According to Holman, Lanfear, Head, and Jennions (2015) “scientific progress rests on reliable data, yet data collection is often subjective. Subjectivity can create biases, many of which derive from cognitive and sensory biases common to us all” (p. 1). They agree with Nickerson (1998) that “confirmation bias ensures that we preferentially detect, focus on, and recall outcomes that confirm our beliefs” (Holman, Lanfear, Head, and Jennions, 2015, p. 1). Due to this, when scientists research a subject they interpret the results through the eyes of their opinions. Holman et al (2015) asserts that this bias affects not just the data collection, but the study as a whole (p. 1). For example, in the case of medication testing, an experimenter may …show more content…
189). He states that understanding confirmation bias is vital, since “it can have significant consequences in many nonlaboratory contexts” (Nickerson, 1998, p. 190). There are numerous situations in which confirmation bias can be born from, two of the deadliest are fear and hope. An example of confirmation bias born from hope can be found when looking at those who are extremely ill. These individuals hope for a mystical cure and when they research a professed miracle treatment, they only take in the information that proves it to be true. In these instances, both fear and hope motivate confirmation bias, they fear death and hope for life. The witch hunts in the 15th, 16th, and 17th centuries act as an example for confirmation biases created by fear (Nickerson, 1998, p. 191). During those times, tens of thousands of people were killed because others believed them to be practicing witchcraft (Nickerson, 1998, p. 191). Due to this false belief, people would see certain acts and claim that they were evidence that witchcraft was occurring. They would also disregard any evidence proving the contrary. These two examples are of confirmation bias born from strong emotions, each of which can have devastating results if left …show more content…
He is in agreement with Tuchman (1984) that “’once a policy has been adopted and implemented, all subsequent activity becomes an effort to justify it’” (p. 191). They state that this is a form of confirmation bias. Policy makers only look at cases in which the policy is or could be a success, and they ignore instances where it falls short. Confirmation bias can also have an effect on medicine. Nickerson (1998) quotes Boorstin (1985) in saying: “For 1500 years the main source of European physicians’ knowledge about the human body was not the body itself … [but] the works of an ancient Greek physician [Galen]. ‘Knowledge’ was the barrier to knowledge. The classic source became a revered obstacle” (p. 192). This illustrates that the acquisition of some amount of information does not mean that the pursuit of knowledge should be halted, instead, it should be continued. These physicians only paid attention to the instances when patients were healed after a specific treatment, allowing them to continue to believe their knowledge of physiology was enough (Nickerson, 1998, p. 192). Medical practitioners ignored evidence that proved that they needed to further understand the human body due to the fact that they were comfortable in the knowledge passed down from Galen. Confirmation bias halted to exploration of the human body and the advancement of medicine for nearly two thousand
There has been an ongoing debate on whether psychology is indeed scientific, although recent, psychology is now considered a science. This is because it uses scientific methodology in researching, devising treatments and measuring the outcomes. These methods include collecting and analysing data and concluding their findings in order to identify whether the research or treatment adequality solves the problem. Scientific studies must be replicable, this means the if repeated exactly the same, the results should produce an identical outcome. Replicability can be increased by ruling out any alternatives that may not have originally been thought of. Objectivity in science is the idea that scientist, in an attempt to get the best results, must first
As described by Dr. Atul Gawande in his book Complications, medicine “is an imperfect science, an enterprise of constantly changing knowledge… fallible individuals” making medicine different from other scientific fields
This essay assesses the claim that witch-hunting was rarely an uncontrollable or hysterical phenomenon. Witch hunts have traditionally been presented in the academic literature as the result of a panicked reaction to supposed malevolent devil worship (e.g., Trevor-Roper 1969; Thomas 1972). In support of this interpretation, it is possible to cite numerous cases in which large numbers of people were put on trial, imprisoned, tortured, and executed seemingly without reason and on poor evidence. It is sometimes argued that a number of the more famous trials were uncontrollable and hysterical in the way they were conducted. Examples include the North Berwick witch trials (1581-1593) in Scotland, the Salem witch trials in America (1692-1693), the Torsåker witch trials in Sweden (1675), and the Trier (1581-1593), Fulda (1603-1606), Bamberg (1626-1631), Würzburg (1626-1631) witch trials in Germany, among others (Briggs 2002; Ankarloo and Henningsen 1999). This argument has also been based on the development of a fierce culture of anti-witchcraft beginning in the 14th century, as evidenced by the publication of books on demonology and the emergence of professions such as ‘witch-hunters’ and ‘inquisitors’ (Ankarloo and Henningsen 1999). This essay argues that these select cases were the exceptions to the rule and that the incidence of ‘witch hysteria’ was relatively low. Contemporary perceptions of witchcraft have been misrepresented by focusing too narrowly on the most dramatic
Due to many people who had begun to think in a more scientific way, this meant that they were more open into accepting Jenner’s theory for Vaccinations. This implies that if people’s attitudes were similar to people who had supernatural beliefs, they would not have accepted the theory, therefore without the changing attitudes, Jenner’s work would not have caused a huge medical progression.
Beginning in 1692 in the small farming community of Salem Village, Massachusetts Bay Colony, young girls fell ill and initiated odd behavior. Physicians determining the cause of the outbursts deemed impossible, leaving one option remaining: witchcraft. Now, with the supernatural rumors spreading throughout the minuscule Puritan community, commenced a mass hysteria. Neighbors accused neighbors, daughters accused mothers, even a dog was tried and killed. A year later, the paranoia and fear settled, but not after the death of at least twenty people. One might wonder, how does a simple, small town gain such fear in the unproven accusations of others?
Confirmation bias is a primary issue that prevents people from perceiving the world objectively. The phenomenon occurs when an individual chooses to expose themselves only to media and information that confirms a personally held belief rather than consider another side of the argument. In the media age we are currently in, it is remarkably uncomplicated to find countless arguments on one side of a controversial debate to buttress one’s own existing beliefs; we come to believe in a false consensus of our beliefs due to our limited exposure to other opinions. Consequently, especially in the United States due to having gone through an incredibly sensationalized presidential election, we are in a time somewhat marked by increased polarization.
In all, I believe every person is a perpetrator at some point when it comes to using a confirmation bias. We all second guess ourselves and try to convince ourselves that we made the best decision possible in our actions. It is a bias that we are all guilty of, but it is important to be aware of one’s biases instead of becoming ignorant.
It just, likes many medicines, involves much trial and error and limitless moral ambiguities before it can reach the point of being beneficial. Darwin and his theory of evolution, Mendel and his peas, and even Fleming and his penicillin were all seen as blasphemous at their beginning. Every discovery in all of history was made with considerable risk factors. Even early medical practices—especially early medical practices—were profoundly hazardous. However, this is the one area in which humanity notably excels—we are endlessly reckless, foolish, and just a tiny bit brave. We all have a fear that dominates us, but humanity is extraordinary in that it is capable of overcoming that fear and surpassing all expectations nature had had for us to get to where we desired to go. We’re all a bit insane to push ourselves until we break—but then we discover new ways to glue ourselves back together, as well. Therefore, yes, the past is important. It shows us where we started from and the limits we have discovered, but it also shows us how far we’ve come. That’s why we have the future, too—to see how much further we can go. We may have limits...but no one knows where they are until we hit them. To the future and
I really enjoy reading the article “You Are Not So Smart” the article really brought up some valid points about “Confirmation Bias” with using examples of our everyday life. There were many interesting piece of information from the article, but there was a few that really drew my attention. For instance, where the teaching confirmation bias in classroom where numbers were involved. The example is followed when the teacher show the students three different numbers, where they have to guess what the numbers were and why they are in a certain order as well as to guess the secret that the teacher used to select these number. Then the students were asked to come up with their own three numbers with the same method that they think that was used throughout
In this experiment, we will investigate whether previous participation in a confirmation bias experiment plus full knowledge of confirmation bias and the Wason 2-4-6 paradigm will lead to a higher initial success rate with future testing. A confirmation bias usually occurs when participants are trying to confirm their beliefs during an experiment. During these experiments, participants results varied between confirmatory and disconfirmatory. The Tukey HSD that was performed for the experiments showed some significance in certain areas. For instance, there was a statistical significance for the total number of guesses between rule one and rule three. More simply, in the first experiment the results showed participants used confirmatory method more for rule one than rule three. For the second experiment participants had more knowledge about the experiment, so their use of the confirmatory method decreased. However, in the second experiment participants used disconfirmatory more for rule three than they did in rule one. Furthermore, all the experiments were similar, because participants had to guess a rule based off a three-number sequence.
Lakia Melton Confirmation Bias Assignment 1. An example of a Confirmation Bias would be for instance if a person has a philosophy that majority of left-handed people have more of an advantage in being more artistic and inventive compared to right-handed people. When coming into contact with individuals who are left-handed there theory is they automatically have a more benefit then a person who is right-handed. When supporting this theory the individual might seek to look at various evidence that shows differences between left and right handed people. 2.
This is a tendency for people to search out data that supports a pre-imagined conviction about the candidate that has been formed before the interview. This implies interviewers hope to affirm a potentially shallow impression they may have formed of the candidate pre-interview, rather than having a more open point of view toward the competitor's capacities in this area.
Confirmation bias has some truly terrifying implications. It can make people completely bind to the facts around them. In particular, this has negative implications for any study preformed, and for science in general. When preforming any kind of study, it is essential that you go in with no expectation for what you are going to find. I realize that this is somewhat impossible, but in order to have the best study that you can, it is imperative that you come as close as possible. When you go in thinking that you will find something, you will undoubtedly find some evidence that suggest you are right. If you only focus on that it is possible that you will disregard something that could benefit society. Peoples’ disposition to having confirmation bias is a huge setback to
Unfortunately, a human can be biased on incorrect without any knowledge of it. Data-backed treatments help to eliminate error on the part of the clinician.
‘The Ultimate protection against research error and bias is supposed to come from the way scientists constantly test and retest each others results’ – To What extent would you agree with this claim in the natural and human sciences.
