The report explains that you can determine a date's level of curiosity not just by the questions they ask you, but by the questions you ask them. If you say, "How do you feel about your job," and he says, "I don't know" or gives you a vague answer, he's probably not very curious. I know someone who says she can tell a lot about a person by asking them: "What's the best thing that's happened to you this week?" By asking that question you can show off your curios nature while also finding out if your date is curious too.
When you first get to know a person, say on a first date, do you have certain questions you like to ask?
