Anchoring and Bias
ثبت نشده
چکیده
For example, in one study subjects were asked to give the percent of African countries in the United Nations. In each case, a number between 0 and 100 was assigned as an initial value and the subject was asked if this was too high or two low, and what adjustment needed to be made. Despite the fact that each of the subjects knew that the initial value had been determined randomly (by spinning a wheel in the subject’s presence), there still tended to be a bias toward the initial value.

Is the 52-high-price Strategy Explained by Behavioral Finance? (Uncertainty Effect)
The aim of this study is to investigate a behavioral approach by anchoring bias as a criterion to explain 52-week-high strategy and trough this we can find an explain for momentum strategy at uncertainty situation, to the companies listed on the Tehran Stock Exchange. The information uncertainty criteria include the book value to market value (BV / MV), company age (Age), the size of the entity...
متن کاملRelative influence of anchoring and centering biases in reconstructive memory
We report the results of an experiment probing the relative influence of centering and anchoring biases in reconstructive memory for line lengths. On each of 90 trials participants (N=120) viewed a target line, which they reproduced after a delay by adjusting a response line. We manipulated the starting size of this response line in three conditions: one provided an anchoring bias opposite the ...
متن کاملCountering the anchoring and adjustment bias with decision support systems
Psychologists have identified several limitations to, and biases in, human decision-making processes. One such bias is the anchoring and adjustment effect, which has been demonstrated to be robust both inside and outside the experimental Ž . laboratory. Some decision support systems DSS have been designed to lessen the effects of decision-making limitations with promising results. This study te...
متن کاملInfluence of the bias-voltage on the anchoring energy for nematic liquid crystals.
The influence of the bias-voltage on the anisotropic part of the nematic surface energy is analyzed. The experimental data show a strong dependence of the anchoring strength on the bias-voltage when the electrodes of the nematic cell are covered with WO3. The observed dependence can be interpreted taking into account the ions dissolved in the liquid crystal. We propose a model in which the effe...
متن کاملIndividual differences in anchoring: numerical ability, education and experience
Anchoring is a well-known effect leading to bias in estimation in various decision-making contexts. A question, however, is whether individuals with greater numerical and academic ability would be less prone to this effect than others because of greater ability to discern the value being estimated. In light of growing interest in the role of individual differences in bias susceptibility, anchor...
متن کاملAssessing the Effectiveness of Anchoring Vignettes in Bias Reduction for Socioeconomic Disparities in Self-Rated Health among Chinese Adults.
This study investigates how reporting heterogeneity may bias socioeconomic and demographic disparities in self-rated general health, a widely used health indicator, and how such bias can be adjusted by using new anchoring vignettes designed in the 2012 wave of the China Family Panel Studies (CFPS). We find systematic variation by socio-demographic characteristics in thresholds used by responden...
