Business plans with too much detail, books with too much proof, politicians with too much granularity... it seems as though more data is a good thing, because data proves the case.
In my experience, data crowds out faith. And without faith, it's hard to believe in the data enough to make a leap. Big mergers, big VC investments, big political movements, large congregations... they don't usually turn out for a spreadsheet.
The problem is this: no spreadsheet, no bibliography and no list of resources is sufficient proof to someone who chooses not to believe. The skeptic will always find a reason, even if it's one the rest of us don't think is a good one. Relying too much on proof distracts you from the real mission--which is emotional connection.
