New evidence shows that optimists live longer. Organisms are able to maintain relatively constant internal conditions that may differ from the external environment. Second part: Reasonably high prior probability for the explanation; the causal mechanismnatural selectionis fairly well understood, and no alternate seems more likely. d. all of the above C. It's correlated, but not causal. Explanation: the meteorite came from Mars. For each of the brief explanatory arguments, identify the explanation and offer a more precise observable outcome that would lower its prior probability and thus make the argument logically stronger. WebWhich of the following is an explanatory hypothesis? The Total Evidence Condition for Explanatory Arguments. The point is not that the world is necessarily simple, any more than the world is necessarily filled only with frequently occurring or nonmysterious things. Two Alternative Explanations to Bear in Mind. If-clause is intended to provide better understanding of then-clause. More subtle examples are easy to find. c. psychologically harming another individual And so I do. When you cannot think of another explanation, it can be tempting to accept an explanatory argument even when the prior probability of the explanation is exceedingly low. A useful scientific hypothesis is one that is: A hypothesis that states that there is a lack of relationship between two factors is called: When conducting a scientific experiment, which of the following is tested? (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. But this explanation has an exceedingly low prior probability. The first part of the total evidence condition is that the observable outcome must have a low prior epistemic probability. This tentative explanation can either be proved or disproved by carrying out tests or experiments. a. immature H. Huxley, letter, September 23, 1860. It is not likely that we would now call it Halleys sun. This closure did not occur during a normal period. It must establish an alternative explanation for a phenomenon.

For general explanations, a good way to check for simplicity is to ask. This is an important source of the comet arguments logical strength. a. instinct theory Real estate investment trusts (REITs) experienced a record level of profitability in 2004 Soles Newtons theories, for example, while applied here to Halleys comet, actually cover the motion of all objects at all times. This is why, for example, we are amused but not persuaded by the rooster who thinks that the sun is raised each morning by his mighty crowing. Just as a good explanatory argument rules out coincidence, it also rules out deception. This hypothesis is not necessarily the right explanation. Null hypothesis : this is known as the default hypothesis.It states that Suppose the prior probability that the butler did it was .10, likewise for the chambermaid. Would it require the world to function in mysterious ways or in ways that differ dramatically from the ways that are well established by science? Add a moving part to the machine, and the probability that every part will work drops dramatically. The plumber explanation is burdened with improbabilities: The answer in each case is very infrequently. Populations have the capacity to change over time. 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. b. Second, its explicit premisethis water boiled quicklyis the observable outcome of the explanation.

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. The correct form for an explanatory argument, assuming that P is the explanation and Q is the observable outcome, is this: The first premise, often implicit, states that the explanation enables you to predict the observable outcomethat it really is an outcome. When I bought the housedespite its terrible conditionthe sellers let slip that someone had died here. 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. instrumental-reactive aggression theory, According to more recent research by Anderson and Bushman, aggression ranging from instrumental to reactive should be viewed b. bracketed According to the given data. Youll seethe audience will applaud at the end. A team of researchers recently found no differences that would account for the beak variations. Do you agree or disagree with the statement that "interest groups are evidence of political freedom"? WebA hypothesis is a potential answer to the question, one that can somehow be tested. 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! He argued that, by super-cooling the stomach, acid production was reduced and the ulcer relieved. Lack noticed that on an island shared by two species of finches, ones beak was markedly smaller than the others. 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.

A statement that enables us both to predict and to better understand the cause of that which it explains. sentence with an appropriate personal pronoun. You note a fuzzy growth on some of the gels in your incubator. Note that I am being careful not to say that coincidence is thus proven to be the correct explanation; the point, a more modest one, is that skill is not supported as the correct explanation. Look for coincidence as an alternative explanation. Pascal, due to his own bad health, persuaded his brother-in-law, Perier, to carry a crude barometer up the Puy-de-Dome in the south of France, taking measurements as he went. Ask whether an explanation for the outcome already exists. As with our other inductive arguments, the total evidence condition for logical success has two parts. A frequently observed and poorly understood phenomenon in which there is a positive response to treatment with an inactive substance. B. Women are built for giving birth, and the long haul that involves. , Scientists at the University of Manchester have discovered a distant planet where virtually no one would have expected it to be, orbiting a pulsar star, PSR1829, which was born during a supernova. Clearly, the plumber explanation has a much lower prior probability than does the affair explanation. If hes her father, then he will go to great lengths to take care of her. As we have seen, explanations that make good sense are those for which we have an adequate conceptual frameworkfor which we have a reasonably good account of the causal mechanisms involved. b. fans become more aggressive after watching violent contact sports I thought it was the wind blowing up the canyon, like it does, you know, except it was real still. I subconsciously wanted the test to succeed, so I tended not to count less severe colds that I otherwise would have counted.
