Actuarial Science
  
The science of being an actuary, i.e. assessing risk.
Tons of inputs. And ambiguous r-square correlations with a given set of events. Like...if you get three speeding tickets within 18 months, from a risk correlation perspective, it...means something. Angry driver, maybe? There's a science behind how insurance rates get priced. Do it right (i.e. avoid having big payouts) and you make bank. The exogenous meteor strike is always out there though, just in case you ever start sleeping too soundly.
