Thinking, and using the huge available knowledge set available to us, as well as our own expertise is not cynicism, it is called critical thought. Most technically knowledgeable people in an area more skeptical of claims, and they are also more immune to confirmation bias.
When I am looking to invest in mining stocks, I don't ask my dentist nor the guy who drives a truck at the mine. I talk to my friend who is a mining executive and another friend who is a geologist. Using a piece of equipment does not give you expertise. It is like asking someone who drives a car, whether a manufacturers claims of reduced emissions due to platinum/palladium alloys in the catalytic converter is true. Use of something does not confer expertise.
