Uncertainty leads to situation evaluation
One of the fundamental human fears is uncertainty. Many people lived long in a bubble, thinking that their life could never take on the wrong path. They ignored their dynamic surroundings with the premise that they can't change the outside world, but only what's inside them. Concentrating only on what we can do is just a sign of egoism—we are aware of the problems, but don't seek change. This is wrong even if our resources are limited.
Uncertainty in a global world is almost equal to panic. People aren't aware, but they become panic generators as soon as bad, life-threatening news reach them. They start to openly share their problem with others in an attempt to get attention. Once this happens, negativity spreads through the entire social network. A saturated, overloaded "router" of such a network will need time to release that burden. This won't happen, if it accepts quicker new negative information than it releases old one. Being overloaded, people become even more news-driven.
Uncertainty is a chance, because the crisis is just another opportunity. Only that this opportunity can't be exercised by a single person or company in a way other opportunities can. It requires meta-collaboration that crosses companies, country borders, race and religion and focuses on the people as main actors. But this strengthens politics.
Uncertainty can also help us evaluate our beliefs, values and priorities. If we see that our life is in danger, we do everything to preserve it—it's our basic survival instinct, so we'll have to reevaluate our lives. We can change our behavior then to reflect the new circumstances we are living in.
If we don't plan and act thinking about the long-term, uncertainty will be certain. To increase our likelihood for change, we need a supportive system.
