text: People have different knowledge of topics that help them throughout the choice making process. My mother and I have completely different knowledge bases because she is a physical therapist and I am still in middle school. Once, I had a knee that was inflamed and I thought that the problem was I had twisted it, but my mom observed how I was walking and realized that my shoe was causing the problem; my shoe didn't support my arch, so my foot would roll inward, causing my knee to as well. I had no idea that it was my shoe that was causing the issue, but because my mom had different knowledge than I did she was able to figure it out. Problem solving and choice making both involve using past knowledge to do the best thing now. Having a second person with different knowledge than you gives you a second opinion which is extremely useful to make the best choice.
