Advice-taking And Judgement In Different Decision Tasks

Advice-taking has become an innovative focus decision-making research in recent 10 years. A mature paradigm, judge-advisor system, has been developed. As adopting of this paradigm, many advice, decision-making and judging related factors have been introduced by previous studies, based on single-advice studies, even expanding to analyzing the strategies of multi-advices. The most common finding was that judges, by using egocentric advice discounting, shift the initial decision value towards the advised value by 20% to 30%. As supplementary research suggested, the judge was "egocentric" and could be "heuristic" by advice. However, no researchers have explored the effect of the difference between the first-decision and advice detailedly. Additionally, former studies focused more on individual experience and knowledge rather than values or personality. The types of decision-making tasks used in the previous research studies were similar. To improve previous studies, this article will implement typical paradigm to discover the different effect of three pair of variables on decision-making, which are estimating task and the risk task, situations of single advice and multi-advices and collectivism and individualism on. There were 258 subjects from three universities participated in the study.The results are as followed:(1) The difference degree between the initial decision and the advice could affect the advice-taking.(2) Under the single advice tasks: (a) As the difference degree between the initial decision value and the advice value increased, the weight of advice was amplified. (b) As growing of the difference between the initial decision value and the advice value, the subject who has higher collectivism value took advice more. (c) Under the risk task, the subject who has higher individualism value took the advice less. Furthermore, the weight of advice perceived by those who have higher individualism value reduced when the difference degree between the initial decision value and the advice value was larger.(3) Under the multi-advices tasks:most subjects tended to accept the similar advices. Additionally, the propensity of using this strategy is lower in the risk task than it is in the estimate task.
