“The use of [[placebo]] buttons is more common than we realise. Man**y pedestrian crossings have buttons that also have no effect at all – the traffic lights are set to a timed sequence**. However, here the presence of the button is a rather more benign lie: **how many fewer people would wait for the green man if there were no button to press?** And how many more people would wait for the green man if there were a digital display of the seconds to wait before its appearance? In countries including Korea and China, **accidents at intersections have been reduced by simply displaying the number of seconds remaining before the lights turn green**.” --- **Tags** -- , [[quotes]], [[placebos]] , [[psycho-logic]] , [[alchemy]] , [[environmental-design]] , **Source** -- [[202407221554 - B - Alchemy]]
