Alan Chalmers, a British-Australian philosopher of science and best-selling author, suggests a common view of science by which scientific knowledge is ‘reliable’ and ‘objectively proven’ knowledge that is derived from facts of experience, experimental procedure and observations. This essay aims to discuss the problems that are likely to be highlighted by a Popperian hypothetico-deductivist when confronted with Chalmers’ adverse views on the validity of the scientific method. Both Alan Chalmers and Karl Popper - renowned for the development of hypothetico-deductivist/falsificationist account of science - represent the two major, contradictory theories (falsification and induction) regarding the functionality of science. I will be structuring my argument around these two models and the several complications surrounding the inductivist’s account of science that are seemingly solved by Popper’s alternative.…
As one sociologist Popper argues that science is a open belief system where every scientist’s theory can be falsified, as science can be open to criticism and tested by others. For example if scientist argues water boils at 100 degrees Celsius this can be tested (falsified). However with religion this is impossible as you are unable to test religious ideas on what happens after death. This leads to religion not being falsified and science ruled by the theory of falsification. Thus leading to Popper to believe science has been successful in explaining and controlling the world becoming the main ideological influence in society today.…
According to Popper science is an open belief system where every scientist’s theories are open to scrutiny, criticised and tested by others. He says that science is governed by the principle of falsificationism. This is whereby scientists set out to try and falsify existing theories, deliberately seeking evidence that would disprove them. Such as the fact that the big bang is a theory that everyone accepts but there is much more that scientists do not know and more needed to be found therefore it could be false. It argues that there always can be more and more evidence for every theory that has ever been made and proven. Then when disproving these knowledge claims allows scientific world to grow. It is cumulative, whereby it builds on achievements of previous scientists. This explanation shows that science can be a belief system as nothing can ever be proven 100% as there will always be something or someone that will disprove a theory with other evidence and therefore people belief what they have been told. This is much like religion in a way by the fact that religion cannot be proven it is something that people belief in.…
Karl Popper advocates, as a more efficient way to examine a scientific hypothesis, which of the following?…
Karl Popper argued that induction cannot be used in science. He says that induction can never be proven by experimentation. Science instead uses deduction by formulating theories and hypotheses. Science uses the method of conjecture and refutation. Hypotheses can never be proven or verified, but their success can be compared to other hypotheses. The usefulness of a hypothesis can be determined through deduction or predictions. Scientists test theories by making completely falsifiable claims. If there is nothing you can to do disprove the claim then the hypothesis is corroborated. A corroborated theory should not be considered true, merely accepted until better theories are discovered. Popper said that a theory can never be confirmed by observation. Where Hume argues that our theory originates from repetition, Popper argues that theory begins before repetition. Therefore, Popper argued that science does not even use induction.…
In Adler’s definitions, he offers his own adaptation of Science, Knowledge, Reality and Appearance. Approaching his definition of science, he explains how the meaning has changed over thousands of years and is now more empirically based. Since the word science can be used in areas other than the experimental side such as mathematics, history, and philosophy, he looks at it from a perspective that “There is no science of science”. He’s trying to say that science is the whole domain of widely accepted knowledge and that we need both science and philosophy to understand what we think we know.…
People often regard the ideas that are generally accepted by the multitudes as “truths”. However, many of them are not scientifically proven and lack logical and reasonable explanations. According to Saupe’s “What is Pseudoscience?”, such ideas are called “pseudoscience”. To be more specific, they are claimed to be scientific, but do not have objective evidence to prove that they are true. If people cannot distinguish between pseudoscience and scientifically proved science, the results would be consequential. False science would lead to the misunderstanding of things and cause people to do things wrongly and might lead to harms and damages eventually. To evaluate if the information is credible, there are some standards; for example, check the credentials of the author, check the credibility of the sources of the information and the relevant sources that the information contains and see if the author has good logics to prove the information (Saupe, 2005).…
Karl Popper in his book The Logic of Scientific Discovery developed a theory of falsificationism as a guide to how science should be conducted, and as a demarcation principle to differentiate between science and pseudoscience. This principle I hold, though useful, is not definitive, and does not serve as an adequate guide to scientific practice. This essay will present the case to defend this thesis, first by clearly explicating falsificationism and showing what ways it is useful, presenting two arguments against the theory and responding to an objection. This will show why Popper’s falsificationism is useful but not a definitive guide to scientific practice.…
Science the word itself is dominant around the world as almost all the theories and concepts in many subject areas are based on facts which are scientifically evident based. Psychology on the other hand presented as science in oxford dictionary definition. Reber (as cited in Henriques 2004) says that psychology cannot be defined but it is created by scientist to understand the human mind and behaviour. According to Henrique (2004) it is justifiable to define Psychology as science of human behaviour. He further confirms his statement by presenting Cognitive Behavioural Therapy and how it consumes findings in the cognitive and behavioural science to develop new psychosocial interventions that were empirically supported…
Pseudoscience refers to research that appears to be science but that lacks some of the underlying key aspects. Often, these include components such as submitting publications for peer review, performing research studies to gather results, and repeating these studies to find similar results. The problem of separating science from pseudoscience generally a difficult one because of the difficulty of defining science. Most scientists would agree that in order for a hypothesis to be scientific, it must be refutable. A theory or hypothesis which cannot be refuted is not science3.…
Kuhn believed that history is indeed very important in understanding science. He claimed that in order to understand science, one has to look into the history of science. He also had a theory, which was written in the book of Structure of Scientific Revolutions, called the Paradigm Shift. Paradigm is a sum of accepted metaphysical assumptions, theories, methodologies, manuals and techniques. In Kuhn’s theory there are three periods of science, which are Normal science, Crisis and Scientific Revolution. Normal science is the continuation of pre-scientific era that formed many opinions, but had no consensus or general agreement about how one should do to gather information regarding a phenomenon, and no generally accepted background information. After a general agreement on how a phenomenon is reached, then the Normal science period begin. In this period, scientists will try to solve the paradigm that was not finished or had minor problems. When the scientists can’t deal with too many anomalies, the situation goes into Crisis period. To solve the crisis, people could either…
Although Popper was not a logical positivist, he did communicate and disagree with them. Popper’s initial goal was to ‘understand science;’ he began to develop a system with which to distinguish science from ‘non-science’ or ‘pseudo-science’. Popper coined this obstacle ‘the problem of demarcation. He attempted to deal with this problem by proposing a solution which he entitled ‘falsificationism,’ which claimed that ‘a hypothesis is scientific if and only if it has the potential to be refuted by some possible observation.’ Popper’s whole conception of how science should be understood and practiced was centered around the belief that when investigating a scientific theory, we should never increase our confidence in the truth of a theory as it has simply not yet been proven wrong. Popper maintained that we should never assume one theory to be closer to the truth than another as it is impossible to ever prove a theory, and in this sense we should approach scientific theories tentatively. Upon this framework of understanding, Popper attempted to build a practical way of pursuing science. He proposed a system of perceiving scientific change that involved a simple two-step cycle: First, conjecture, the proposition of new theories; the best of which are bold and striking. Secondly, attempted refutation which if succeeds draws us back to conjecture. Popper believed that this was a practical and physical way of dealing with science which should naturally evolve and push us towards developing new…
In general, it is not possible to agree with both Carnap and Popper on the question of demarcation of scientific science statements and unscientific statements.…
The boundary between science and pseudo science, better known as the demarcation issue has been in debate for decades between philosophers of science in order to find the basis on which this separation can exist. The likes of Karl Popper initially introduced the demarcation criterion called “falsificationism” which states that falsifiability is the “logical possibility that an assertion can be shown false by an observation or a physical experiment”[1] and it was on this beginning that Popper was able to make the distinctive separation of science from pseudoscience. However if Popper’s approach was taken into consideration, many scientific discoveries would have been impoverished, since the theory behind the discovery would have been deemed…
A scientist would initially observe and classify data. He would proceed to look for pattern in the data and formulate a hypothesis. Following this, the scientist would make a predication. The scientist would test this predictions through experiments. If the experimental results confirm the hypothesis, a scientific law has been discovered. The scientific method limits the influence of bias and prejudice in the experimenter. It provides an objective, standardized approach to conducting an experiment and, in doing…
