Wherever the art of medicine is loved, there is also a love of humanity--Hippocrates
The first place I look to seed a discussion is usually Google Trends. It is easy peasy and a lot more user friendly than Google Adwords for example. The visualization below is a quick simplified attempt to demonstrate how quickly you can begin exploring. As we debate healthcare reform I remain an active voice in the narrative--especially as we discuss "value" and the patient perspective.
The first question I ask in a public forum is whether healthcare is a human right or a free market commodity. I know it can be polarizing but I don't think you would argue that potential solutions would be quite different. Being top of mind, I thought I would see what Google searches thought of the matter. The first 2 graphics are US and Worldwide searches respectively. You can see little spikes in interest over time. It might be interesting to see if there are any correlations with real world events--there is a Google Correlate for that...not shown here, but perhaps news headlines or events were driving the sentiment on Google. The worldwide visualization does show an interesting pattern over time when comparing human right vs. free market.
