People realized that knowledge is power very early on and the phrase is often attributed to Sir Francis Bacon, an English philosopher and statesman who served as Attorney General (1613-1617) and as Lord Chancellor of England (1617-1621).
Not everyone possesses the same knowledge, but not everyone is allowed to. At the same time, there are things that you think you shouldn’t know because it’s not your place, but actually it’s not classified information, it just sounds like it.
If you would like to hear some examples of such information, this list contains all sorts of cases when people think that it’s almost illegal to know what they know. The thread started when craftygalcreates asked “What’s a piece of information you learned that now feels almost illegal to know?” In two days, the question got almost 40k upvotes as people were interested to read the secrets that are not really secrets.
When I was a kid, my dad taught me how to pick a lock. I became very interested in different kinds of locks and purchased a lock pick set. I practiced for years and became pretty good at certain types of locks. So over the years every now and then, if a neighbor locks themselves out of the house or a friend loses the key to a padlock or a lock box I’ve been able to help. But the reactions I tend to get from people, even while I’m helping them with their lock is mainly one of mistrust. I’m not a cat burglar. I just like locks.
