I wish! Though implementation would be tricky and might heavily politicize science in a bad way (as opposed to a good way; which could also happen). The closest I've seen anywhere to that is in Kim Stanley Robinson's Mars Trilogy.
Here's an excerpt from the "Martian Constitution" in the accompanying book "The Martians":
"""All laws passed by the congress shall also be subject to review by the constitutional and environmental courts, and a veto by these courts cannot be overridden, but shall be grounds for rewriting the law if the congress sees fit, after which the process of passing the law shall begin again."""
Good find. I remember the constitution they hammered out in the books was interesting, as there was a lot of Aldo Leopold "think like a mountain" stuff.
(Of course, in the book, they've discovered a genetic repair mechanism that effectively makes people immortal, so I suppose it's still self interest)
