[Taxacom] Data query, ETC.

Hi,

a colleague of mine, working on red deer populations control,
refused to rely on official declarations of deer kills by hunters,
and imposed the collection of the mandibles of the killed animals

immediately, the annual kill showed a sudden "drop" of some 17 %
this was due to previous false declarations by hunters
(there were punished if they did not kill their quota,
so they tend to declare more than they really killed...)

now, the exhaustive collection of the left mandible
of each and every killed animal works pretty well :
the hunters play the game by the rules
and their benevolent work is very useful to the scientists

so I agree that proto-data become scientific when controlled by a 
scientist,
and the scientist is judge of the reliability of the record - and their 
interpretation

there is much more to scientificity than data quality and testability of 
hypotheses
(connexion with other scientific theories, scientific background 
knowledge...)
but this is another story

best,
Pierre
