Michael starts the conversation by declaring that social media is a record of, "all of the stuff you don't normally do." Neither Blair, Erin or Mark could disagree so we moved on to the topic of expertise, addressing differences between that derived from actual experience rather than from a credentialing body or process and the value of each, as well as how expert conclusions are often shaped by funding (we see you, Nutrition). If science results from consensus, i.e. from a number of people testing different hypotheses and settling on a conclusion, does this mean that the consensus is always right, or true, or useful? Big jumps in understanding often result from individuals not doing the same as had been done before, not following the consensus. So maybe we should all speak up when folks tell us to keep our in-expertise to ourselves.
