What do physicians have in common with pilots?

They both respond to performance metrics (hand-washing or physicians; fuel consumption for pilots)--even without a reward (or penalty)!

PHYSICIANS:
METHOD:
The ICU unit coordinator was trained to observe and measure hand hygiene compliance. Data were collected on hand hygiene compliance at room entry and exit for 9 months. Percentage compliance for each medical and surgical subspecialty was reported to chiefs of service at the end of each month. Comparative rankings by service were widely distributed throughout the physician organization and the medical center.
RESULTS:
The hand hygiene compliance rate among physicians increased from 65.1 % to 91.6 % during the study period (p <0.0001). More importantly in the succeeding 24 months after study completion, physician hand hygiene compliance remained >90 % in every month.
PILOTS:  Another randomized controlled trial from Randomistas:
...Working with the pilots' union the researchers reassured pilots that they would not be ranked against each other:  "This is not, in any way, shoape or form, an attempt to set up a 'fuel league table'" the letter told them.  Despite knowing this, pilots who received monthly reports on their fueld efficiency ended up guzzling les gas than pilots who did not receive such reports.  The feedback was purely private, yet it lead pilots to tweak their behavior.  With an experiment that cost less than $1000 in postage, Virgin Airways cut its fuel consumption by about 1 million litres.
