which do you prefer, rigid or flexible constitution?

Question

rigid constitution requires a long and difficult procedure for ammendment while a flexible constitution is changed like how an ordinary law is changed

Answer 1

As with all liberties and flexilities. It all comes down to how good 'the people' are able to respond in an appropriate manner to change.

You might want to do some research into Hofstede's cultural differences. Things like uncertainty avoidance, masculity. That can explain why certain countries choose for a more rigid model and some for a more flexible one.

Answer 2

A Constitution, by its nature and purpose is not supposed to be flexible. If it is flexible, it is useless.
