Keep those prospective jurors talking
Years ago when I was a young attorney I would cringe during voir dire if a prospective juror gave a negative opinion of anything that had to do with my case. I would either quickly move on to another prospective juror or try to convince the first juror that they were wrong. Those are the wrong things to do. You want that juror to talk and give you all the negative opinions they have without being afraid of those opinions. The opinions are information. They tell you how that juror thinks and that helps you to possibly challenge the juror for cause or make a wise preemptory challenge. The prospective jurors you should be afraid of are the ones that are quiet.
