When saying that you are biased means that you are acurate? The moderating effect of cognitive structuring on relationship between metacognitive self and confirmation bias use

The aim of our study was to answer two questions: 1. How accurate are the reports of people who assert they are biased? 2. Why do people who know they are biased tend to engage in more inappropriate behavior? A total of 340 undergraduate students participated in the study. They followed a special procedure measuring cognitive structuring, efficacy to fulfill personal need to achieve cognitive structuring, metacognitive self (i.e. self-awareness of biases), and the level of performed confirmation bias. The procedure was created for investigating confirmation bias concerning the perception of self versus others. The first question may be answered by the assertion that the more metacognitive self-awareness of biases a person possesses, the more confirmation bias they exhibit. The pattern of results concerning the second issue demonstrates that only efficacy to fulfill personal need for structure (EFEN) moderates the relationship between metacognitive self and confirmation bias. Thus, only low-EFEN individuals perceived the extent of their use of biases more accurately. We explain the effect in terms of cognitive processing style: an individual inclination for piecemeal processes.
