I think the right type of thing are the sorts of questions that get put in buzzfeed lists like “10 questions to find out if your date is the one” and “how compatible are you? 25 questions to predict relationship success with your partner” type things.

The questions are all like “do you like camping”, “would you like to live in a foreign country” etc.

Some questions like this have actually been studied for their predictive ability I think.
