For both basic and clinical research, however, low rep- licability of findings has recently been reported. Replicability may be affected by research biases not sufficiently con- trolled for by the existing research standards. Several biases such as researcher allegiance or selective reporting are well-known for affecting results. For psychotherapy and pharmacotherapy research, specific additional biases may affect outcome (e.g. -
The Case of Sequential Testing James WB Elsey, Anna I. Filmer, Lott
1 Don’t Forget the Psychology in Psychological Analyses: The Case of Sequential Testing James W.B. Elsey, Anna I. Filmer, Lotte E. Stemerding Author Note Department of Clinical Psychology, University of Amsterdam, Amsterdam, Netherlands This manuscript was supported by salaries and departmental funding from the University of Amsterdam, and by Prof. Dr Merel Kindt's ERC Advanced Grant 743263. 2 Abstract Sequential testing enables researchers to monitor and analyze data as it arrives, and decide whether or not to continue data collection depending on the results. Although there are approaches that can mitigate many statistical issues with sequential testing, we suggest that current discussions of the topic are limited by focusing almost entirely on the mathematical underpinnings of analytic approaches. An important but largely neglected assumption of sequential testing is that the data generating process under investigation remains constant across the experimental cycle. Without care, psychological factors may result in violations of this assumption when sequential testing is used: researchers’ behavior may be changed by the observation of incoming data, in turn influencing the process under investigation. We argue for the consideration of an ‘insulated’ sequential testing approach, in which research personnel remain blind to the results of interim analyses. We discuss different ways of achieving this, from automation to collaborative inter-lab approaches. As a practical supplement to the issues we raise, we introduce an evolving resource aimed at helping researchers navigate both the statistical and psychological pitfalls of sequential testing: the Sequential Testing Hub (www.sequentialtesting.com). The site includes a guide for involving an independent analyst in a sequential testing pipeline, an annotated bibliography of relevant articles covering statistical aspects of sequential testing, links to tools and tutorials centered around how to actually implement a sequential analysis in practice, and space for suggestions to help develop this resource further. -

Illusion and Well-Being: a Social Psychological Perspective on Mental Health

Taylor Jonathon D. Brown University of California, Los Angeles Southern Methodist University Many prominenttheorists have argued that accurate perceptions of the self, the world, and the future are essential for mental health. Yet considerable research evidence suggests that overly positive self- evaluations, exaggerated perceptions of control or mastery, and unrealistic optimism are characteris- tic of normal human thought. Moreover, these illusions appear to promote other criteria of mental health, including the ability to care about others, the ability to be happy or contented, and the ability to engage in productive and creative work. These strategies may succeed, in large part, because both the social world and cognitive-processingmechanisms impose filters on incoming information that distort it in a positive direction; negativeinformation may be isolated and represented in as unthreat- ening a manner as possible. These positive illusions may be especially useful when an individual receives negative feedback or is otherwise threatened and may be especially adaptive under these circumstances. Decades of psychological wisdom have established contact dox: How can positive misperceptions of one's self and the envi- with reality as a hallmark of mental health.

Concepts and Implications of Altruism Bias and Pathological Altruism

Running Head: Transformational Psychology and Reducing Bias
RUNNING HEAD: TRANSFORMATIONAL PSYCHOLOGY AND REDUCING BIAS Using Transformational Psychology to reduce bias and maintain the ethical practice of forensic mental health evaluations 2018 Christian Association for Psychological Studies International Conference.

However, there is evidence that bias exists in the clinician’s opinion due to a myriad of issues. Clinicians are often unaware of their bias due to the phenomenon called the “bias blind spot.” Promoting ethical forensic psychological practice requires the clinician to do what is necessary to reduce bias. The “Transformational Psychological View” proposed by Coe and Hall (2010) can provide a framework for the Christian mental health clinician to aid in the reduction of the bias blind spot. The “Transformational Psychology View” suggests that the practice of psychology begins as an act of love. This concept interfaces well with the practice of psychotherapy, but performing forensic evaluations poses new challenges to acting in love towards your patient. How do we love those that are deplorable in our site and have hurt others who are innocent? Do we act with love towards the patient or the victims of the patient’s crimes or abuses? How can we use compassion to minimize bias due to the clinician’s reactivity from a sense of justice, morality, or faith? This paper proposes that doing the forensic evaluation as an act of love will reduce bias. -
1 Embrace Your Cognitive Bias
1 Embrace Your Cognitive Bias http://blog.beaufortes.com/2007/06/embrace-your-co.html Cognitive Biases are distortions in the way humans see things in comparison to the purely logical way that mathematics, economics, and yes even project management would have us look at things. The problem is not that we have them… most of them are wired deep into our brains following millions of years of evolution. The problem is that we don’t know about them, and consequently don’t take them into account when we have to make important decisions. (This area is so important that Daniel Kahneman won a Nobel Prize in 2002 for work tying non-rational decision making, and cognitive bias, to mainstream economics) People don’t behave rationally, they have emotions, they can be inspired, they have cognitive bias! Tying that into how we run projects (project leadership as a compliment to project management) can produce results you wouldn’t believe. You have to know about them to guard against them, or use them (but that’s another article)... So let’s get more specific. After the jump, let me show you a great list of cognitive biases. I’ll bet that there are at least a few that you haven’t heard of before! Decision making and behavioral biases Bandwagon effect — the tendency to do (or believe) things because many other people do (or believe) the same. Related to groupthink, herd behaviour, and manias. Bias blind spot — the tendency not to compensate for one’s own cognitive biases. Choice-supportive bias — the tendency to remember one’s choices as better than they actually were. -
The Effects of Expertise on the Hindsight Bias
The Effects of Expertise on the Hindsight Bias A Dissertation Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Melissa A.Z. Marks Knoll, B.A., M.A. Graduate Program in Psychology * * * * * The Ohio State University 2009 Dissertation Committee: Dr. Hal R. Arkes, Advisor Dr. Thomas E. Nygren Dr. Michael C. Edwards ABSTRACT I present data from three experiments in which I explored the effects of expertise on the hindsight bias. In Experiment 1 participants read an essay about baseball or about owning a dog and then answered a 20-question true/false quiz about the baseball essay to the best of their ability (do-your-best group), as if they had not read the essay (discount group), or to the best of their ability even though they read about owning a dog (dogs group). Participants also completed a quiz about baseball rules (measure of expertise). Results demonstrated that as participants’ baseball expertise increased, their inability to act as if they had never read the essay also increased; expertise exacerbated hindsight bias. In Experiment 2, varsity baseball players and baseball non-experts answered a 20- question quiz about baseball current events. Foresight participants answered the questions, while hindsight participants were given the questions and the answers and had to give the probability that they would have known the answers had the answers not been provided. The baseball players displayed no hindsight bias, while non-experts demonstrated the bias. To test of the effects of subjective expertise on hindsight bias, participants in Experiment 3 ranked five topics in order of expertise and gave feeling-of- knowing (FOK) ratings for 100 questions from these topics. -
The Truly False Consensus Effect: an Ineradicable and Egocentric Bias in Social Perception
Journal of Personality and Social Psychology Copyright 1994 by the American Psychological Association, Inc. 1994, Vol. 67, No. 4, 596-610 0022-3514/94/S3.00 The Truly False Consensus Effect: An Ineradicable and Egocentric Bias in Social Perception Joachim Krueger and Russell W. Clement Consensus bias is the overuse of self-related knowledge in estimating the prevalence of attributes in a population. The bias seems statistically appropriate (Dawes, 1989), but according to the egocentrism hypothesis, it merely mimics normative inductive reasoning. In Experiment 1, Ss made population estimates for agreement with each of 40 personality inventory statements. Even Ss who had been educated about the consensus bias, or had received feedback about actual consensus.or both showed the bias. In Experiment 2, Ss attributed bias to another person, but their own consensus estimates were more affected by their own response to the item than by the other person's response. In Exper- iment 3, there was bias even in the presence of unanimous information from 20 randomly chosen others. In all 3 experiments, Ss continued to show consensus bias despite the availability of other statistical information.
