““Marc-André Reinhard and his colleagues found that the ability of student judges to detect deception improved drastically if they were given time to think—but only if, in that time frame, they thought about something other than the case they were judging. If they had to make an immediate judgment, they did no better than chance. The same was true if they were allowed to deliberate consciously. But when they were kept from consciously deliberating, by, for example, completing a demanding word-search puzzle, their accuracy improved significantly.””
