Referees for high‐energy theoretical papers are now selected by the Chinese restaurant system. The editors of Physical Review Letters select one referee from Group A and one from Group B. The groups were established when one theorist complained that a paper sent to the wrong referee would be automatically rejected. It is still not clear which group any particular theorist belongs to. Perhaps the criterion is simply that first suggested by Richard Feynman: highenergy physicists fall into two categories—either they group or they disperse.
