Apparently Brett Kavanaugh lied during his confirmation hearings about his standing on Roe v Wade. How do we keep this from happening in future confirmations?

Kavanaugh knew exactly what he was saying and alluding to while being questioned. He also knew what a hot button topic it was and made everyone believe he would not attack R v W.
A Supreme Court justice lying to get his job! How do we prevent this in the future? Or can we?
