Specially if the interest in the date has decreased, you don't know very well to your date and in order to avoid gaps in the conversation.

I had a date yesterday with a Venezuelan woman of 26 (a 7 out of 10) and she didn't have any conversation at all and to use one of these tests would have saved me.

I used the cube test and the forest test (the one where a mug is included and a table) 12 years ago, and I have realised there are loads of tests such as the Japanese tests based in The Kokology Book.

Which is your favourite one?
