Tests and surveys lend themselves perfectly to the internet. You fill in a few questions about yourself and come up, instantly, with some fascinating aspect of your personality that you never knew before, like that you resemble a carrot rather than a lychee, or a Renault Clio rather than a Jensen Interceptor (yellow). They are great fun and are used on dating sites such as Tickle. I did one and came up with an IQ of 148 which I thought a tad excessive, so I did it again and the result was, I'm sure, closer to reality...
More seriously, academics doing research on social mores, behaviour and attitudes can reach a much wider audience, and the results, especially for surveys conducted on internet use, will be that much more valid.
I haven't amused myself with a silly test recently, but I have taken part in a Manchester University survey on privacy on the internet. It's part of a study by Karen Mccullagh as part of her PhD research, which is sponsored by the ESRC and Office of the Information Commissioner, UK.
The reason why I'm plugging it here, is that it is specifically aimed at bloggers and the content of their blogs - how much they divulge of their private lives, jobs, name and so on, or whether the nature of their blog is based on information about others and their lives, politics, fashion (such as GoFugYourself).
There are also questions on what types of information you consider to be sensitive and whether you have ever got into trouble because of something you included in your blog about someone else or your job.
It takes less than 5 minutes to do, so if you'd like to participate, the link is here.
Karen will send you the results of the survey if you request them. Go on, do it - the more the merrier!
