Belief‐bias and labor unions: The effect of strong attitudes on reasoning
研究了153名技校学生对工会的强烈态度如何影响三种推理偏差（判断合理性、对比效应、社会归因），发现社会归因偏差最强，对理解态度与判断的关系有参考价值。
Abstract This study compared three types of reasoning bias associated with strong belief: Judgement of plausibility, contrast effects, and social attribution. Respectively, these relate to bias in the perceived validity and extremity of statements and bias in causal interpretations of actions. Technical college students ( N = 153) in two highly unionized communities completed one scale for each form of bias and a section of the IRC Union Attitude Scale which measured their attitude toward unions. Belief–bias was indicated across all three measures although there were differences in their salience. Social attribution was the strongest type of bias manifested ( r = 0.58, p ⩽ 0.001) and contrast effects ( r = 0.33, p ⩽ 0.001) were a second and third. The implications of these results are explored and future research directions in this new line of study are suggested.
