Abstract

There is evidence that people vote for corrupt candidates even when they have information that their representatives have been engaged in corruption in the past. Based on a survey experiment in Brazil, we find evidence that ideology is an important factor to explain this voting behavior. We also found evidence of two psychological mechanisms that explain this effect: a change in perception of corruption and a cognitive cost-benefit evaluation. This study expanded previous findings, showing that ideology can affect voting behavior when there is information about corruption even in a country where voters are supposedly less loyal to a single party.

为什么选民选择腐败的候选人？意识形态在认知机制中的作用

摘要

有证据表明，即使人们知道其代表过去曾从事过腐败活动，人们仍会投票给腐败的候选人。根据巴西的一项调查实验，我们发现证据表明意识形态是解释这种投票行为的重要因素。我们还发现了两种解释这种效果的心理机制的证据：腐败感的改变和认知成本效益评估。这项研究扩大了以前的发现，表明即使有选民对单一政党的忠诚度较低的国家，当存在有关腐败的信息时，意识形态也会影响投票行为。
