Redhead Cluster Phenomenon

Peter Watson, in his book Twins: An Investigation Into the Strange Coincidences in the Lives of Separated Twins, related the following story:

Paul Kammerer, an Austrian biologist of the early twentieth century who is chiefly remembered for his fraud over the midwife toad, discovered a "law of series" in which coincidental events run in (say) threes. For example, a bus ticket and a theatre ticket (bought the same day) both bear the number 9, and they are soon followed by a telephone call in which the same number is again mentioned. Kammerer would spend hours, wherever he went, recording the height, hair colour and type of hat worn by every passer-by. He made the observation that men with red hair tended to pass by in clusters with long gaps in between.

This tendency of red-haired men to be seen in clusters is known as the "Redhead Cluster Phenomenon". I'm not sure if it applies to red-haired women as well.

More info about it can be found at the site RhCP, created by Toronto journalist Joe Clark.

A redheaded childhood friend pointed out to me one time that only redheads are truly blonde. Those that we call blonde are only without color. That still puzzles me some forty years later...

Just as you keep seeing Volvos if you've just bought a Volvo, I would suspect this to be down to observation bias.

Sorry, that's not weird at all, and frankly a little boring. But likely to be true, all the same.

KDP, what would your friend say if he saw the albino man living in my area?
