How to achieve truly international cooperation?

Too many social scientists are busy with maintaining or improving their position and/or of that of the organisation they are working for. This prevents truly international cooperation and stimulates work that is geared towards defending certain 'scientific' positions or postures or stances and often results in analyses that come close to propaganda or whitewashing existing policies -- without making explicit that they serve that interest.

Maybe this unfortunate state of affairs is in particular present in economic policy analyses and is less present in fundamental economic research that makes explicit the assumptions of the research.

To apply my thought on the need for a better world economic system: how could we stimulate social scientists to work jointly -- regardless of the interests of individuals and institutions -- on a plan that suggests how the world economic system could be improved?

Obviously, such a plan needs to be discussed democratically, by all nations. And obviously, this should be done in a truly democratic way and not in the current way in which people are degradated and used as a flock of animals who, by voting in elections, serve to legitimise current unequality, poverty and economic and social injustice.
