As surely as [[ugliest man|the ugliest man]] killed God, so did data kill the [[superman]]. The ''will to power'' is defeated by the million-strong dull blades of the ''will to entropy''.

Thirdly, to embrace all the data you can find is to degrade the [[signal-to-noise ratio]]. Even if you buy into the incoherent [[reductionist]] idea that the “signal” is some kind of transcendent truth, by industrialising your data, you risk burying it and if you don’t — if like we pluralists you see ''any'' signal as not just a suitable narrative for your present purposes, the more data you gather, the more possible narratives — conflicting narratives; [[incommensurable]] narratives — you will have. Now this is, for a pluralist, is a good thing: every narrative is a tool in your workshop, the more you have the better you are equipped to deal with the [[unknown unknown]]s our [[complex]] world will surely throw at us — but that tends ''not'' to be what big data disciples are after. | Thirdly, to embrace all the data you can find is to degrade the [[signal-to-noise ratio]].

Even if, from pure data, you ''could'' establish the causal relationship between data you have observed and an event that drives it (it is axiomatic that you ''can’t'': you can only derive a [[correlation]], and we know how spurious ''those'' can be) you still can’t conclude that the cause propelling the ''general'' compelled any ''particular''. | |||
The JC has invoked the [[parable of the squirrels]] to sort this out. | |||
