Perhaps people who are accomplished scholars in political theory and economics and a few other relevant areas?

Think of it like an investment. You can put all of your money on one really volatile stock. Maybe it will do really great! But maybe you will lose 95% of your money in an hour. Or, you can put it in a basket of carefullly-chosen stocks that have the collective goal of a slow, steady climb in value while limiting volatility.
Different goals.
