From The Journal of Improbable Research:
If you a reader, collector, participant, or are in any other way connected to, or interested in Celebrity Chefs’ Cookbooks you may have found yourself wondering whether the chefs pictured on the book covers predominantly tend to present their right cheek to the camera or their left cheek?
In that case, thanks to Dr Annukka Lindell of the Department of Psychology and Counselling, La Trobe University, Melbourne, Australia, you now have information at hand to assist your research.
