Deliberation may be the most important field of research humankind will engage in the 21th century. Deliberation is so important, because every group of people as small as a group composed of two people, like a couple, to groups as large as hounderds of milions, like states, needs to find solutions that will help their members prosper. To prosper, all groups have to arrive at the best solutions available in their current situation. Deliberation is a field of research that engages the ways people can work together, with corroborated knoweldge to pursuit the best solutions. If we will understand how to promote together the best solution through agreements, we will find ways to bring prosperity to wider population, and we may also bring more peace among nations.
