What is the advantage of a bicameral system?

Question

And if it's so great, why not multicameral?

Answer 1

A bicameral system in legislatures allows representation of different interests, and differing views that insulate government from rash decisions taken in the heat of the moment. It is, as someone humorously remarked, like a saucer, allowing the coffee to cool before being consumed.

In response to propsals by Thomas Paine for a one-house leiglslature elected by the people, ". . .When Americans set
about establishing their new state governments, they
showed little inclination to choose the “simple democ-
racy” that Paine argued for. The greater number chose
to establish bicameral legislatures; and only in Penn-
sylvania, where a radical spirit dominated, did the
Constitution provide for a unicameral legislature, with
annual elections and rotation of office. The Pennsyl-
vania Constitution was subjected to immediate attack;
first, by those who argued that only in a bicameral
legislature would wealth and talent be duly repre-
sented; second, by those who insisted that the existence
of two houses simply gave an additional guarantee
against hasty and ill-considered action. "

Multicameral sounds like a humorous idea of ultimate stalemate, and nothing ever gets done about anything. It has all the drawbacks of delay and procrastination, without the advantages of serious consideration of proposals.
