Perhaps a more fundamental lesson is that policymakers should find constructive ways to respond to the natural pressure to cut back on stimulus.

In Pavlov's conditioning experiments with dogs, the presentation of food was the unconditional stimulus because it evoked the natural response of salivation in preparation for eating.

As many of us aren't seeing this late afternoon time as the beginning of a natural wind-down to bed, our sleep quality may be affected by keeping up activity and stimulus too late into the evening.
