Did you know that intentionally creating a sense of “favors owed” can be an effective way to improve workplace relationships?
We often think, “I don’t want to be a burden, so I’ll handle this on my own,” but in reality, a healthy balance of mutual reliance is the key to building deep trust.
In this article, we’ll explain the mechanisms behind “psychological debt” and “helping behavior” from a psychological perspective and introduce specific techniques to improve communication in the workplace.
1. Why does having a “debt-and-credit” dynamic deepen trust?
Experimental data shows that relationships where people ask each other for favors build stronger bonds of trust than those where colleagues never ask for anything.
This is related to the human instinct known as “psychological debt.”
“Psychological debt” fosters cooperative relationships
When people receive help from someone, they enter a psychological state where they feel they “must repay the favor.”
In psychology, this is called psychological debt (the principle of reciprocity).
- Unconscious Reciprocity
When someone is helped, they unconsciously feel motivated to think, “Next time, I’ll be the one to help.” - The Cycle of Mutual Support
If you extend a helping hand first, it becomes easier to get help from others when you’re in a bind. - Deepening Mutual Understanding
Since helping each other leads to more interaction, it provides an opportunity to gain a deeper understanding of the other person’s work and character.
Point to Note: Differences Based on the Relationship
However, when a supervisor helps a subordinate, the subordinate tends to view this as “part of the supervisor’s natural role” and is less likely to feel indebted.
Furthermore, it is important to be careful not to come across as overly patronizing, as this can hurt the other person’s self-esteem and have the opposite effect.
2. When Are People Most Likely to Want to Help? Lessons from Cunningham’s Experiment
Whether someone is willing to help depends largely on their “current mood.”
An experiment conducted by American psychologist Cunningham reveals some interesting findings.
Good things make people kinder
Cunningham’s “10-cent coin in a payphone” experiment yielded the following results:
- People who unexpectedly found 10 cents
Are about 70% likely to help someone in need - People who didn’t find any money
Are about 40% likely to help
In other words, when people are in a good mood because something “slightly positive” has happened, they are more likely to help others.
Guilt can also trigger helping behavior
In another experiment using a hidden camera, approximately 80% of people who “believed” they had broken someone else’s camera offered to help.
This is because they were motivated by the desire to alleviate their own guilt by helping others.
3. The 3 Best Times to Ask for a Favor at Work
Leverage psychological insights to target moments when the other person is most likely to say yes.
① When the other person is in a good mood
Positive emotions lower the barrier to helping others.
Immediately after a project succeeds or when something good has happened in their personal life, the likelihood of them accepting your request increases.
② When the other person feels guilty
People who feel guilty about a work mistake or similar situation tend to try to make up for that negative feeling by “being helpful to someone.”
It’s effective to offer a light request for help after acknowledging their mistake.
③ Immediately after they’ve finished a task
After completing a major task, a sense of accomplishment and relief creates mental space.
- An Extra Tip
If you ask for a favor while praising the other person’s achievements—saying something like, “That’s impressive!”—you’ll satisfy their need for recognition and encourage them to be more cooperative.
4. Etiquette for Maintaining Good Relationships
Japanese people tend to particularly dislike assistance that makes them feel vulnerable or that damages their pride.
When you find yourself in a position to help, keep the following points in mind.
- Don’t hurt the other person’s self-esteem
Avoid acting as if you’ve “done them a favor.”
Make sure to maintain a “we’re all in this together” attitude. - Create an atmosphere where it’s easy to ask for help
When asking for help, don’t try to appear perfect; showing a little vulnerability makes it easier for others to lend a hand.
Summary
Favors exchanged at work are not merely a burden; they are “capital of trust.”
Ask for help at the right time, and offer assistance with the right level of consideration.
By understanding this psychological mechanism, let’s work together to build a stress-free workplace environment.
