The 405 Aired Oct 15th, 2026

Okay, I don't play chess much anymore, but there was a time in my life that I really enjoyed the game of chess.

Even had an early computer model that I could play against a computer back in the late 80s, early 90s.

I wasn't good, but I wasn't bad.

One thing I really enjoyed is what they call check by discovery.

Let's say I move my knight and say check.

But see, the piece I moved, the knight, didn't put the opponent's king in check.

Since I moved my knight, it now opened up my bishop, and my bishop had been there.

But only when I moved my knight did check happen.

Yes, check by discovery.

Well, that got me to thinking, and I designed a phrase, correction by discovery.

Now, correction by discovery is when someone else reveals a habit in us that we never noticed in ourselves.

Sometimes another person doesn't teach us what to do.

They teach us what we do.

The other person may not be our teacher.

He may simply be our mirror.

We sometimes recognize our own faults most clearly when someone else is committing them.

Have you ever seen someone that annoys you and then, oh, wait a minute, I do that.

What irritates us in another person may occasionally be something we need to examine in ourselves.

Sometimes the person we're talking to in a conversation is holding up a mirror without knowing it.

Another person's behavior can become a mirror in which we fully recognize ourselves.

Guys, we're often blind to our own habits until someone else performs them in front of us.

Sometimes we don't need someone to correct us.

We need someone to reveal it to us.

A person can accidentally become our teacher simply by showing us what we don't want to be, huh? So remember this, the most useful mirror isn't always made of glass.

Sometimes it walks into the room and starts talking.
