James Watson's wisdom

I was sucked in to this excerpt (in MIT's Technology Review) from biologist James Watson's soon-to-be-published memoir, "Avoid Boring People." Watson's 5 lessons at the end are particularly stimulating. His assertion that science is best done in teams of no more than 2 is about increasing and diminishing returns: The marginal product of scientist #2 on a team is deemed to be much higher than the MP of scientist #1 acting alone, but beyond that do not go, sayeth Watson. I wonder how true this is today, or how surprised Watson might be by the hundreds of co-authors on the papers laying out the structure of the human genome. Then again, I wonder if Watson would consider the sequencing of the human genome to be science, or just "mopping up the details."
