Read an interesting study on Wired on memory. A small scale study has shown that if you know you have access to data, you’re far less likely to remember it:

If you think a fact is conveniently available online, then, you may be less apt to learn it.

This is amazingly true. I frequently note that people referencing articles they’ve read to me can’t remember the article title, author or where it was published, or the detail of what it said or why it was interesting or funny. But they can remember the search sequence that got them there and find it via Google. Which is a fascinating insight into human psychology, right there – the journey is more memorable than the destination.

This is one of the reasons why I’m uncertain on social search. People like the solidity of search; the only way to make sure that social search improves on regular search is to somehow confound this pattern – making sure that social search is only a marginal improvement on general, unfiltered search – otherwise people will get frustrated by not being able to find the same things when on different machines.
