Social proof can save your life

Back when I read Robert Cialdini's book Influence, he discussed a paper which showed how two drivers who happen to change lanes at the same time can cause many drivers to follow suit. These other drivers think there is a special reason why the first cars changed lanes, such as spotting a driving hazard or seeing the other lane is free. That potentially also endangers others on the road, aside to leading them on.

This of course was given as an example of when social proof goes wrong. A theme through his book is that these "tools of influence", such as social proof, are very useful outside of the potential for their abuse.

In today's busy world, surrounded by clatter and numerous micro decisions, a concept such as social proof can be very useful. "Everyone buys these shoes, they must be better. Or at least well liked."

This of course leads to "If that guy can go through that red light, maybe he knows something I don't and it's not working. Or.. maybe they don't ticket you here. I should follow."

And finally to "Oh! You mean everyone else jumps off the roof? I must do that too!" :)

While driving a few days ago I noticed that the other cars at the intersection were not advancing. I slowed down and a police car buzzed by at incredible speed. I would have seen it a couple of seconds later, but social proof did potentially save my life.

This happened to me before. I would notice people driving strange, or changing lanes. Sometimes I'd follow. Other times I'd deduce it is pointless, silly or dangerous. But ever since this police car incident I watch the cars around me far more closely.

Rather than look at individual cars and the psychology of their drivers to try and figure out when a car is going to cut me, I now also consciously and regularly watch for car group psychology.

As a general rule, when group psychology comes into play on the road, keep your distance.

If I spot nothing wrong other than a snowball effect of people stopping/acting stange, I can always just pass them, leading the way. Letting them eat my dust. :)

Anyone has any idea what that paper on driving psychology and social proof was? Any other pointers?
