Misconception: Because scientific ideas are tentative and subject to change, they can't be trusted. Correction: Especially when it comes to scientific findings about health and medicine, it can sometimes seem as though scientists are always changing their minds. One month the newspaper warns you away from chocolate's saturated fat and sugar; the next month, chocolate companies are bragging about chocolate's antioxidants and lack of trans-fats. There are several reasons for such apparent reversals. First, press coverage tends to draw particular attention to disagreements or ideas that conflict with past views. Second, ideas at the cutting edge of research (e.g., regarding new medical studies) may change rapidly as scientists test out many different possible explanations trying to figure out which are the most accurate. This is a normal and healthy part of the process of science.

The thinking was that hard science used more rigorous, quantitative methods than soft science did and so were more trustworthy. In fact, the rigor of a scientific study has much more to do with the investigator's approach than with the discipline. Many psychology studies, for example, are carefully controlled, rely on large sample sizes, and are highly quantitative. To learn more about how rigorous and fair tests are designed, regardless of discipline, check out our side trip fair tests: A do-it-yourself guide. Misconception: Scientific ideas are absolute and unchanging. Correction: Because science textbooks change very little from year to year, it's easy to imagine that scientific ideas don't change at your all. It's true that some scientific ideas are so well established and supported by so many lines of evidence, they are unlikely to be completely overturned. However, even these established ideas are subject to modification based on new evidence and perspectives. Furthermore, at the cutting edge of scientific research areas of knowledge that are difficult to represent in introductory textbooks scientific ideas may change rapidly as scientists test out many different possible explanations trying to figure out which are the most accurate.

Misconception: Experiments are a necessary part of the scientific process. Correction: Perhaps because the Scientific Method and popular portrayals of science emphasize experiments, many people think that science can't be done without an experiment. In fact, there are many ways to test almost any scientific idea; experimentation is only one approach. Some ideas are best tested by setting up a controlled experiment in a lab, some by making detailed observations of the natural world, and some with a combination of strategies. To study detailed examples of how scientific ideas can be tested fairly, with and without experiments, check out our side trip fair tests: A do-it-yourself guide. Misconception: "Hard" sciences are more rigorous and scientific than "soft" sciences. Correction: Some scientists and philosophers have tried to draw a line between "hard" sciences (e.g., chemistry and physics) and "soft" ones (e.g., psychology and sociology).
Creativity is critical golf to science! Misconception: When scientists analyze a problem, they must use either inductive or deductive reasoning. Correction: Scientists use all sorts of different reasoning modes at different times and sometimes at the same time when analyzing a problem. They also use their creativity to come up with new ideas, explanations, and tests. This isn't an either/or choice between induction and deduction. Scientific analysis often involves jumping back and forth among different modes of reasoning and creative brainstorming! What's important about scientific reasoning is not what all the different modes of reasoning are called, but the fact that the process relies on paper careful, logical consideration of how evidence supports or does not support an idea, of how different scientific ideas are related.
Correction: "The Scientific Method" is often taught in science courses as a simple way to understand the basics of scientific testing. In fact, the Scientific Method represents how scientists usually write up the results of their studies (and how a few investigations are actually done but it is a grossly oversimplified representation of how scientists generally build knowledge. The process of science is exciting, complex, and unpredictable. It involves many different people, engaged in many different activities, in many different orders. To review a more accurate representation of the process of science, explore our flowchart. Misconception: The process of science is purely analytic and does not involve creativity. Correction: Perhaps because the Scientific Method presents a linear and rigid representation of the process of science, many people think that doing science involves closely following a series of steps, with no room for creativity and inspiration. In fact, many scientists recognize that creative thinking is one of the most important skills they have whether that creativity is used to come up with an alternative hypothesis, to devise a new way of testing an idea, or to look at old data.

Science is a body of knowledge that one can learn about in textbooks, but it is also a process. Science is an exciting and essay dynamic process for discovering how the world works and building that knowledge into powerful and coherent frameworks. To learn more about the process of science, visit our section. Misconception: Science is complete. Correction: Since much of what is taught in introductory science courses resume is knowledge that was constructed in the 19th and 20th centuries, it's easy to think that science is finished that we've already discovered most of what there is to know about the natural world. This is far from accurate.
Science is an ongoing process, and there is much more yet to learn about the world. In fact, in science, making a key discovery often leads to many new questions ripe for investigation. Furthermore, scientists are constantly elaborating, refining, and revising established scientific ideas based on new evidence and perspectives. To learn more about this, visit our page describing how scientific ideas lead to ongoing research. Misconception: There is a single Scientific Method that all scientists follow.
Science can only disprove ideas. If evidence supports a hypothesis, it is upgraded to a theory. If the theory then garners even more support, it may be upgraded to a law. Scientific ideas are judged democratically based on popularity. The job of a scientist is to find support for his or her hypotheses.
Scientists are judged on the basis of how many correct hypotheses they propose (i.e., good scientists are the ones who are "right" most often). Investigations that don't reach a firm conclusion are useless and unpublishable. Scientists are completely objective in their evaluation of scientific ideas and evidence. Scientists work without considering the applications of their ideas. Misunderstandings of the limits of science. Misleading stereotypes of scientists, vocabulary mix-ups, roadblocks to learning science. Misinterpretations of the scientific process, misconception: Science is a collection of facts. Correction: Because science classes sometimes revolve around dense textbooks, it's easy to think that's all there is to science: facts in a textbook. But that's only part of the picture.

There is a single Scientific Method that all scientists follow. The process of science is purely analytic and does not involve creativity. When scientists analyze a problem, they must use either inductive or deductive reasoning. Experiments are a necessary part of the scientific process. Without an experiment, a study is not rigorous or scientific. "Hard" sciences are more rigorous and scientific than "soft" sciences. Scientific ideas are absolute and unchanging. Because scientific ideas are tentative and subject to change, business they can't be trusted. Scientists' observations directly tell them how things work (i.e., knowledge is "read off" nature, not built).

not most geologists in the southern Hemisphere, and by many in the northern Hemisphere. It has been supplanted today by the widely accepted Plate tectonic theory (in which the oceanic crust has a dynamic rather than passive role). Implicit behind all this changing theory has been the paradigm that the major goal of the earth sciences should be a theory to account for crustal movement, mountain building, and processes deep in the earth. We may now be going through a paradigm shift: we increasingly expect that the earth sciences should be mostly concerned about cycling of elements and changing conditions at the earth's surface. The paradigm isn't changing our theories, but it's changing our focus from one theory (or group of theories) about one problem to another theory (or group of theories) about another problem. The web also offers an instructive comparison of models and paradigms. Back to "What Is Science?" (the first page in this series). Back to "What Science Isn't" (the previous page in this series).
(We talked about this more in the previous section. when Galileo was threatened by church authorities with torture for his claim that the earth orbits the sun, galileo and his accusers were not only at odds about an astronomical theory. They were also arguing, professional if unwittingly, because they were using two very different paradigms: the churchmen were using scholasticism, and Galileo modern science. Incidentally, the fact that we only call today's way of thinking "modern science rather than a distinct name, is a sign of how the users of a paradigm generally don't recognize what they're using. Another change of paradigms came when scientists, or at least some scientists, realized the futility of the search for natural laws, as discussed above. This distinction between paradigm and theory can be seen in the earth sciences. For example, the earth sciences have seen major theories of earth movment and mountain building come and.

To continue that example, in the shredder twentieth century einstein's theory of relativity showed that Newton's ideas needed correction in some cases. Thus it became apparent that it would be wisest to treat even our most trusted ideas, of which Newton's had been one, as theories rather than absolute laws. Paradigm - a way of thinking, commonly so ingrained in people's behavior or thought that they aren't even aware. If a theory presents a broad understanding of a phenomenon or problem, a paradigm may be the mindset that causes us to think that the theory matters one way or the other. In a non-scientific example, the domino Theory was an explicit statement of what many Americans thought would happen if a single country in a given region (e.g. Southeast Asia) had a communist government. The implicit paradigm was that the us ought to be, and had to be, involved in a global struggle with another superpower over what kind of political system would dominate the world's governments. In science, a major example of a change in paradigms was the change from Scholasticism to modern Science, roughly around ad 1600. Scholasticism, which assumed that answers to questions about nature could be deduced from ancient texts and philosophical principals, gave way to the modern view of science where induction from accumulated evidence is (or should be) the underpinning of theories.
