So I did this in fron of an audience of 15.
I had 5 audience members do drawings prior to the start.
1 woman I depicted her parents were togther with an equal relationship. I told her she had 2 siblings but she had only 1 sibling. I got that she up in the suburbs and best of all I got that she had a masters degree. She told me it was in Math.
1 Man I correctly told him he was from another country. He was from Costa Rica so that was nice hit. I told him his father dominated the household, another hit. I told him he had 1 sibling, turns out he had 11 siblings. It was a miss but I looked at the picure and it made sense.
I think my hit rate was 70%.
