Petals Around the Rose: Fraternity Register

Two throws. Sent this to several friends with a request to tell me how long it took to figure it out, and it appears that those who daily deal with "big picture" issues get it quickly, those who work with abstract theory or detail take longer. Nothing to do with innate intelligence. For example, these folks got it within 10 min: commercial banker, classical musician, charity case manager, wine buyer, retired businesswoman. These took significantly longer, or in a couple of cases are still stumped: med school professor, CPA, mechanical engineer. The exception is a nuclear sub specialist, who got it immediately. Anyhow, my hypothesis is that a tendency to "drill down" with data analysis and algorithms doesn't help in this situation, while a more expansive problem-solving approach works.
