Seat belt usage: A potential target for applied behavior analysis.

The authors looked at cars that buzz until the driver buckles. They asked: do these buzzers really make people wear belts?

They checked factory data and police reports. Most drivers were disconnecting the buzzers.

Six out of ten drivers had unplugged the buzzer. Belt use stayed low.

The paper warned: if people can shut off the annoyance, they will.

Two years later Berler et al. (1982) flipped the script. They gave raffle tickets only to drivers who were buckled. Belt use jumped from 26% to 46%. The buzzer failed; the prize worked.

Glenn (1983) repeated the idea with token fliers at a factory gate. Again, afternoon departures doubled. The positive approach kept winning.

Van Houten et al. (2005) and Van Houten et al. (2011) moved from rewards to engineering. A short gear-shift delay or a stiff gas pedal that eases only after buckling pushed non-users to 100%. The field shifted from “beep at them” to “make buckling easier than driving”.

If you design safety programs, skip the nagging buzzer. Give drivers something they want, or change the car so the belt must click before the wheels move. Positive contingencies and smart prompts beat aversive alarms every time.
