Why are people unable to keep confidences?

It seems to me that lately people have, in general, gotten worse at
keeping confidences. I'm not sure if this started from the Monica
Lewinsky scandal when her "friend" recorded her phone conversations,
but in the current reality, people just seem to assume that anything
they are told, they are free to pass on to anyone they please. What
this has led to, in my opinion, is an environment where people no
longer have anyone to talk to.

In a recent Time magazine issue, there was an article stating that
people have fewer and fewer close friends, which leads to them not
having people to talk to. Maybe it is not that we have fewer
friends, but we no longer know what that means. IMHO, one of the key
requirements of being a "friend" is to assume that anything that is
shared with you is by default something that should be kept
confidential, instead of being something that you should share with
everyone and anyone they feel like.

Maybe instead of looking for more friends, we should try to be better
friends and learn to keep confidences confident.
