In one of Bernard Kettlewell's peppered moth studies, his moth recapture rate increased greatly beginning on July 1. July 1 was also the date on which E. B. Ford sent Kettlewell a letter commiserating with him for the low recapture rates. This suggests that Kettlewell cheated to increase his recapture rates.
Bernard Kettlewellのオオシモフリエダシャクの研究の一つで、彼のオオシモフリエダシャク再捕獲率が7月1日に、大きく増大し始めていた。7月1日は、E.B.FordがKettlewellに、彼の低い再捕獲率に同情する手紙を送った日である。これは、Kettlewellが再捕獲率を誤魔化したことを示唆している。
