Sometimes it’s almost impossible to understand things people do and why.

These may be actions taken or even glaring omissions. Some behavior just seems unforgivable.

When you glimpse inside most families many such events are often visible. But sadly, equally incomprehensible behavior is often present in the workplace, too.

The more shocking or radical the act, the more important it is to understand and/or correct.

Many times our superficial observations offer insufficient clues. And worse, reports and surrounding insights available do little to explain an event or illuminate its root cause.

When I’ve run into such circumstances in the past I’ve always found one piece of homespun wisdom invaluable in getting me to the heart of the matter.

Many years ago I learned the expression, “All bad behavior is based in insecurity.” I originally heard this from a seasoned manager. I’ve never really convinced myself of its true origins; but no matter.

Perhaps you have seen more recent, interesting variations and derivatives of this theme:

• “The hallmark of insecurity is bravado”

Brandon Sanderson

• “Most bad behavior comes from insecurity”

Debra Winger

• “I’m interested in the fact that the less secure a man is, the more likely he is to have extreme prejudice”

Clint Eastwood

I still prefer my original version when I’m faced with insufficient facts to explain unfortunate events. It causes me to look from a different angle and quickly perceive the likely root of bad behavior on display.

All people have insecurities. It is the nature of being human.

So inevitably, we should expect everyone will exhibit bad behavior eventually.

When an individual makes such an exhibition (or alternatively fails to take proper and expected action) their insecurities are invariably on show.

If you approach deciphering a confusing behavior with this in mind it will cause you to ask:

• “What is the insecurity that explains this person’s action?”

Likely candidates invariably spring to mind, even more so the greater your existing knowledge of the individual.

The worse the behavior, the more glaring is the insecurity. Just step back and look. Once you spot the insecurity past events are explained and future sensitivities can be managed.

Understanding someone’s problems enhances your ability to empathize and provide practical support if it’s required. At the very least your enhanced awareness allows you to better adjust your own relationship appropriately and advise/guide others.

So, the next time you see bizarre behavior for no apparent reason. Step back. Look for the insecurity. You’ll generally find it in full view.
