This brings up the third and fourth enemies of questioning, which are related to each other: bias and hubris. In terms of biases, some of them are hardwired in us; others may be based on our own limited experiences. But in either case, if we are predisposed to think something, we may be less open to considering questions that challenge that view. The book’s second section, on decision-making, looks at some of the ways we can use self-questioning to better understand and challenge our own biases and assumptions.
