> Of course I can. But are you aware that most people cannot? This reminds me of a strategy I once heard on how to assign weights to people's votes according to their knowledge. You want to assign a high weight to those with relevant knowledge and low weight to those with little relevant knowledge. So how do you know who has good relevant knowledge? Rather than just collecting the response to a question: "How many beans do you think are in this jar?" you also ask the _meta_ question: "What do you think will be the average response to the first question above?" For those who perform well on question 2, you assign higher weight to their answers on question 1. If you just average all the answers to question 1, you are likely to get a close approximation to the true number of beans in the jar. But if you assign weights according to performance on question 2, you can get an even closer approximation to the true answer. I may have gotten some details wrong, but the idea is that if you are aware of your peers' level of knowledge about a topic, then you are likely to be knowledgeable about the topic yourself.
