To conserve energy, our brains habituate or go on autopilot. Respondents often show signs of fatigue, such as mentioning that the questions seem repetitive, or start giving similar responses across multiple questions. Moderators must keep the engagement conversational and continue to vary question wording to minimize habituation. Sponsor bias 3 : When respondents know — or suspect — the sponsor of the research, their feelings and opinions about that sponsor may bias their answers.
Confirmation bias then extends into analysis, with researchers tending to remember points that support their hypothesis and points that disprove other hypotheses. Confirmation bias is deeply seated in the natural tendencies people use to understand and filter information, which often lead to focusing on one hypothesis at a time. To minimize confirmation bias, researchers must continually reevaluate impressions of respondents and challenge preexisting assumptions and hypotheses. Culture bias 5 : Assumptions about motivations and influences that are based on our cultural lens on the spectrum of ethnocentricity or cultural relativity create the culture bias.
Ethnocentrism is judging another culture solely by the values and standards of one's own culture. Cultural relativism is the principle that an individual's beliefs and activities should be understood by others in terms of that individual's own culture.
To minimize culture bias, researchers must move toward cultural relativism by showing unconditional positive regard and being cognizant of their own cultural assumptions. Complete cultural relativism is never percent achievable. He measured cranial capacity by filling the cranium with mustard seed and measuring how much seed each skull could hold.
He performed the measurements himself, knowing which skulls belonged to whites and which belonged to other races. His results confirmed an average cranial capacity of 87 cubic inches for whites, but only 83 cubic inches for Africans.
His study confirmed his theory that intelligence and behavior is controlled more by genetics than by environment. This is called sample selection bias. The best way to select people for research is using the basis of chance, in other words, so that everyone in the population being investigated has an equal chance of being selected. This is called randomisation, because people are randomly selected to take part in the study.
Observation bias occurs when participants in a study are aware that they are being observed by scientists and, either consciously or unconsciously, alter the way they act or the answers they give. Confirmation bias is a type of bias that may occur during the interpretation of study data when researchers, consciously or unconsciously, look for information or patterns in their data that confirm the ideas or opinions that they already hold.
Studies with negative findings i. These 'negative' results are as important for understanding a scientific topic as significant results are but they are less likely to be published. With the growth of the internet, this type of bias is becoming a greater source of concern. The main source of this type of bias arises because positive research tends to be reported much more often than research where the null hypothesis is upheld.
Increasingly, research companies bury some research, trying to publicize favorable findings. Unfortunately, for many types of studies, such as meta-analysis , the negative results are just as important to the statistics. Martyn Shuttleworth Feb 5, Research Bias.
