For the past several months I've been doing a lot of work/research on women and design to see which design elements are most persuasive for women.
After reading Gender, Design and Marketing by Gloria Moss, I thought I'd take my new knowledge based on her book plus my own research and do a completely unscientific test at an art show.
My test was simple -look at a painting and guess whether the artist was male or female. (Then look at the caption to see if the name was male or female). The great thing about this art show was, all the paintings were the same size - so there was some uniformity, which made the research a little easier. (Rather than trying to take size, material, etc. into consideration).
I wasn't enough of a geek to keep an actual tally of how many I got right or wrong. It was a spur of the moment idea. But it felt like my success rate was better than 50/50.
