Philosopher Karl Popper is widely known for his rejection of classical inductivism, the idea that scientific knowledge is derived only from observation, and also his support of empirical falsification, the idea that scientific theories cannot be proven correct, but they can be proven false. In other words, empirical falsification means that theories can and should be closely and thoroughly examined by decisive experiments. In Popper’s view, a claim must be falsifiable, or testable, in order for it to be scientifically true; if a hypothesis cannot be refuted, then it is not a scientific claim. Untestable ideas and theories within science are dubbed “pseudo-science” by Popper, because they have no falsification. Things like Anthropology and …show more content…
Alternatively, the proclamation “the Earth is flat” is scientific because it can be proven to be false through scientific investigation. Popper came up with the term “Critical Rationalist”, an expression to describe his ideology. Critical rationalists believe that hypothesis and theories should be criticized in a rational way and should be tested in a way that they can be proven to be false.
Popper was inspired to come up with his idea of falsification because of the many advances happening in the Western scientific world while he was growing up in the early 1900’s. Growing up in this time, Popper was intrigued by the psychoanalytic theories of Sigmund Freud and even attended lectures of Albert Einstein about the rules of the universe. He noticed that these distinguished thinkers used different methods within their work. Freud could make almost any piece of data work in favor of his theory. To illustrate, he could explain someone’s intimacy issues both in terms of not being hugged enough as a child or in terms of being hugged too much. Evidence to support his claims were all around. Contrary to Freud, Popper noticed that Einstein was making a different kind of prediction. Instead of looking in the past to “predict” the present like Freud, he was looking ahead to predict things in the future. Popper saw Einstein’s method to be extremely risky because if the

Joel Achenbach, the author of the article, “Why Do Reasonable People Doubt Science?” starts of by saying that in today's era the people often disagree with scientific reasoning. The world we live in today is so full of problems it's hard to tell what is real anymore. The decision is left to the individual to decide what to believe is true or false, and then how there going to put their beliefs into action. Achenbach later explains in his article that the scientific method pushes back all the opinions and unfolds the real truth.
The development of the scientific method in the late 1500’s to the early 1600’s was a crucial stepping-stone in the science community. The scientific method is based upon observations, hypotheses and experimentation. The concept is rather simple, and can be applied to many areas of study. Once an observation is made, the observer can make a hypothesis as to why that phenomenon occurs and can then design an experiment to prove whether or not that hypotheses is valid. Although the scientific method has been extremely useful in the discovery of various things from usages of medications to studying animal behavior, there are still those who question the usage of this tool. These critics claim that since
Pseudoscience is a claim or belief that does not conform to the scientific method. Generally, pseudoscience will have a lack of scientific evidence and will seem almost as an exaggeration. The evidence that is there to support it is not heavily supported or seems to be conforming to fit the “hypothesis”. In the article I found, James Cameron dove by himself to the deepest part of
In recent news, a new community has outwardly spoken on the theory, the earth is flat. This community calls themselves “The Flat Earth Society” or “Flat Earthers”. This began around the mid-20th century and has rapidly grown with the expansion of social media, and influencers such as rapper B.o.B and basketball player Shaquille O’Neal.
This idea backed up with firm evidence went strictly against previous data and evidence that alluded to the contrary, which pointed to the Lunarians could never have existed on Earth. Several quotes from Hogan throughout the novel can analyzed and recognized as philosophical, such as “The trail behind this rapid succession of new developments was … littered with the abandoned carcasses of dead ideas,” (Hogan, pg 133) and “Lights burned through the night at Houston … as the same inevitable chains of reasoning were reeled out again and yet again, the same arrays of facts scrutinized for new possibilities or interpretations.” (Hogan, pg 149). The quotes shown above parallel with Popper’s idea of critical pluralism, and how people hold on and believe in one solid truth until it is shattered and replaced with a more substantiated truth. In particular of this novel, it is difficult for the scientists to agree with one universal truth since both pieces of evidence are seemingly irrefutable and crash into each
Every genuine test of a scientific theory, then, is logically an attempt to refute or to falsify it, and one genuine counter-instance falsifies the whole theory. In…theory of demarcation is based upon … perception of the logical asymmetry which holds between verification and falsification: it is logically impossible to conclusively verify a universal proposition by reference to experience …, but a single counter-instance conclusively falsifies the corresponding universal law. In a word, an exception, far from ‘proving’ a rule, conclusively refutes it (Thornton,
What is Science? When it comes to the word ‘science’ most of the people have some kind of knowledge about science or when they think of it there is some kind of image related to it, a theory, scientific words or scientific research (Beyond Conservation, n.d.). Many different sorts of ideas float into an individual’s mind. Every individual has a different perception about science and how he/she perceives it. It illustrates that each person can identify science in some form. It indicates that the ‘science’ plays a vital role in our everyday lives (Lederman & Tobin, 2002). It seems that everyone can identify science but cannot differentiate it correctly from pseudo-science and non-science (Park, 1986). This essay will address the difference between science, non-science and pseudo-science. Then it will discuss possible responses to the question that what should we do when there is a clash between scientific explanation and non-scientific explanation. Then it will present a brief examination about the correct non-scientific explanation.
The following essay aims to discuss the inconsistencies between the inductivist and Popper’s points of view of science rationality of science in light of claims that the scientific method is inductive yet an inductive method is no. I think is rational to say that inductivist view of science has significant contradiction that Popper’s view solves. To support Popper’s view my argument will introduce the inductivist and falsificationsist views and I will focus in showing the issues of considered science as objective, scientific knowledge as proven and nature as uniform as well as the differences between inductivism and falsificationism to the creation of hypothesis.
Unlike inductivists, falsificationists believe that there is no way to conclusively prove that a theory is true. Consequently, they will resist stating that they’ve proved a theory to be true. Instead, falsificationists will consider a theory to be true so long as it has not been proven to be false. Unlike the strict five-step process held by the inductivist account of science, falsificationists hold that scientific progress comes about “by trial and error, by conjectures and refutations” (Chalmers 60). In the falsificationist picture, theory change happens constantly, and this process is what constitutes scientific progress. “It can never be said of a theory that it is true, however well it has withstood rigorous tests, but it can hopefully be said that a current theory is superior to its predecessors in the sense that it is able to withstand tests that falsified those predecessors” (Chalmers
In this essay I attempt to answer the following two questions: What is Karl Popper’s view of science? Do I feel that Thomas Kuhn makes important points against it? The two articles that I make reference to are "Science: Conjectures and Refutations" by Karl Popper and "Logic of Discovery or Psychology of Research?" by Thomas Kuhn.
Karl Popper is commonly regarded as one of the greatest philosophers of science in the 20th Century. He is well known for his rejection of the inductivist viewpoint of the scientific method, in which one uses observation to propose a law to generalize an observed pattern, and later confirm that law through more observation. Popper states that “induction cannot be logically justified” (Popper 14). Inductivism relies on the process of inductive reasoning which is a logical process in which multiple premises, all thought to be true and found to be true most of the time, are combined to obtain a conclusion and in many cases formulate a law or theory. Popper rejected the inductivist viewpoint in favor of a theory called empirical falsification which holds that a theory can never be proven, but it can be falsified, and therefore it can and needs to be scrutinized through experimentation.
Popper and Kuhn held differing views on the nature of scientific progress. As seen in Popper’s falsification theory, he held that theories can never be proved only disproved or falsified. Once a theory is proved false we move on to the next. Kuhn, on the other, hand argued a new paradigm may solve puzzles better than the old one but you cannot describe the old science as false. Both seem to share the Kantian idea that the really real, independently existing world is completely unknowable. Kuhn further asserts that the empirical world, which is knowable, is partly constructed by our categories and concepts. The fundamental difference in their views are best stated in Kuhn’s own words, “A very different approach to this whole network of problems has been developed by Karl R. Popper who denies the existence of any verification procedures at all. Instead he emphasizes the importance of falsification, i.e., of the test that, because its outcome is negative, necessitates the rejection of an established theory. Clearly, the role thus attributed to falsification is much like the one this essay assigns to anomalous experiences, i.e., to experiences that, by evoking crisis, prepare the way for a new theory. Nevertheless, anomalous experiences may not be identified with falsifying ones.”(Kuhn, 145) As seen by this passage, the fundamental difference between Popper and Kuhn is that Popper disregards “verification” and Kuhn asserts that “falsification” only takes place once a
Science is flawed because people are flawed. Therefore our definition of science, along with its qualities for which we identify science with, is rational. However, the way we do science exhibits traces of irrationality.
Assumptions in the title of this essay imply that results, theories and laws resulting from the current system of peer review multiple perspectives produce completely infallible objective truth, this is a false premise. Whilst the group of knowers known as the scientific community have collectively less bias than one lone knower trying to understand the universe, there is still collective and engrained level of institutional bias. The same problems of confirmation bias and expectation are present in a group of knowers just as they are with one single knower. According to Karl Popper (1902-1994) the best way to eliminate any expectation and confirmation bias was to falsify and disprove rather than confirm one’s hypothesis and predictions. Popper argues: no matter how convincing an argument or theory is, all that is needed to disprove it is one piece of valid counterclaiming evidence. Whilst this theory is valid on an individual level, it really becomes an effective tool in the objectivity of science on a large scale. Despite this attempt at objectifying and ‘protecting against’ error and bias it is inadequate due to inherent flaws in the scientific method. Induction, moving from the specific to the general, is the key element in scientific logic. Any theory or law ‘proved’ through this logic has some key flaws: the main flaw being that inductive logic can never be certain of any event happening or of any prediction. Richard van de Lagemaat
