Marcus told his classmates he knew everything about sharks.
He knew many facts, but not everything.
The problem began when his teacher invited a marine biologist to class.
Before the visit, Marcus answered everyone’s questions confidently.
“Yes, all sharks must keep swimming.”
“Yes, sharks never get sick.”
“Yes, the biggest shark is the great white.”
During the presentation, Dr. Kim explained that some sharks could rest without swimming, sharks could become ill, and whale sharks were much larger than great whites.
Everyone looked at Marcus.
He wished the floor would open.
After class, his friend asked why he had lied.
“I thought those facts were true.”
“You said you were an expert.”
Marcus felt angry, then embarrassed.
He approached Dr. Kim and admitted what happened.
She smiled.
“Scientists say ‘I don’t know’ constantly.”
“That doesn’t sound expert.”
“It is one of the most expert things you can say.”
For the next class project, Marcus created a presentation titled SHARK FACTS I WAS WRONG ABOUT.
He explained each mistake and where the correct information came from.
Students laughed, but not cruelly.
Marcus added a final slide:
Questions I Still Don’t Know
The list was longer than the presentation.
Dr. Kim emailed answers to some and suggested books for others.
Marcus remained the student who loved sharks.
He stopped calling himself an expert.
Strangely, classmates trusted his answers more after he began saying, “I’m not sure—let’s check.”
Confidence had once meant never appearing uncertain.
Now Marcus understood that real knowledge included knowing where its edges were.
