Before the course is built
Setup asks about your situation first.
Lesson 1 opens on the moment you describe, and the examples use your role. For this request, expect questions like these.
- What drew you to this: a disagreement about what happened, curiosity, or something professional?
- Do you trust your memory a lot, or too little?
- Is there a memory you have started to doubt?
Right for now
If any of this sounds familiar, start here.
Vivid feels true
The detail is so clear that doubt seems absurd.
You rely on memory professionally
Testimony, interviews or notes matter, and you would like to know their limits.
Course arc
Where the course goes, in order.
Cadence writes the lessons for you, so the exact path follows your answers. This is the ground a course built from this sentence covers.
01 / 06Memory is not a recording
Reconstruction, and why every recall is partly a rebuild.
Attention decides what gets in
Why you did not see the gorilla, and what that means for what you remember.
Suggestion and retelling
How questions, conversations and time reshape what you recall.
Confidence and accuracy
Why vividness and certainty are poor guides to truth.
Memory in disagreements
Why two honest people remember differently, and how to handle it.
Living with a reconstructive memory
When to trust it, when to write things down, and how to argue less about the past.
What changes
What you will be able to do, and what you will stop believing.
You will be able to
Explain how memory works
Describe encoding, storage and reconstruction in plain terms.
Recognise the failure modes
Know how suggestion, time and retelling change a memory.
Hold memories with appropriate confidence
Trust them for some things and check them for others.
Ideas this course corrects
Vivid memories are accurate memories
Vividness tracks emotion and rehearsal, not accuracy. Flashbulb memories are famously wrong in detail.
Memory fades but does not change
It changes every time it is recalled. Fading is the least of it.
Course questions
