Thanks for telling me about the 'all' and flip strategies. I'm using it right now.

Just started a new game (Thalan, obscene and large/common, very slow research) and I had a bad starting location squeezed between two aggressive races. I did a decent colony rush, but my military and tech were lagging far behind the AI. A bunch of the AI started blackmailing me for money. I was so weak that I was forced to pay off some, but they kept asking for more and more.
I soon realized that I would never build a reasonable military in time before they attacked. I flipped all production tiles to all research and tried desperately to get tech, especially more diplomacy, planetary invasion and spin control center. Unfortunately, the Arcean finally got annoyed me and declared war. This was a problem because the Arcean had by far the best starting location and was leading every category.
I had a merry time using my now superior diplomacy to convince all the other races to attack the Arcean.
That worked out so well that I decided to convince every other AI to declare war on everyone else. So it's an all out war for everyone except me. I'm free to focus on just the Arceans, while he's trying to fend off enemies from all sides.
All the AI other than the Arceans have better relations with me as well.
If I hadn't gone to 'all research' and gotten a bunch of techs and diplomacy, I would have died a quick and painful death.
