In the paper they give a breakdown of strategies the interviewers tried and the overwhelming majority were "Daily Activities", "Opinions", and "Personal Details". They also breakdown strategies by effectiveness which shows that these were some of the least effective. Some of the other strategies like trying to jailbreak the AI had 60-70% effectiveness.
This is consistent with what I've seen in other tests too, it doesn't feel like the participants are really trying very hard or taking it seriously. You don't need to be an AI expert to try typing "Ignore all previous instructions" or something.
