Question
Why does surprise journal fail?
Quick Answer
Filtering for 'important' surprises and ignoring small ones. The small surprises — the colleague who disagrees when you expected agreement, the metric that ticks up when you predicted flat — are precisely the ones that reveal systematic blind spots. Big surprises are obvious enough that everyone.
The most common reason surprise journal fails: Filtering for 'important' surprises and ignoring small ones. The small surprises — the colleague who disagrees when you expected agreement, the metric that ticks up when you predicted flat — are precisely the ones that reveal systematic blind spots. Big surprises are obvious enough that everyone notices. Small surprises are where your personal model diverges from reality in ways only you can detect.
The fix: For the next 48 hours, carry a capture tool and tag every surprise with the prefix 'S:' — even tiny ones. 'S: The coffee shop I assumed closed on Mondays was open.' 'S: That API call returned in 20ms when I expected 200ms.' 'S: My partner remembered a detail from a conversation I forgot we had.' At the end of 48 hours, review the list. For each entry, write one sentence answering: 'What did I apparently believe that turned out to be wrong?' You now have a map of where your mental models are miscalibrated.
The underlying principle is straightforward: Surprise indicates a gap between your model and reality — always worth noting.
