&gt; I wonder how popular this viewpoint will be here on HN - the home of lifehacking and microanalysis of bodyfunction (often without the corresponding knowledge to go with it, but prefaced with a view that &#x27;more data will always be better&#x27;).<p>This would be what I see as the fundamental flaw behind Theranos, even if their technology worked (works?) as promised: the idea that more data will always be better is sophomoric (and I select that word judiciously, considering the founder). Evidence-based medicine clearly shows that more data does not, in itself, lead to a better outcome.
