Character

When we refer to an individual's character it's usually the good qualities we want to highlight.  Every person has their share of bad qualities too.  Increasing the "good" qualities and decreasing the "bad ones" may or may not be wise.

It's easier to recognize when an individual is "out of character" the longer they're known.  An individual can recognize their own change in behavior when thoughtful or self-aware.

Knowing when those moments happen provides an opportunity to "reflect" or "apologize".  Not realizing or acknowledging them results in the opposite or something backward.

There may or may not be "methods" or "procedures" to bypass all that.  It may be as simple as a "stage hypnotist" putting "volunteers" in a "trance" and then "instructing" them to collect "imaginary chickens" from the crowd.

Does it have any effect at all?

The "subjects" or "volunteers" will scoop up "imaginary chickens" until told to stop.

How many of them notice they're doing something "out of character"?
