But the leading explanation seems to be that they were enthralled by the company’s charismatic young founder. Laudatory magazine cover articles about Holmes have been so numerous that the phenomenon has itself been a topic of discussion.

Theranos’ board of directors also lacked anyone with expertise in laboratory testing or medical diagnostics. This should have been a warning sign.

Show me the data

Just a few weeks before regulators proposed banning Holmes and Theranos President Sunny Balwani from the blood-testing industry, the company tried to remedy this by bulking up its medical advisor board with well-qualified experts in chemistry, pathology and clinical chemistry.

It’s hard to imagine these experts would have signed on amid all the bad publicity and allegations without demanding proof that the technology works, but who knows?

It still remains possible that Theranos has discovered a breakthrough technology that can do hundreds of lab tests on a drop of fluid from a patient’s finger. But even if this increasingly unlikely prospect is a reality, Holmes’ erstwhile acolytes need to remember the lessons learned from the pantheon of past pied pipers and summed up by statistician W. Edwards Deming:

In God we trust; all others must bring data.
