Is satisficing conceptualised as being unconscious/automatic, or conscious/volitional?
Satisficing is goal directed and satisficers intend to achieve satisfactory results. Therefore, satisficing seems to involve conscious choices being made. 

However, in Unconscious Thought Theory (UTT), unconscious thought produces superior decisions compared to conscious thought when decision making is complex and there are paragraphs of Nelson and Winter (1982) that indicate that satisficing can be achieved from a sequence of mechanical, automatic steps of rule following.

Therefore looking at both H.A. Simon's conception and the findings from Nelson and Winter, satisficing can be either conscious or unconscious.
