[Taxacom] Filling the world with biodiversity data errors

 The analogy is a poor one anyway. All it really says is that to survive, one only has to be better than the competition, but this isn't about the survival of Plazi/Zenodo! It is about doing all we reasonably can do to either prevent the generation of errors*, or, better, to allow rapid fixing of errors when they do occur.Stephen*Whether an error is trivial or serious depends on the context of what one is trying to do. For example, if one was simply counting the number of species of everything recorded from Iceland, then one extra doesn't make much difference. However, if one were using Plazi to research Zenascus luniger, then the error becomes much more serious.

 In other words it is better for two to outrun the bear than one :)

 PS: I forgot to mention that I don't blame anyone for making errors, but I just think it important that any errors get fixed asap. That is the whole point, i.e. provide an efficient error correcting facility. It isn't about blame, it is about fixing it.

  Well Rich, it rather depends on the frequency of such errors, which I don't have any grasp of, at present. If the frequency of such errors is low, say 1%, then there isn't much of a problem (unless you particularly want data on Zenascus luniger!) However, if the frequency of such errors is high, which might be the case, as far as I know, then there is more of a problem, even if it is the best of the available alternatives. Assuming that the data does actually get used by somebody for some purpose, a high proportion of such errors isn't necessarily better than nothing! Imagine if the species was added to the list of protected threatened species of Iceland, on the basis that there were so few known specimens and subsequent surveys turned up none! The mythical extinct Icelandic aderid! Anyway, I don't see anything wrong with pointing out that there is room for improvement!

 Two guys walking through the woods.  A huge bear starts to charge them.  The first guy sits down to put on his running shoes.  The second guy says, "Are you crazy?!? You'll never out-run that bear!" The first guy says, "I don't have to out-run the bear. I just have to out-run YOU."

Moral of the story: You don't need to perfect.  You just need to be better than the alternative.  From where I sit, what PLAZI is doing is far, FAR better than the alternative!  

Keep those running shoes on, Donat!

Aloha,
