This is more than likely a result of the mass media sensationalism I.e. Most passengers think that any minor malfunction on an aircraft means scream for your life before almost certain terrifying death. Which couldn't be more wrong.
I don't envy any cabin crew trying to stop a stampede of media-frightened passengers from trying to access doors before any evacuation has been decided.
