Having $1000 pre-filled makes me feel uncomfortable. I can understand the reasoning behind anchoring to a higher number, and I can’t explain much behind why it makes me feel uncomfortable about contributing at all. Perhaps a running average pre-fill like the indie game Humble Bundle 3 would be better.
The method of donation will change what you see: the Causes.com form started with a pre-fill of $25.
The Humble Indie Bundle team actually did A/B testing with multiple donation forms, one of which included a set dollar amount, another which included rolling average, and at least one other. Such testing may show that a running average would discourage large donors, thereby reducing overall donations.
I’m not sure if this is bad word choice, but if you genuinely don’t know the results then it seems disingenuous to focus on one of the three specific results without offering any further support for that stance. (If you do know the results then I would love to see them ^.^)

I don’t know the results of their testing. It was briefly discussed on Hacker News.
A running-average pre-fill sounds much better to me.
