We all know that decisions shouldn't be made on empty stomachs. The surprise is how much our fates might depend on this truth. Your best chance of getting a “yes” to any request—a raise, a date, a grant, a donation for your charity run—is right after your requestee has eaten. This certainly applies to judicial decisions, finds a study at Ben-Gurion and Columbia Universities
. Right after judges had a food break, they were likelier to agree to a prisoner's request than any other time of the day. Credit the mood-lightening and brain-boosting effects of a short rest combined with a glucose surge. Later, as the judges' blood sugar levels presumably dropped, the “yes” rate plummeted—to nearly zero by the end of a session.
