Question: The Improbability of Because

We like improbable research, obviously. But we often puzzle at a rule of thumb some people use.

Their guiding principle:
Improbable explanations are probably the best explanations — because they are improbable.

This rule of thumb is suggested by two items in the news this week. One is in a February 12, 2007 CNN/AP dispatch:

RobertJahn.jpgReport: Princeton ESP lab to close after 28 years

PRINCETON, New Jersey (AP) — The extrasensory perception lab at Princeton University will be shuttered at the end of the month. Maybe you already knew that.

The Princeton Engineering Anomalies Research laboratory will close after 28 years of studying ESP and telekinesis, research that embarrassed university officials and outraged the scientific community.

PEAR’s founder, Robert G. Jahn, said the lab, with its aging equipment and dwindling finances, has done what it needed to do.

“If people don’t believe us after all the results we’ve produced, then they never will,” Jahn, 76, former dean of Princeton’s engineering school and an emeritus professor, told The New York Times for Saturday editions.

The other is in a February 9, 2007 report in the Register:

JonathanCainer.gifPsychic museum closes due to unforeseen circumstances

York Psychic Museum has shut due to unforeseen circumstances, the York Press reports.

Astrologer Jonathan Cainer, who opened the museum in 2003, admitted that he’d been welcoming just 100 people a week through the doors, and had accordingly decided to temporarily hang up his crystal ball.
