I would imagine asking "When you approach a problem, do you apply any techniques to evaluate any cognitive biases that might be applicable" would elicit some sort of response without upsetting people.

I don't know how important this is for most line employees. As a code monkey, I rarely have some strong bias besides "Angular is my personal preference over React" which immediately leads to "Well, should we use React anyway because the team knows it better and blah blah."
