We often think we know the people around us well: friends, colleagues, partners… Yet, sometimes all it takes is a simple detail, a fleeting reaction, to reveal an unsuspected side. No need for years of analysis or long speeches: certain subtle signs speak louder than words. Are you curious? Psychology has a lot to say on this subject…
Observing the Invisible: Where True Character Hides
It’s a little phrase that changes everything: « Show me how you treat others when you have nothing to gain, and I’ll know who you are. » Carl Jung, the eminent Swiss psychiatrist, was convinced: our true personality is not revealed in moments of glory, but in the small moments of everyday life, those when no one is really looking at us.
So, where do you start to better understand someone? Here are two key attitudes, as simple as they are revealing.
The first true test of character: selfless kindness

Picture this: At a restaurant, your friend speaks kindly to the waiter… or, conversely, completely ignores them. At a store, your colleague thanks the saleswoman … or sighs loudly when the wait is long . These seemingly innocuous moments are actually powerful indicators of what lies beneath the surface.
When someone shows respect and consideration for those who can offer them nothing—whether it’s a stranger on the street or a quiet colleague—it’s often a sign of true inner generosity. Conversely, a condescending attitude can betray a need for dominance or a lack of personal confidence . No need for a lie detector: just open your eyes to these simple gestures.
