Just as car insurers can predict claims activity better from FICO than they can from driving record*, so FICO can tell you a tremendous amount about a woman.

FICO teaches you her self-control, self-accountability, future time orientation, her potential for self-delusion and magical thinking, and family quality. Her IRA and 401k balances will tell you if she's advanced beyond simply staying afloat in the harsh sea of life (good FICO) to actually swimming towards the shore.
