Q2049On Japanese railways, drivers and platform staff point at signals, gauges and doors while calling their status aloud — a ritual called shisa kanko. In a railway institute experiment, the habit cut errors on a routine task to about one-sixth.
The gesture looks theatrical to visitors — a white-gloved conductor pointing down an empty platform, announcing 'all clear' to nobody. But the mechanism is sound: pointing forces the eyes to the object, speaking forces the mind to commit, and together they interrupt the autopilot that lets a familiar task slip past unchecked. The figure comes from a laboratory task rather than accident records, so hold it loosely; New York's subway adopted a pointing-only version anyway.
