It takes no more research than a trip to almost any public library or college to show the incredibly lopsided coverage of slavery in the United States or in the Western Hemisphere, as compared to the meager writings on even larger number of Africans enslaved in the Islamic countries of the Middle East and North Africa, not to mention the vast numbers of Europeans also enslaved in centuries past in the Islamic world and within Europe itself. At least a million Europeans were enslaved by North African pirates alone from 1500 to 1800, and some Europeans slaves were still being sold on the auction blocks in the Egypt, years after the Emancipation Proclamation freed blacks in the United States.

When I was an undergraduate studying economics under Professor Arthur Smithies of Harvard, he asked me in class one day what policy I favored on a particular issue of the times. Since I had strong feelings on that issue, I proceeded to answer him with enthusiasm, explaining what beneficial consequences I expected from the policy I advocated.
“And then what will happen?” he asked.
The question caught me off guard. However, as I thought about it, it became clear that the situation I described would lead to other economic consequences, which I then began to consider and to spell out.
“And what will happen after that?” Professor Smithies asked.
As I analyzed how the further economic reactions to the policy would unfold, I began to realize that these reactions would lead to consequences much less desirable than those at the first stage, and I began to waver somewhat.
“And then what will happen?” Smithies persisted.
By now I was beginning to see that the economic reverberations of the policy I advocated were likely to be pretty disastrous — and, in fact, much worse than the initial situation that it was designed to improve.
Simple as this little exercise might seem, it went further than most economic discussions about policies on a wide range of issues. Most thinking stops at stage one.

Intellectuals may like to think of themselves as people who "speak truth to power" but too often they are people who speak lies to gain power.
