This is an interesting topic which talks about how certain psychological behaviors and biases alter our day to day decision making as testers and impact overall quality of the software. This session will enlist these behaviors, for example : Ellsberg paradox and Congruence bias and how they impact testing. Just like every other cognitive bias the first remedial step is to be aware and conscious of their existence and have processes which circumvent these biases. As part of this talk, I will also discuss these remedial processes. Resources required : projector for the slide deck Max attendees : Anything Expected outcomes : Attendees can go back to their teams and make everyone aware of these biases and use the remedial processes to improve software quality.
