Lacking method, order, or systematic arrangement; disorganized and unsystematic.
From Greek 'a-' (not) + 'methodē' (method, order) + '-ical' (adjective suffix). This term emerged in English around the 17th century to describe chaotic or disorderly conduct or thinking.
While 'methodical' sounds like someone following a recipe precisely, 'amethodical' is the person who throws ingredients together hoping for the best—and somehow it occasionally works out, which is why amethodical thinking can occasionally produce creative breakthroughs.
