Preliminary analysis of the effects of confirmation bias on software defect density
Gül Çalıklı, Ayşe Bener · 2010
In cognitive psychology, confirmation bias is defined as the tendency of people to verify hypotheses rather than refuting them. During unit testing software developers should aim to fail their code. However, due to confirmation bias, most defects might be overlooked leading to an increase in software defect density. In this research, we empirically analyze the effect of confirmation bias of software developers on software defect density.
