This is a slightly modified version of the presentation that I did at BarCamp Canberra #3.
During the actual presentation, I ran an exercise based upon psychologist Bertram R. Forer's experiments (also carried out by James Randi and other folks). Refer to http://www.skepdic.com/forer.html for the words I used in the presentation.
Also please note that the term 'quirkology' was coined by Richard Wiseman (@RichardWiseman). He's written a book also titled Quirkology. The book is a nice easy read - go check it out (particularly if you can get the book with the 'smiles' cover).
