Recently one of those increasingly familiar New York Times editorials disguised as news stories was headlined "Conservatives Help Wal-Mart, and Vice Versa."

There was a chart with photos of people from conservative think tanks saying things favorable to Wal-Mart's side of the controversies surrounding that company, along with dollar amounts over them and their statements, indicating how much Wal-Mart had donated to the think tanks where these individuals work.

Buried deep inside the story, near the end, there was a passing comment that "labor unions have financed organizations that have been critical of Wal-Mart." But there were no people or statements singled out with dollar amounts over them.

The double standard was evident in another way: The damning charge was that these conservative think tanks and the scholars who work there "have consistently failed to disclose their ties" to Wal-Mart.

There was no charge that liberal think tanks like the Brookings Institution, or the scholars there, "failed to disclose their ties" to their donors.

It is very doubtful if most of the scholars at either liberal or conservative think tanks know who all the many donors to these institutions are -- or care.

For one thing, there is money coming from all points of the political compass and from a whole spectrum of special interest groups. You can say whatever you feel like and, if it doesn't suit one think tank, it will suit another.

It so happens that I work for a think tank, though not one mentioned in this New York Times "news" story, and I could not name five donors to the Hoover Institution if my life depended on it, though I am sure that there are far more than five.

For all I know, I may have defended some of those unknown donors -- or I may have bitten the hand that feeds me by attacking them in this column.

It is by no means unknown for different scholars at the Hoover Institution to come out publicly on opposite sides of controversies. Nor is that unknown at other think tanks, liberal or conservative.

Why then should we "disclose" -- even if we knew -- who the donors are, as if we were delivering commercials for our sponsors?

Why do conservative donors contribute money to conservative think tanks or liberal donors contribute money to liberal think tanks? Is it rocket science that people are more likely to contribute money to those they agree with? Continued...
