Charities and other for-good organisations choose to tackle the wicked problems of our world because no one else can. Wicked problems are complex and interconnected social problems that defy a predefined solution. They are problems that require continual development of solutions that behave like Public Goods, which means they are not viable to be provided by the market. And they are problems that mostly affect the marginalised people in our society, which means the state does not tackle them as they do not affect the median voter. Charities tackle wicked problems through offering services that alleviate some the consequences of the problems and through affecting changes in the systems that cause wicked problems.

What are wicked problems

Horst Rittel and Melvin Webber were urban planners at the University of Berkley in California in the 1973 when they wrote an article called: “Dilemmas in a General Theory of Planning”. In it they introduced what they called 'wicked problems'; problems that are difficult or impossible to solve because of incomplete, contradictory, and changing requirements that are often difficult to recognise. Rittel and Webber said that wicked problems have 10 important characteristics:

1. They do not have a definitive formulation.
2. They do not have a “stopping rule.” In other words, these problems lack an inherent logic that signals when they are solved.
3. Their solutions are not true or false, only good or bad.
4. There is no way to test the solution to a wicked problem.
5. They cannot be studied through trial and error. Their solutions are irreversible so, as Rittel and Webber put it, “every trial counts.”
6. There is no end to the number of solutions or approaches to a wicked problem.
7. All wicked problems are essentially unique.
8. Wicked problems can always be described as the symptom of other problems.
9. The way a wicked problem is described determines its possible solutions.
10. Planners, that is those who present solutions to these problems, have no right to be wrong. Unlike mathematicians, “planners are liable for the consequences of the solutions they generate; the effects can matter a great deal to the people who are touched by those actions.”

Why should an almost fifty year old idea about urban planning be relevant to charities and the causes and problems they tackle? Well, the idea didn't stay with urban planning.

Wicked and messy

By 2007, 'wicked problems' had more proponents and a different name. Robert Horn, an American political scientist, called the phenomenon a "Social Mess" and described it as a "set of interrelated problems and other messes. Complexity—systems of systems—is among the factors that makes Social Messes so resistant to analysis and, more importantly, to resolution." According to Horn, the defining characteristics of a social mess are:

1. No unique "correct" view of the problem;
2. Different views of the problem and contradictory solutions;
3. Most problems are connected to other problems;
