In research designed to identify the "quack factor" in modern mental health practice, Norcross et al. (2006) [469] list NLP as possibly or probably discredited, and in papers reviewing discredited interventions for substance and alcohol abuse, Norcross et al. (2008) [470] list NLP in the "top ten" most discredited, and Glasner-Edwards and ...
A good example of this is a study showed that when making food choices for the coming week, 74% of participants chose fruit, whereas when the food choice was for the current day, 70% chose chocolate. Insensitivity to sample size, the tendency to under-expect variation in small samples.
Note that data dredging is a valid way of finding a possible hypothesis but that hypothesis must then be tested with data not used in the original dredging. The misuse comes in when that hypothesis is stated as fact without further validation. "You cannot legitimately test a hypothesis on the same data that first suggested that hypothesis.
The consistent application by statisticians of Neyman and Pearson's convention of representing "the hypothesis to be tested" (or "the hypothesis to be nullified") with the expression H 0 has led to circumstances where many understand the term "the null hypothesis" as meaning "the nil hypothesis" – a statement that the results in question have ...
Deception: Deceive participants about one or more aspects of the research to conceal the research hypothesis. Post-experimental questionnaires: For example, Rubin (2016) discusses the Perceived Awareness of the Research Hypothesis (PARH). [6] [7] This 4-item scale is usually presented at the end of a research session. In responding to the scale ...
The hypothetico-deductive model or method is a proposed description of the scientific method.According to it, scientific inquiry proceeds by formulating a hypothesis in a form that can be falsifiable, using a test on observable data where the outcome is not yet known.
In the ten years after the influential Ross et al. study, close to 50 papers were published with data on the false-consensus effect. [15] Theoretical approaches were also expanded. The theoretical perspectives of this era can be divided into four categories: (a) selective exposure and cognitive availability, (b) salience and focus of attention ...
For Putnam, the working hypothesis represents a practical starting point in the design of an empirical research exploration. A contrasting example of this conception of the working hypothesis is illustrated by the brain-in-a-vat thought experiment. This experiment involves confronting the global skeptic position that we, in fact, are all just ...
