Your Investigation Relies on a False Premise: Memory Is Not a Video Recording
Most organisations still treat human memory as if it’s a GoPro — a flawless replay waiting to be downloaded.It isn’t.
When people recall an event, they don’t retrieve a perfect file.They reconstruct a story, filling the gaps with assumptions, expectations, and fragments of what felt true in the moment.That’s why two credible people can describe the same incident completely differently.
The biggest limitation in learning from failure isn’t honesty — it’s how the brain works.
Memory Is a Feature, Not a Flaw
When someone says, “I can’t recall,” it’s not laziness — it’s physiology.Human memory is designed to prioritize emotion and meaning over detail.That shortcut helps us survive, but it also means post-incident recall is unreliable unless it’s guided correctly.
As leaders, this isn’t something to be frustrated by — it’s something to design around.If we expect perfect recall under pressure, we’re building our learning systems on incomplete foundations.
Manage the Interview, Not the Witness
This is where structured, evidence-based techniques matter.The Cognitive Interview, developed by Fisher and Geiselman, deliberately works with memory’s architecture.
It uses context reinstatement — sight, sound, sequence, and sensory cues — to help people safely re-experience the moment.It invites multiple perspectives and reverse-order recall, bypassing the brain’s tendency to fill blanks with guesswork.
It’s not about “what happened?”It’s about helping the mind find its way back to what really did.
The Leadership Imperative
If your investigators still rely on rapid Q&A sessions, they’re chasing precision from an imprecise tool.It’s time to upgrade your approach to memory as you would any other system.
Teach your leaders and investigators how to work with the human operating system — not against it.That’s how we move from stories to truth, and from data to learning.
Question for Leaders:How is your organization training its leaders and investigators to overcome the reconstructive nature of memory?
