When established scientists reject offbeat theories, defenders of such views love to cite these cases. Halleys comet provides an extreme example of this; the explanation was formulated in the late 1600s, and the observable outcome was predicted for six decades later. Theories are hypotheses that have been proved. Note: See Section 6. When have you had to convince someone to do something? But, as Hempel suggests, that is not all they requirethey require imagination. Statistics and Probability questions and answers, Which of the following is an explanatory hypothesis? A theory predicts events in a broad, general context; a hypothesis makes a specific prediction about a specified set of circumstances. Theories are hypotheses that have been proved. Newtons theories, for example, while applied here to Halleys comet, actually cover the motion of all objects at all times. As a useful standard, apply the surprise test by asking whether the outcome would surprise you (assuming you reserved judgment about whether the explanation were true and whether the outcome had been observed). d. fans become more aggressive under the influence of alcohol 1. b. fans become more aggressive after watching violent contact sports An hours sleuthing eliminated the plants inventory, machinery, welding operations, painting procedures and conveyor system as possible sources of the dent. What was the primary conclusion of Stanley Milgram's obedience research? A. Young women purchase fewer meats than women who are 35 years of age or older. 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. This represents the major premise of which theory? She is a ________. b. punishing all aggressive play Thanks for the example to W. V. Quine and J.S. It is much harder to invent an explanation that successfully predicts future observations. Which of the following statements is CORRECT? All of the following are elements of biological literacy EXCEPT: Having read the most important books in biology. Exploratory research is defined as a research used to investigate a problem which is not clearly defined. Further, it is not necessary for the prior probability of the explanation to be high; if the explanation were already highly probable, there would be no need for the argument! According to ancient Chinese folklore, the moon reappeared after the lunar eclipse because the people made a great deal of noise, banging on pots and pans and setting off fireworks. The Total Evidence Condition for Explanatory Arguments. An intellectual activity, encompassing observation, description, experimentation, and explanation of natural phenomena. 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. And chivalry didnt make the difference, the researchers say, since women got no more food than men. b. behavior directed toward the goal of harming a person who is motivated to avoid such treatment 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. b. WebA hypothesis is a potential answer to the question, one that can somehow be tested. This is the place to ask about coincidence as an alternative explanation. 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). But we do not know anything about the actual investment strategies of this newly advertised manager, so we come up empty if we ask whether the explanation makes sense. General explanations are typical of science, though are not restricted to it. c. social learning theory Record the facts. e. modeling, c. an interaction of situations and personal beliefs, The general aggression model proposes that when aggression occurs, it will be Complete each e. instrumental-reactive aggression theory, According to more recent research by Anderson and Bushman, aggression ranging from instrumental to reactive should be viewed Epistemic probability, as explained in Chapter 9, refers to the probability of the statements truth given all relevant available evidence. . If an explanation does already exist, then the outcome has a high prior probability and the argument is logically weak. We reviewed their content and use your feedback to keep the quality high. My wife claims she doesnt know what happened to it. 6) Evolutionary adaptation leading to descent with modification over time. It must generate testable predictions. So the logic of the burglar argument is shown to be weak. You might be impressed until you learn that I asked all 30 students in my class to stand up and try to toss heads. As with our other inductive arguments, the total evidence condition for logical success has two parts. Find three images of sound in the poem and three instances of silence. In Arnhem Land, it seems, sorcery kills not by suggestion or paralyzing fear, but by dehydration. d. revised frustration-aggression theory There were 15, then 8, then 4, then 2; then, after the fifth toss, this one student remained. During the previous winter MIU had been involved in a major construction project (a domed structure for the practice of levitation). As with the outcome, the concern here is also with prior epistemic probabilityin this case, the probability that you would assess to the explanation prior to your making any judgment about the observable outcome. WebTranscribed image text: www.bbt.com Our Time.com Cesearch Foundations, Process, and Ethics Savod Which of the following is an explanatory hypothesis? Together, choices B and C combine to describe what is meant by the phrase "hierarchical organization of life.". Thirty of the 40 who died were men and, says Grayson, most of the male deaths occurred before that of a single woman. e. Follow up. This argument would have the same form as the first one, differing only in the nature of the observable outcome. b. when participants are embarrassed The survivors were the finches with beaks closest to either of the two extremesa demonstration of how competition eliminates intermediate beaks and forces each species to specialize in seeds of one size. Applying Newtons laws to these data, he boldly made the following prediction: A comet with an orbit similar to the 1530 and 1606 comets will appear in December 1758. Why does this fall short of qualifying as an example of the scientific method? Simplicity can be a significant contributor to the probability of an explanation. Explanatory/ Causal /Bivariate Hypothesis. (The Vitamin C example is similar; one reason that researchers have not worked harder at collecting evidence for the theory is because it is unclear how it would work. Scientists generally base scientific hypotheses on previous observations that cannot satisfactorily be explained with the available scientific theories. Psychoanalytic theory focuses on ________ and early childhood experiences. Which of the following has scientific investigation shown to be LEAST reliable in criminal prosecutions? In this statement Stern clearly indicated that _________ morality would not be accepted or tolerated. Often, however, the chronological order is reversed; the observable outcome is observed, then the explanation fashioned in response to it. But you would have done far better to propose, Seven is not in the set. If you had been right, you not only would have confirmed your preferred even-numbers answer, but also you would have ruled out the whole-numbers alternativethereby improving the logical support for your answer. They want to show how tough they are. The line on the chart, I argue, does pass through the six plotted points but otherwise zigzags wildly, say, as follows. Which of the following statements is NOT one of their recommendations? One morning she wakes up after a late night reading and finds her vision is somewhat blurred; she immediately diagnoses optic neuritis. More subtle examples are easy to find. Until then, the argument is no better than a product of Keys own imagination. [6] The probability of two consecutive years of success is no higher than .50 times .50, or .25. There are two types of hypothesis. Pete McG. Many would argue that both the theory of evolution and creationism are equally probable because, after all, they are both theories. A theory with great explanatory power makes few assumptions, has significant predictive power and helps to reduce uncertainty in a precise and accurate way. Hierarchical organization. Some explanations will eventually measure up to the standards of good reasoning; that is no reason to eliminate the standards. 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. Fallacy of affirming the consequent. 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?. Science85. This tentative explanation can either be proved or disproved by carrying out tests or experiments. Simplicity contributes to epistemic probability, so ask whether the explanation is sufficiently simple. a. assertive behavior. 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. Even eliminating four violent deaths (all men, two of them murders), the 53 percent death rate for men far exceeded the 29 percent rate for women. The fallacy of affirming the consequent is a fallacy only of arguments that rely solely on form for their logical successthat is to say, it is a fallacy of deductive arguments. Sample exercise. causation. 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 Like their close cousins, inductive generalizations, explanatory arguments aim to expand our knowledge. B. Another contemporary of his, French mathematician and philosopher Blaise Pascal, suspected that Torricelli was right but that a greater altitude was required to prove it. General explanationsNewtonian celestial mechanics, for exampleare intended to apply broadly; Newtons theories explain the motion of all heavenly bodies at all times. It has long been my suspicion that, especially in Washington, when people say that they have read a book, they mean something other than attempting to glean meaning from each sentence. If the man were a Marine sergeant, then he would have a maritime tattoo, a military carriage, regulation side-whiskers, and an air of command. Just like the coin-toss and mutual fund cases, coincidence does make sense and is at least as likely here as the paranormal. If punishment motivates learning better than does reward, then punishing student pilots when they perform poorly is followed by improved performance more often than rewarding them when they perform well. a. assertive behavior. [5] A graph of these results, representing our evidence in this case, looks like this. Suppose I have heard that vitamin C prevents colds; I dont know whether to believe it but decide its worth looking into. No. Is the if-clause intended to provide a better causal understanding of the then-clause? b. How to Think about High Enough Prior Probability of Explanation. b. along a continuum D. It excludes the presumption of Living organisms are able to respond to stimulisuch as light, moisture, or another organism. Sales of vegetarian foods vary by season. When it did come true, it was often counted as reason to believe that the oracle had special powers. And so I do. Why would a scientist choose to state their hypothesis as a null hypothesis? Null hypothesis : this is known as the default hypothesis.It states that Statistics show that almost half of those who win baseballs Rookie of the Year honor slump to a worse performance in their second year. A Guide to Good Reasoning: Cultivating Intellectual Virtues, Creative Commons Attribution-NonCommercial 4.0 International License, The Total Evidence Condition (1): the Improbability of the Outcome, The Total Evidence Condition (2): the Probability of the Explanation, [If we are well above sea level, then water boils quickly.]. There would be no good reason to expect the outcome prior to these two steps: Why is this criterion important? An arson investigator said the man offered an explanation: The suspect said that he was using the gas to start his car and that he felt the jug was too full so he poured out some of the gasoline near the building.
