There has been a longstanding tug-of-war between those wanting to make leadership more scientific and those who want to make it more practical. We could restrict the scope to establish a regulatory policy ad hoc. However, a better solution would be to have a public debate first, reach a consensus, and then institute the regulatory process through the legislative branches of our governments.
The way to balance conflicts of interest is to include proponents of all major interest groups in the debate, which is desirable if not mandatory, before the regulatory policy is cast in concrete. Governments should use scientifically sound recommendations and establish a bipartisan law.
