There are 3 main ways Humanism helps people solve problems.  

Explanation:

1. Rejection of supernaturalism-  If something can’t be proven to work as a solution to a problem then there is no point in us wasting time, energy and money on it. We look for solutions that have proven their efficacy - and so reject supernatural solutions.

2. We judge solutions based on compassion- A solution is deemed good if it helps people and bad if it hurts people. We want to create the solutions that do the most good for the most people and do the least harm. We are not looking for solutions to get revenge. We do not look for solutions that help us and hurt our community. We are looking for win win solutions.

3. We recognize our fellow humans as being fully human- This helps with problem solving because most of our problems involve other people and the solutions require the help of other people. Treating people with dignity helps us to avoid common thinking mistakes that result from dehumanizing other humans and discounting their knowledge and perspectives. The result is - we are slightly less likely to fall prey to certain fallacies that involve dismissing knowledge because you don’t like the person sharing the knowledge. Additionally, because we attempt to check our biases, we also do better at including people and making people feel valued and this helps them want to help us collectively solve our problems.
