Public image is extremely important in American society and I observed personally that the Presidency of John F. Kennedy did much in the public mind for Harvard. Harvard was an excellent school before Kennedy, but Kennedy embodied a new vision for the United States: a leader who caught the world's imagination and that reflected on his alma mater, Harvard.

I would not say that Harvard possesses any sort of absolute dominance. And I personally do not take the rankings of schools all that seriously. However, I think that Harvard's global visibility increased significantly in the 1930s and 1940s and that the new commitment to excellence at Harvard spread to other institutions.

If we want to identify the great success of American research universities, and that success goes far beyond Harvard, we have to come back to the question of governance. Excellence requires a firewall between trusteeship, or government ministries, and the academic decision-making process. This American concept of shared governance wherein the faculty are engaged in running the university as part of a collaboration with the other stakeholders.

That doesn't mean that the top fifteen institutions in the ranking somehow don't belong there at all. But what is the difference between number two and number eight in any meaningful sense? As an administrator who worked to build a complex university, I find the assumption slightly offensive. We need to be committed to excellence, not to lists.

Never underestimate the difficulty of changing false beliefs by facts

There are many in East Asia who simply judge students on the basis of national tests. The top universities in the United States do not do that, and for good reason. We need a careful process for admissions that take all sorts of factors into account: different intellectual strengths, artistic expression, economic standing, social background, ethnicity, regional representation and designs a class as a balanced whole.

Shared governance is often the critical element that is missing in Asian universities, no matter how talented the faculty may be. Either it is ministries of education that are trying to run things, or in private institutions - those who control the funds. Neither group knows much about teaching and research.
