The BBC has an Internet survey on Brain Sex and if you’ve never taken it, you should go there and try it out. I remember doing this survey a year or so ago and I wasn’t surprised by the results so for me, anyway, it seemed accurate.

The data from the survey has been analyzed and research papers with key findings are being published in the current issue of the Archives of Sexual Behavior. You can read the BBC summaries of the articles at bbc.co.uk.

The survey had over 450,000 participants and 225,000 completed the survey. Some of the conclusions may be considered common knowledge, such as the finding that men rank good looks in a mate higher than women do. But some findings are intriguing. The survey results link spatial processing ability to sexual orientation.

You can take the Sex ID test here. Get a brain sex profile and find out if your brain is more male or more female. Have a ruler handy, because you will need to measure your fingers (really). It’s a revealing test that may help you understand why you think like you do.
