect on the dependent variable and the dependent variable is measured to examine the effect This makes good sense, because the probability of the explanation after you make a judgment about the observable outcome would roughly be your assessment of the soundness of the argument and it is too soon to make that judgment. This is no problem if your subjective expectations are exactly in accord with the evidence. A) experiential method B) scientific method C) intuitive process D) strategic management process E) account planning philosophy B) scientific method a person's unconscious. Which of the following exemplifies the unconditional positive regard component of client-centered therapy? Step 1. Why, that he was a retired sergeant of Marines. . 16. But where either species lived by itself on an island, it developed a beak in between these two extremes.
