XKCD vs. John Campbell

According to XKCD, the lack of use of psychic phenomena is a major argument against the reality of such woo:

Eventually, arguing that these things work means arguing that modern capitalism isn't that ruthlessly profit-focused.

On the other hand, according to John Campbell editorials, businesses do use psychic phenomena … but keep it secret.

On the gripping hand (am I overusing that phrase?), the mainstream media haven't uncovered that. That means:

• They're missing an opportunity to do some scandal mongering (superstitious capitalists are wasting YOUR money!).
• A bunch of humanities majors are missing an opportunity to bash the people who passed the classes they flunked.

I won't more than mention the fact that the numerous claims across the Internet that oil companies use dowsers tend to be short on specifics.
