Prejudice and door lock

Which one is more powerful? A door lock or prejudice?

I encountered 2 broken door lock incidents in the past few days, luckily nothing went wrong. 

One of the door usually requires a smartcard to open, as the system was faulty that day, someone disabled the lock to make sure people have access to it. However I still swipe my card every time when I push an unlocked door…

Here’s an image of a classic InfoSec theory (Which is about “CIA”)

It talks about integrity, availability and confidentially. If you are living in an apartment building in Hong Kong, most of the time if you forgot to lock the door, nothing will happen. The challenge for anyone who’s trying to break in an apartment/system is that there’s a cost for testing each door. Most people will assume a door is “locked”.

How about when we try to share a new idea? Do we assume people will not take it and just drop it? To me, prejudice is much more powerful than a door lock, cause after all, we all assume a door lock can lock the door… but it isn’t always the case.
