Source Monitoring

Shrink Definition

Source monitoring is the mental work of tracking where a memory or belief came from, whether you saw it, heard it, read it, or imagined it. When this tracking fails, we can confuse the source, thinking we witnessed something we were only told. It underlies false memories and misattributed ideas. Knowing what happened is different from knowing how we know it.

Plain language

Keeping track of where a memory or belief actually came from.

Shrink Insight

Remembering a fact and remembering its source are two different jobs.

Why it matters

It explains false memories, misremembered advice, and unintentional plagiarism. It supports checking the origin of a belief, not just its content.

Common misunderstanding

People assume if they remember something, they remember where it came from. Source and content are stored separately, and the source is easy to lose.

Shrink Perspective

Ask not only what you know, but how you know it.

Shrink Reflection

What do I believe firmly without recalling where I learned it?

Shrink Step

For an important belief, try to trace exactly where it came from.

Shrink Minute

Notice one thing you're sure of but can't say where you learned it.

Shrink Takeaway

Knowing something isn't the same as knowing its source.
