How often do teams start to work with biological model systems without knowing the fundamental biology of species concerned or without directly consulting experienced people? To understand the functioning and evolution of a local model system with unique spatio-temporal characteristics, observation and experience will ultimately be more important than the knowledge from libraries dealing with model systems that express other characteristics. It is therefore unlikely that laboratory directors overloaded with administration tasks, or any citizen without adequate background knowledge, can identify a feasible science topic among a multitude of options defined by experts. Citizens might base reasoning on one observation (an anecdote) and think this may apply to any situation. But is this true?
