As the saying went, even an upright official found it hard to settle family disputes. At its core, that was because people unconsciously embellished their own actions when speaking. No matter how capable a judge was, they could not make people tell the whole truth, and so each side inevitably claimed to be in the right.
But determining who was actually right was far too difficult, and both sides understood that perfectly well. That was why they dared to lie without restraint.
However, in the DC Universe, there was a Divine Artifact practically made for settling family disputes: the Lasso of Truth.
After Bruce learned from Diana of his own universe that she possessed such a useful thing, he often borrowed the Lasso of Truth to mediate household conflicts.
For example, who had taken whose belongings between Jason and Tim; whether Dick's homework notebook had really been chewed up by Aisha; and who had brought Assault Cabbage to school and sent the principal to the hospital.
Through his extensive experience using it, Bruce discovered that the Lasso of Truth was not very useful for questions that were too complicated, because even without lying, there were many ways to answer truthfully.
But for yes-or-no questions, the Lasso of Truth was astonishingly effective. With only yes and no as possible answers, there was no way to obscure the point. As long as the question was properly phrased, it could yield an answer with an accuracy rate close to one hundred percent.
Wonder Woman signaled Bruce with her eyes, and Bruce prepared to begin questioning them.
"Do you understand the other person?"
"Yes." "Yes."
Overlord Superman answered first, and Batman answered afterward. Clearly, Batman had greater resistance to the Lasso of Truth.
"Then do you think the other person understands you?"
"No." "No."
