The second scientific thinking is: correlation isn’t causation. Many psychology students make a common mistake during the interpretation of studies and they come up with a conclusion that when two things are compared with each other, one thing must cause the other. When one concludes that correlation means causation, he/she commits the correlation-causation fallacy. This is a fallacy because the claim that two variables are correlated does not mean that one is a cause for the other. It is good for us to note that a correlation between two things does not indicate a causal connection between them.
The third principle is: Falsifiability. One philosopher made an observation that for a claim to have meaning, it has to be falsifiable. However, some students fail to distinguish a falsifiable theory from a false theory. The principle of falsifiability does not state that a theory has to be false for it to be falsifiable. Nevertheless, the principle means that a meaningful theory could be proven wrong if certain types of evidence against the theory exist. A good scientific theory must predict predicts only certain outcomes, but not others. When evaluating a psychological claim, we ought to ask ourselves whether a certain principle can be disapproved or whether it is consistent with the available body of evidence.
The fourth scientific thinking principle is: Replicability. Replicability is the consistent duplication of the findings of certain studies. If the findings cannot be duplicated, the odds that the original findings were due to chance increase. Over the past years, psychologists have become aware of the importance of replication. Most replications aren’t exact duplications of the originals researcher’s methods. Discoveries have been made that the media are likely to report initial positive findings than ...Download file to see next pagesRead More

Scientific misconduct

...also implicit responsibilities, such as mentoring and controlling students' behavior and skills. As a part of the education program underlying a laboratory experience, there is teaching scientific behavior. The latter consists of not only making experiments following the scientific method but it also includes ethical behavior, since science is based on the assumption that experiments are true and reliable. Dr. Potter will likely have severe consequences from his lack of attention; for instance, he will need to publish a corrigendum or to retreat his paper from the journal. This act negatively affects one's credibility with negative fallout on future publications. c) Should the university...

Scientific Management

...shoved to its rational limit, with the resulting oppression of the workplace and devaluation of the labourer (Taksa 1992). Although the usefulness of scientific management in the 21st century has been largely criticised, some of its premises survive today in several major companies, such as McDonalds, Ford, and Toyota. This paper discusses the extent of the application of scientific management in the 21st century and how its limitations are turned into something productive. First, a presentation of an overview of Taylor’s scientific management is imperative. Frederick Taylor argued that actions rooted in traditional practice and established methods should be replaced by...

Science is a subject which requires learning for many years and inculcating the scientific temper amongst the children. In the era of Information Technology when the world is increasingly becoming technical, preparing the children for a better tomorrow becomes all the more crucial. Science teaching forms an important component of this teaching-learning process. Role of the teacher as well as the parents becomes quite crucial in developing the scientific temper in a child.

...On Concepts of Knowledge Different thinkers differently depict the term ‘knowledge’. The oldest idea came from Plato whose theory on knowledge is “justified true belief”. According to the theorists of Epistemology, belief is the most essential condition for gaining knowledge. If you have reasons for believing the truth you can gain knowledge. But if belief is not sustained by truth one cannot claim to know anything. For example, I may believe that the next prospective customer, whom I visit to make him buy my new insurance policy, will be more compliant than the last. But the person may turn out to be as disappointing as the previous one; in which case my...

The Scientific methods psychologists use

...Lecturer: The Scientific Methods Psychologists Use Natural observation Natural observation is a non-experimental analysis used bypsychologists, and it involves observing subjects in the real settings. The researcher inspects and documents the behavior of the matter in the real life settings. The method has varied advantages including providing first-hand information to the researcher, which is not biased, the researcher assess varied things without controlling the changes that occur, and it supports the external research validity. The method is also effective because it does not generalize the subjects when carrying out research study. However, it observes the findings...

...yielded true knowledge, and this knowledge ought to be retained. Bacon, however, was of the view that the antiquity disputations method of inquiry had led them astray in many instances, leading to superstitions and other alleged forms of knowledge that have no any basis, whatsoever, on the physical realities. Bacon argues that the ancients, or the people of the antiquity, were caught up in the “labyrinth of disputations”, which was not based on the material, sensible realities. For Francis Bacon, therefore, true scientific method should be based on the experience of the physical, material realities. And for this reason, Beacon dismissed...

...Recombinant DNA technology Recombinant DNA technology In obtaining the three plasmid DNA including A2-F, pFR-Luc, and Gal4, the study employed use of Luria broth and plasmid cloning techniques. Essentially, Luria broth defines a a bacteria culture media that with high nutrients used in laboratories. In addition, isolation of specific DNA sequences from complexes of varied sequences of DNA relates to DNA cloning (Walker and Rapley, 2009, p. 115). Plasmid or highly modified phage acts as vectors for replication of DNA fragment during cloning in a host cell. The inherent plasmid vector consists of three elements including cloning site, drug-resistance gene, and a replication origin (Stuttard and Rozee, 2013, p. 180). The latter... DNA technology ...

Knowledge and Scientific Methods

...Knowledge and Scientific Methods Principles of Scientific Thinking The principles of scientific thinking are one of the most important things that complement psychology and its study. It is also important to have their knowledge and consider them in everyday life since it is only these principles that will help in believing the things that people hear. The principles are helpful in decision- making especially in tough situations. (Lilienfeld, 2010). These principles include Ruling out hypotheses, Correlation versus Causation, Falsifiability, Replicability, Extraordinary claims, and Occam’s razor. Each principle explains and gives the understanding to different situations. Ruling out rival hypotheses This principle suggests... ...
