Whodunnit Awareness Test
Watch a short mystery unfold, then see how much of it you actually retain once the story is asking something of you.
History
This test is styled as a short mystery scene rather than a straightforward counting task, drawing on eyewitness-memory research showing that people are surprisingly unreliable at recalling the details of a busy scene — especially once they're actively trying to solve something within it. Framing the exercise as a whodunnit adds exactly that pressure.
The setup
You watch a short clip in which something happens — an object goes missing, an action is taken — and you're asked to work out who did it or what gave it away. Your attention is split between following the unfolding story and searching the scene for clues, which is precisely where things start to slip past you.
What it helps you notice
It highlights the gap between watching something and actually encoding its details — relevant to eyewitnesses, security staff, and anyone who assumes that paying attention and remembering accurately are the same thing. Questions it tends to raise:
- Could you name the culprit on your first watch?
- What detail did you actually rely on to decide?
- What was in plain sight the whole time that you missed?
