It is, though. The taxi driver ABS trial was a near-perfect
double-blind study and it showed that those driving ABS equipped cars
accelerated harder, braked harder, drove faster and followed closer.

What particular form of psychic capability was reckoned to account for this,
then ? As soon as any driver realised his vehicle had ABS, the trial failed
the double-blind test, which demands that those taking part and the
observers are both ignorant of the conditions.

The condition being tested was "driver knowingly driving ABS equipped
car". The drivers did not know which cars were fitted with measuring
devices, and the observers did not know which measuring devices
werefitted to cars with ABS.
