It isnt possible to say with precision how improbable the outcome must be to count as sufficiently improbable. But the first one, Torricellis, has a higher prior probability because it is simpler, due to its prediction of a smoother curve. . It was a tiny dent, no larger than a nickel, on the main frame of one motorcycle moving along an assembly line that produces about 175 such vehicles every day. 1. Further, we suppose that causal mechanisms operate uniformly in the worldthat under similar circumstances they operate similarly, and that slight dissimilarities in circumstances tend to produce slight dissimilarities in the way they operate. In other words, it means that you cannot use all of the relevant available evidence in making this particular judgmentyou must exclude the assumption that the explanation is true, and you must exclude observations that might have already been made in the attempt to verify premise 2. But the more moving parts a machine has, the more likely it is that it will break downso a well-designed machine includes no more parts than absolutely required. For each of the arguments below, offer an alternative explanation that already exists, which thus renders the outcome probable and the argument logically weak. a. many coaches, parents, and teammates accept and reinforce the modeling of aggressive acts b. violence is modeled by young amateur hockey players Males exhibit higher levels of aggression than females.

So the scientists are wrong when they reject the paranormal, ancient astronauts, and homeopathic medicine! But eventually, confronted by many cases in which there seemed to be no medical reasons for deaths, anthropologists and psychiatrists came to accept it as a pathology in its own right, linked to the victims belief in sorcery.

For a solution to be termed a scientific hypothesis, it has to be an idea that can be supported or refuted through carefully crafted experimentation or observation. Such arguments are typical of science, though are not restricted to it. So my jealousy explanation flunks the test for low prior probability. A comet with an orbit similar to the 1530 and 1606 comets did appear in December 1758. He decided to study the environmental impact of this herbicide on blue jay reproduction. 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.

Which of the following are characteristics of reliable empirical data? Which of the following has scientific investigation shown to be LEAST reliable in criminal prosecutions? 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. d. irreverent d. all of the above The term prior, in this case, means that the probability calculation must be done prior to your making any judgment about the explanation itself and prior to your making any observations pertinent to the observable outcome. Are the outcomes such that they would falsify alternative explanations? The physics of Descartes still dominated science, and it would be several decades before Newtons views completely won out. Sample exercise. He had a maritime tattoo, a military carriage, regulation side-whiskers, and an air of command.

Dear Papa Bear: Its just a wild guess, but I think somebodys been sleeping in your bed. (It is called double blind because neither those receiving the pills nor those administering the study knows which group is getting the real Vitamin C and which is getting the bogus Vitamin C.) By using large groups, the coincidence alternative is ruled out. When an explanations prior probability is extremely low, another alternative explanation is deception. General explanations are typical of science, though are not restricted to it. Unfortunately, there is no formula for calculating the prior probability of the observable outcome. Bring it all together by fully clarifying and evaluating the explanatory arguments in each of these passages. This result can be explained by the fact that because the teachers expected them to do well, their perceptions of each students ability rose and those childrens own self-image was enhanced. David Lewis and James Greene, Thinking Better.

The problem with his argument is that another explanation for these unnoticed images already exists; we all know that were capable of finding images if we look really hard for them, simply as the products of our imagination. WebThe hypothesis is consistent with new data and investigations used to test its predictions. Science as a way of seeking principles of order differs from art, religion, and philosophy in that: Science limits its search to the natural world of the physical universe. d. Frustration produces physical but not psychological aggression. A. Null hypothesis : this is known as the default hypothesis.It states that observation - question - hypotheses - predictions - results of investigation - conclusions Which are true of a hypothesis? c. athletes have higher moral development than nonathletes 2003-2023 Chegg Inc.

And if you had been wrongand you would have been wrongyou would have had the chance to correct the error of your ways. 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 arguer must have imagination to devise an explanation that is something more than a generalization of the experienced facts; and the evaluator must have imagination to think up viable alternative explanations for the sake of comparison.

An argument whose correct form, assuming that P is the explanation and Q is the observable outcome, is this: An explanation that can apply to a wide range of observable outcomes.
