WebA hypothesis (plural hypotheses) is a proposed explanation for a phenomenon. I saw the sagebrush and the grass wiggling and starting to shake, and I thought, Earthquake.. 5) Growth, development, and reproduction. Although there is no formula for deciding on the improbability of the outcome, there are some helpful strategies that you can follow in making your decision. In a short paragraph, identify the explanation, discuss why it may be unfalsifiable, and explain how this results in a problem with the first part of the total evidence condition. All 24 of his patients who received the treatment were healed. We do not have to establish the correct explanation to establish that the argument is a bad one. Young women purchase fewer meats than women who are 35 years of age or older. A relationship between variables in which they increase (or decrease) together. Please give like. But it is highly probable, whether my theory is true or false, that the reviews will be good or bad or somewhere in between. WebA hypothesis (plural hypotheses) is a proposed explanation for a phenomenon. I was being more careful about my health because I was engaged in the experiment. Not too badly, if we compare the frequencies of each. . P.S. . Thirty of the 40 who died were men and, says Grayson, most of the male deaths occurred before that of a single woman. What was the primary conclusion of Stanley Milgram's obedience research? Premise 1 is probably true. You never talked about him like he was a heronever made any effort to keep his memory alive with letters and pictures. Step 5. Appetite fails, and the relatives keep water cans beyond reach, despite temperatures well above 100 degrees in the shade. And it is highly probable that we will have any observation at all. Any unfalsifiable explanation is in principle unable to satisfy the improbable-outcome criterion and can never be the conclusion of a sound explanatory argument. 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! c. with the intent to harm psychologically. Explanations, to recall Chapter 2, are not necessarily arguments. The achievement is all the more remarkable when you consider that the mysterious sculptors created their masterpiece millennia before the existence of their subject. This helps to explain why so-called anecdotal evidence can be problematic. When people insist that they have no repressed memories, then, Freud considers this to be evidence for the presence of resistance, which is itself evidence for the existence of repression. OK, so shes not admitting to anything, but the next day when I went to get the pipe, it wasnt where I had put it! By using the control group, the alternative is ruled out that the effect is somehow induced by the test itself. Clearly, smoking causes cancer. It can also be helpful to know that when explanatory arguments occur in ordinary language, the ifthen premise is more often than not implicit (which tends not to be the case with the fallacy of affirming the consequent). Doing the math for five years, we find that the prior probability of the coincidence explanation is about .03that is, about 1 in 30 could be expected to have this kind of success just by chance. Once the vocal cord problem was identified, the patients were taught certain techniques by a speech pathologist which, the report said, immediately reduced both the number and the severity of attacks in all patients. For her part, Delynn Carter said she knows what triggered her attacks. In the steps of the scientific method, what is the process where a scientist writes down tentative explanations or statements about what he/she expects might happen under certain conditions? But in an Oregon State University study that was replicated several times, wild frog eggs were placed in 72 cages, some with filters that let all sunlight inside except UV radiation. If this turns out to be true, it provides much better support for the explanation since it rules out the gravity alternative. Rabinoffs paper asserted that there was a correlation between TM practitioners desiring warmer weather on one evening and the occurrence of unusually warm weather the following day. Webe. 4) Regulation and homeostasis. 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. This is what happened with Torricellis hypothesis. But the extremely high prior probability of the outcome renders the argument logically useless. Some historians mark this as the day of the final triumph of the Newtonian over the Cartesian theoretical tradition. I knew you came from Afghanistan. Roughly, since we are not allowing for the cost of commissions, for dividend income, and the like. It is conducted to have a better understanding of the existing problem, but will not provide conclusive results. c. reactive versus hostile He was a man with some amount of self-importance and a certain air of command. Penelope studies how the structure and function of the nervous system is related to behavior. 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. Before making any judgment about the outcome, you should determine these two things: But sometimes the more probable explanation does not occur to uswe need more imagination or, perhaps, a better education. B. The MIU supplier of concrete had required MIU to give one days notice of the need for concrete, but never agreed to provide it for the next day until first referring to the National Weather Service. 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. The planet is too dim to be seen, but the scientists said they are convinced it is there because the pulsar emits radio signals that vary in a way that can best be explained by the gravitational tug of a nearby planetthe waves are a bit early for three months, then for three months arrive a bit late. Sample answer. If you are like most people you suggest, Eight is in the set. And my reply is that yes, 8 is included, because I am thinking of the set of all whole numbers. No one can even begin to provide an account of the conceptual framework, of the causal mechanisms, that would make sense of it. \end{bmatrix} This is not to say dogmatically that magic cannot happen. It must establish an alternative explanation for a phenomenon. But where the two species competed for seeds, one evolved a beak suited for the small seeds, while the other developed a beak for the large seeds. Oona wants to conduct research on personnel management, workplace environment, and what type of environment results in high levels of employee productivity and efficiency. d. a and c In which of the following situations is aggression likely to occur? Falsifiability applies when there is some possible observable outcome of the theory that could prove the explanation to be false. Specialists found the cause by taking motion pictures of the patients vocal cords during an attack and during a normal period. The fact remains that she tossed heads, on demand, five times in a row, but you now realize that coincidence is at least as good an explanation as talentafter all, how many people can actually toss heads whenever they want?and you are likely to lose interest. We are the only two people in this apartment. Which of the following statements is NOT one of their recommendations? Here is one of the classic exchanges:[4], Dear Abby: Im a traveling man whos on the road five days a week. b. Sample exercise. Newtons account of celestial mechanics is correct and applies to the motion of comets. He decided to study the environmental impact of this herbicide on blue jay reproduction. When was psychology accepted as an academic discipline? a. how to be rough and tough without getting thrown out of the game. Aggression has been defined as which of the following? WebShort Answer. For any explanation you can ask whether it makes sensethat is, whether there is an adequate conceptual framework to account for the causal mechanisms required by the explanation. e. none of the above, b. behavior directed toward the goal of harming a person who is motivated to avoid such treatment, Smith's research concerning violence in hockey showed that Because the explanation does no work in making the outcome probable, it should get none of the credit when the outcome is observed. Again, the two sorts are subject to the same logical standards, though we can shape our inquiry a bit differently in each case. The Total Evidence Condition for Explanatory Arguments. It is much harder to invent an explanation that successfully predicts future observations. It makes no statement with respect to causation. Concrete, according to the campus architect, was poured whenever the schedule required and the necessary materials were available. WebQuestion: Which of the following is an explanatory hypothesis? After one of our couple friends started going to a fertility clinic, they just relaxed and stopped consciously trying to conceive. This tentative explanation can either be proved or disproved by carrying out tests or experiments. Singular explanationsthat the butler did it, or that the man was a Marine sergeantare designed to apply to a very specific thing or eventto this particular murder or to that particular mans physical characteristics. For a fullerand fascinatingaccount of Halleys reasoning, see Ronald Giere. In a randomized, controlled, double-blind study: Neither the experimenter nor the subject know whether the subject is in a control group or an experimental group. A deductive process based on testable and measurable events. Newtons theories, for example, while applied here to Halleys comet, actually cover the motion of all objects at all times. One other possible explanation is that as the pulsar spins it might be wobbling due to some strange effect in the inside of the star, though such an effect is not understood and has never been observed before. It includes the presumption of causation. The cages were then placed in the same spot where the frogs laid the eggs. Personal Finance Semester 1 Test - Mrs. Ellio, John Lund, Paul S. Vickery, P. Scott Corbett, Todd Pfannestiel, Volker Janssen, The Language of Composition: Reading, Writing, Rhetoric, Lawrence Scanlon, Renee H. Shea, Robin Dissin Aufses, Eric Hinderaker, James A. Henretta, Rebecca Edwards, Robert O. Self. It must generate testable predictions. Clearly in Afghanistan. Arthur Conan Doyle, There has recently been a startling decline in a large number of amphibian populations, apparently because UV radiation is harmful to them. Record the facts. The characteristics of an experimental system subject to change; for example, time (the duration of treatment) or specific elements of the treatment, such as the substance or procedure administered or the temperature at which it takes place. 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. Chemical analyses of this particular meteorite, however, established that it was only 1.3 billion years old and made of cooled lava. Because the observable outcome rules out the leading alternative explanations, its prior probability is far lower than the anecdotal argumentand thus the argument is logically much stronger. The first premise states that the theory, or the explanation, really does enable you to predict the facts, or the observable outcome. A pathway by which we can come to discover and better understand our world. Young women purchase fewer meats than women who are 35 years of age or older. An increase in family income leads to an increase in the percentage of income spent on housing. In this section we will look at the improbability of the outcome. Carl Hempel, The Philosophy of Natural Science. c. rewarding sportspersonlike behavior Favor outcomes for which no explanation already exists. Scientists rejected Newton, they rejected continental drift, they rejected meteorites, and they were wrong! Sample answer. The comet argument can be clarified as follows: The correct form for an explanatory argument should look familiarit is also the form of the fallacy of affirming the consequent, introduced in Chapter 11. Statistics and Probability questions and answers, Which of the following is an explanatory hypothesis? Be careful not to confuse explanatory arguments with deductive arguments that commit the fallacy of affirming the consequent. Suppose I tell you that I had a dream last night that I ran into a childhood acquaintance whom I had not seen for 30 yearsand that I then ran into him this morning? Could you find out for me which five days that man is on the road? All rights reserved. All of these. Gilbert Harman is associated with the phrase. An observable outcome for which there are fewer possible explanations is that much more improbableand, thus, is that much logically stronger. This hypothesis is not necessarily the right explanation. Which of the following has scientific investigation shown to be LEAST reliable in criminal prosecutions? Some explanations will eventually measure up to the standards of good reasoning; that is no reason to eliminate the standards. unintentional aggression. The explanationthat he was a Marine sergeantcomes next. As with our other inductive arguments, the total evidence condition for logical success has two parts. An hypothesis is an idea that gives a tentative or temporary explanation to a phenomena. Experts are tested by Chegg as specialists in their subject area. d. revised frustration-aggression theory More precisely, the condition is that the prior probability of the observable outcome must be sufficiently low. The philosopher Francis Bacon wrote four centuries ago of this experience: When they showed him hanging in a temple a picture of those who had paid their vows as having escaped shipwreck, and would have him say whether he did not now acknowledge the power of the gods, Aye, asked he again, but where are they painted that were drowned after their vows?. Favoring outcomes that rule out alternative explanations is an especially powerful strategy. A hypothesis attempts to explain natural phenomenon and can be tested through experimentation; a theory attempts to summarize a large expanse of natural phenomenon and has already been tested thoroughly without contradictory results. A comet with an orbit similar to the 1530 and 1606 comets did appear in December 1758. B. A. For the sake of illustration, I will slightly idealize the intermediate readings: say, it was 28.2 inches at 1,800 feet, then one inch lower at each of the next thousand-foot intervals. e. modeling, c. an interaction of situations and personal beliefs, The general aggression model proposes that when aggression occurs, it will be Can appear to reveal links between two phenomena that do not actually exist. Observable outcomewhat is explained in an explanatory argument; the observable outcome follows from the explanation and can in a certain way, at a certain time, and under certain conditions, be seen, heard, smelled, tasted, or touched. Explanatory arguments come in several varieties. This is solid evidence for the existence of the so-called sophomore jinx. The second part of the total evidence condition for explanatory arguments is this: the probability of the explanation must not be implausibly low and must be higher than that of the leading alternative explanations. And the argument concludes with the assertion of the explanation. From what Ive told you, what conclusions would you draw? But, as Hempel suggests, that is not all they requirethey require imagination. C. An increase in family income leads to an increase in the percentage of income spent on housing. Devise a testable prediction.
