Book 26 Quirkology by Richard Wiseman
Subtitled 'The curious science of everyday lives', experimental psychologist Prof Richard Wiseman covers a variety of scientific studies into various bits and pieces of everyday life, including his study LaughLab which supposedly found the world's funniest joke, how you can actually tell if someone is lying, why women should ask a man to write their personal ads (interesting one, that; men turned out to be pretty good at spotting the personal adverts which would appeal to women, but women were rubbish at identifying which personal ads would appeal to men), what your date of birth actually does reveal about you, and a whole load of other quirky studies.
