归纳推理的多样性效应及其机制探索

归纳推理结论范围大于前提范围的这一特点决定了归纳结论的不确定性，寻求前提的多样化是增强结论可靠度的重要途径。已有研究通过寻找证据、力度判断、特征扩展与归宿选择等研究方法发现前提类别覆盖范围、前提概率原则可以较好地解释多样性的内在机制。事实上，多样性效应的实质是大数原则在归纳推理中的运用，其产生的心理过程包括差异识别、大数信息抽取与大数信息运用三个步骤

Diversity Effect and It's Mechanism of Inductive Reasoning

The conclusion of inductive reasoning is uncertain because the range of conclusion is broader than the range of premise. One approach of increasing the certainness of induction is searching diversiform premise. By the methods of searching evidence, giving judgement, extending feature, and choosing host, researcher found that the mechanism of diversity can explained by the much category coverage, rule of probabilityo In fact, the diversity effect is the consequence of implication of and the law of large numbers, which include distinguishing the difference of premise objects, detecting category information and abstracting numerical difference between diverse premise and non-diverse premise, using large number in increasing strength of conclusion.
