The Most Embarrassing Graph in Modern Physics

Scientists don’t always agree with each other. Yes, I know; shocking but true. In cases of collegial disagreement, it’s often fun to quantify the extent of opinion by gathering a collection of experts and taking a poll. Inevitably some killjoy will loudly grumble that “scientific questions aren’t decided by voting!”, but that misses the point. A poll of scientists isn’t meant to decide questions, it’s meant to collect data — mapping out the territory of opinion among people who have spent time and effort thinking carefully about the relevant questions.

There’s been a bit of attention given recently to one such poll, carried out by Maximilian Schlosshauer, Johannes Kofler, and Anton Zeilinger at a quantum foundations meeting (see John Preskill at Quantum FrontiersSwans on Tea). The pollsters asked a variety of questions, many frustratingly vague, which were patiently answered by the 33 participants.

This plot gives the money shot, as they say in Hollywood:

Quantum Poll

It’s a histogram of the audience’s “favorite” interpretation of quantum mechanics. As we see, among this expert collection of physicists, philosophers, and mathematicians, there is not much of a consensus. A 42% percent plurality votes for the “Copenhagen” interpretation, while the others are scattered over a handful of alternatives.
