Experimental Study of Discrete Degree of Sampled Alternatives to Dynamic Decision

Sequential observation and selection problem is a class of dynamic information search and decision process.On the theory ground of bounded rationality and behavioral decision,there is logical causality between alternative's characteristic information and decision-making.By using the descriptive method of laboratory experiment,we found that discrete degree of alternative's quality can impact on Decision-maker's judgment psychology and decision behavior.There is a negative causality between global discrete degree of sampled applicant s and search number,and a positive causality between local discrete degree in that applicant and probability of selecting the candidate.Additionally,people often overestimate their ability to win with obvious over-confidence bias.
