Reject explanatory arguments that have unfalsifiable explanations; they are in principle unable to satisfy the first part of the total evidence condition. Another good way to check for an improbable outcome is to ask this: Does another explanation for this outcome already exist? To illustrate how this strategy is related to the prior epistemic probability of the outcome, suppose I propose the following fanciful explanation: I am bewitched, so that gravity has no affect on me whatsoever; the only reason I am able to walk around on the ground is because of magical shoes that counteract the bewitchment when I wear them.

An increase in family income leads to an increase in the percentage of income spent on housing. Never have. So an argument of this sort is probably just a logical mistake, not an explanatory argument. The deception explanation should often be considered, but it is subject to the same high standards that apply to any other explanatory argument. b. c. when participants perceive they are the recipients of poor officiating 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. Which aspect of the scientific method occurs first? Again, the two sorts are subject to the same logical standards, though we can shape our inquiry a bit differently in each case. How does Abbys conclusion fare in the face of this alternative explanation? This interlocks with the test, under the preceding improbable-outcome criterion, of asking whether an explanation for the outcome already exists.

Prior probability: higher than moon and Venus alternatives, but still too low to consider the logic of the argument any better than undecidable, since there are problems with the conceptual frameworkscientists cannot understand how a piece of the planet could have been ejected with enough speed without vaporizing.. The null hypothesis was a better fit to your data. Which of the following describes this pill? 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). A second way of distinguishing among explanatory arguments is in their level of generality. Vague outcomes are likely to have a high prior probability and thus are likely to signal that the argument is logically weak.

Newtons theories, for example, while applied here to Halleys comet, actually cover the motion of all objects at all times. In many cases, an explanation is formulated before the observable outcome has been observed. Epistemic probability, as explained in Chapter 9, refers to the probability of the statements truth given all relevant available evidence. a. 1. If there is good reason to expect it anyway, then the explanation is doing no work and receives no logical support. Then state whether it is general or singular and whether the explanation or the observable outcome came first. You'll get a detailed solution from a subject matter expert that helps you learn core concepts. 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. A pathway by which we can come to discover and better understand our world.

WebA hypothesis (plural hypotheses) is a proposed explanation for a phenomenon. Both explanations do an equally good job of entailing Periers results as their observable outcome. Step 5. This point is not lost on investment companies. 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. . Aha! you say, Someone is casing the joint and now knows not to burglarize us, since someone answered the phone!

The requirement that it be possible to specify some observable outcome of an explanation that could prove it to be false. The lights in this old house keep flickering. 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! There are two types of hypothesis. - Tend to be broad. One good way to check for simplicitya way typically more useful with singular than with general explanationsis to ask whether the explanation offers only as many explanatory entities as needed. the operation of the whole mind rather than the individual parts.
