You can't breed for Niven's Teela Brown, of course, but I'd expect that you could breed for Wiseman-style luck.

For example, when I read The Luck Factor, I mused that the 'lucky' people were probably very high on the Big Five factor of Openness, which like most cognitive traits is partially heritable (40% & 61% of variance, in the 2 studies I have handy), and I also thought some of it sounded like latent inhibition which I would also expect to be partially heritable.
