The Cost of Assumptions

Have you ever found yourself saying one of these phrases?

"I thought someone else was handling it."

"I assumed you knew."

"I didn't realize that was important."

"I thought we were on the same page."

If so, you're not alone.

In my experience working with chambers, nonprofits, businesses, boards, and leadership teams, assumptions are responsible for more frustration, confusion, and conflict than almost anything else.

The challenge is that assumptions often feel like facts.

We assume someone understands the deadline. We assume a volunteer knows their role. We assume a team member interpreted our instructions the same way we intended them. We assume everyone has the same information.

Then we become frustrated when the results don't match our expectations.

The truth is that assumptions create gaps. Communication fills them.

One of the simplest lessons I've learned over the years is that what is clear in your head is not always clear to someone else.

As leaders, we often move quickly. We know the history behind a decision. We understand the context. We see the bigger picture. The people around us may only be hearing part of the conversation.

That's why great leaders ask questions instead of making assumptions.

They ask:

• What questions do you have?

• How do you understand the assignment?

• What obstacles do you see?

• What support do you need?

These conversations may take a few extra minutes, but they often save hours of frustration later.

The same principle applies to relationships.

How many disagreements start because someone assumed another person's intentions?

We assume they were being rude. We assume they don't care. We assume they ignored us on purpose.

In reality, they may simply have been overwhelmed, distracted, or operating with different information.

Assumptions rarely bring clarity. They usually create stories that may not be true.

The next time you catch yourself assuming, pause and ask.

Clarify before you conclude.

Confirm before you react.

Communicate before you criticize.

You may discover that the problem wasn't a lack of commitment, effort, or care.

It was simply a lack of understanding.

At Starfish Partnerships, I help teams strengthen communication, improve trust, and create cultures where expectations are clear and conversations are productive. Sometimes the biggest breakthroughs come from replacing assumptions with honest dialogue.
