Than you so much for all the excellent liar info yesterday. I’m now halfway through Paul Ekman’s Emotions Revealed: Recognising Faces and Feelings to Improve Communication and Emotional Life and finding it extraordinarily useful. Thanks to Gwenda Bond, Jenny Davidson and Malcolm Tredinnick for suggesting him. I’ll be chasing down all the other leads as well. You are all the best research assistants ever!

Since you were all so amazingly helpful on yesterday’s research question I have another:

Last year (I think) I read at least two articles about DNA testing being used in a classroom (or possibly classrooms) in California (but I may have the state wrong) to demonstrate that no one is racially “pure” and, indeed, to promote discussion about what race even is. The test gives the percentage of your DNA that comes from Africa, Europe, Asia or Native America. And many people get results they’re not expecting. The correlation between your skin colour and your DNA is not straightforward.

I have googled any number of combinations and have found articles on DNA testing and race. Even on DNA testing being taught in the classroom, but not on DNA tests being used to talk about race in the classroom.

If any of you can help with this I will be eternally grateful.
