well, the wikipedia article (http://en.wikipedia.org/wiki/Heuristic#Theorized_psychological_heuristics) on heuristics claims five 'well known' heuristics, which they list as 'Anchoring and adjustment, Availability heuristic, Representativeness heuristic, Naïve diversification, Escalation of commitment.'

Good point, though. Maybe a series of posters would be better for this topic.
